NSPredicate like NSLiteralSearch
This works. i.e. returns {0,1}:
NSRange r2 = [ @ก่ี rangeOfString: @ก options: NSAnchoredSearch |
NSLiteralSearch ];
(without NSLiteralSearch it returns NSNotFound).
but an NSPredicate with: someProperty BEGINSWITH ก does NOT find ก่ี.
(the NSPredicate is to be used with -[NSArrayController setFilterPredicate:] to
query Core Data).
So: is there some string_option equivalent to NSLiteralSearch?
And a related question: where are the available string_options defined?
The Predicate Programming Guide has:
string_options ::= c | d | cd
but also an example with w:
((* = FooBar*wcd)) || (kMDItemTextContent = FooBar*cd))
10.6.2
Kind regards,
Gerriet.

Re: memcpy with 64 bit
malloc/calloc is a better way. «Mac OS X implements a highly-tuned, threadsafe allocation library, providing standard implementations of the malloc,calloc, realloc, and free routines, among others. If you are allocating memory using older routines such as NewPtr or NewHandle, you should change your code to use malloc instead. The end result is the same since most legacy routines are now wrappers for malloc anyway.» from http://developer.apple.com/mac/library/documentation/Performance/Conceptual/ManagingMemory/Articles/MemoryAlloc.html Le 15 déc. 2009 à 09:50, gMail.com a écrit : Ouch!

Re: pls explain rotated iPhone coordinates to me
This seems wrong. When do you call this code? Usually it is just enough to set the springs of your scroll view in IB. Then, after rotation, refit your content. atze Am 15.12.2009 um 03:46 schrieb Matt Neuburg: I am not grasping how coordinates work in a rotated iPhone app, and I'm hoping someone will explain them. My goal is a scroll view consisting of two equal pages side by side with the iPhone sideways (landscape). I have accomplished this, but I don't understand how I did it; I used pure trial and error, and what works makes no sense to me. Here's what I did. The scroll view occupies the entire window (except for the status bar, of course). It has a view controller implemented so as to permit the autorotation, and the plist tells us to start up in landscape mode. And we do. So far so good. Now I populate the scroll view. I want its content to be double-wide, but I have to widen its *height* (svc is the scroll view's controller): CGRect f = svc.view.frame; CGSize sz = CGSizeMake(f.size.height * 2.0, f.size.width); // swap!

compleation
return;
[plays_predicate_editor reloadCriteria];
[ NSApp beginSheet:filter_window modalForWindow: main_window

}
I have greatly simplified my predicate and I still get the exception. If I
comment out the call to reloadCriteria the predicate editor is correctly
displayed with the default values setup in IB.
What is the log message trying to tell me?. What strategies and tools can I
use to debug such a problem?
Thank you for the help.

Localization.strings in UTF16 vs UTF8
Anyone know of any reasonable explanation why for Cocoa localization files need to be in UTF16? http://developer.apple.com/mac/library/documentation/MacOSX/Conceptual/BPInternational/Articles/StringsFiles.html#//apple_ref/doc/uid/2005-SW1 Is this just to make using SCMs painful?

On 15 dec 2009, at 07.47, Torsten Curdt wrote: Anyone know of any reasonable explanation why for Cocoa localization files need to be in UTF16? Hello Torsten, I think that this is simply a documentation bug. Cocoa expects, or at least expected, strings files in the product to be UTF16. For that reason, the recommendation was for you to maintain your strings files as UTF16. Recent versions of Xcode (both 3.1.x and 3.2.x) will convert your strings files to UTF16 automatically as they are copied over to the build product, allowing you to maintain the source version of the strings file in the more manageable UTF8. It's easy to change the encoding of your strings files by using the file inspector in Xcode. You'll also find that when you create new projects / files in Xcode, strings files are provided as UTF8 out of the box. You can find snippets of information about this in the Xcode release notes: http://developer.apple.com/mac/library/releasenotes/DeveloperTools/RN-Xcode/index.html Please file a bug report on any documentation that you find that isn't updated: http://developer.apple.com/bugreporter/ Thanks, j o a r ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Just consider this code alone (I've moved everything into the view's controller): UIScrollView* sv = (UIScrollView*)self.view; CGRect f = self.view.bounds; sv.contentSize = CGSizeMake(f.size.height * 2.0, f.size.width); Now, what I'm trying to do is make the content twice as *wide* as the scroll view, so that I page from side to side, in this landscape-oriented app. And I am succeeding in doing so!

Don't use Reachability synchronously. At some point you will be blocked, you will hit a watchdog timer, and your application will be killed. The current reachability sample correctly demonstrates how to use Reachability asynchronously, but most importantly it continuously updates you on the current state of the network, so you can properly adapt to changes (such as when the train the user is on goes into a tunnel and the network goes down). In your particular case, it would allow you to disable or hide the button when the network is down, rather than displaying an alert when the user tries to use it.

But that means the difference should not really matter here then. You are correct. The problem here is not because of using @executable_path instead of @loader_path. The problem is because the binary was moved outside of Contents/MacOS where it belongs. Well, those user will not go into the package and will move the bundle resources around (from what I read from the reports they don't even have a clue what a bundle is ;) Right now I suspect the unzipping of the app to be a problem or something.

Ideas for multi-type inspector design
Hi All, I am trying to make an inspector like panel for my application and could use some input on the design of that. My application has an NSOutlineView displaying objects of multiple types. These objects are stored in an NSTreeController. Now, I would like to have an inspector panel show some attributes for the object selected in this NSOutlineView. The set ob attributes to be displayed/made editable via the inspector depends on the type of object selected - essentailly the same as e.g. InterfaceBuilder is doing when different elements in a NIB file is selected. I am able to get the infrastructure of the inspector up and running and also able to make a NIB file and an NSWindowController subclass for each object type to go into the inspector. Where I need some input is on how to determine which of these controllers are activated when the selection in the OutlineView changes so that the correct NIB can be swapped into the inspector window ? - One solution is to hold a dictionary mapping some kind of type-id to the appropriate WindowController-pointer. Surely this is not a nice solution as this dict must be changed when new types are created in later versions of the app - either manually or by a bundle-loading-like approach. -Also, the dataobjects should not know about their respective inspector-panel/controller as this will violate the MVC pattern.

MATCHES can be used (it seems to act like NSLiteralSearch) but it is quite slow.

NSComparisonPredicate Class Reference mentions under NSComparisonPredicate

I just tried it: BEGINSWITH[n] finds that กิน begins with ก - same as

Re: Sorted Table Column

When I click on the NSTableHeaderView a triangle appears and now the items are nicely sorted. Is it possible (either in InterfaceBuilder or programmatically) to make the NSTableColumn start with this sorted behaviour? In your -awakeFromNib method, pass the sortDescriptors from the table view to the array controller. I think I got that wrong Actually, that's what I do, and it works well. You can set up sort properties in IB on a tablecolumn but not on an array controller. On the tablecolumn, I'll set the 'sort key' attribute and the 'selector' attribute (to localizedStandardCompare:, if you support 10.6+) then in my windowcontroller's awakeFromNib I set the arraycontroller's sort descriptor by fetching the tableview's. -- Sean McBride, B.

(Sometimes I get the error sooner). The error is happening in [NSMenu _enableItem:]. Is there some other menu item that has to be hooked up to something?

The scroll view *is* rotated (i.e. I'm not merely holding the iPhone sideways; things drawn in the scroll view in IB with the view rotated are appearing correctly in the running app) so shouldn't width mean width? My code works perfectly, I just want to understand why. Does rotation not really mean rotation? Am I supposed to manually apply a coordinate transform that the docs have failed to warn me about?

Core Data and pre loading objects (importing).
Hi, I am pretty new to cocoa so thanks for being patient... I have spent some time building a command line tool that reads a .txt file saved locally by an online poker client. This file contains data on my own playing history. I have a chunky method that dissects this file and creates different objects of type Tournament, Table, Player, Hand, Card etc and works well. Having accomplished this, I set about trying to build a core data app to display the data. I have replicated my model exactly as it is in the original project and successfully set bindings etc. For example, I can create, edit and remove players. But I am entirely stuck on how to join the two projects. All I really want to do is use the method I already have to populate the core data application, but despite hours of searching I don't know where or how to start. I have been able to programmatically create new players using: NSManagedObject *player = [NSEntityDescription insertNewObjectForEntityForName:@Player inManagedObjectContext:[self managedObjectContext]]; I have put this in the init of MyDocument and it creates and dsiplays the player (via the binding) as expected. But what I want to do is use a tournament builder class from the original project that takes in a filepath and returns a Tournament, complete with all it's players, tables etc. This function works well in the original project but when I try to use it in the core data project I get: Failed to call designated initializer on NSManagedObject class 'Tournament' All of my classes have created by xcode and inherit from NSManagedObject. I have then replaced the contents of each .m file with the original classes. I know I'm doing something horribly wrong here, so my question is this... How am I meant to load into core data a whole graph of objects (tournament and its constituent parts) that are returned from a function, and where should I be putting the code?

Re: NSNumber stringValue
on Sat, Dec 12, 2009 Andy Lee may have said: As glenn pointed out, that string most certainly *can* be a string that can be converted back to a bitwise equivalent of the original float. Ben's question was whether in practice it is guaranteed to be so, or whether stringValue uses a maximum number of decimal places that would lead to rounding error. I can't tell from a quick look at the docs. A float is 32 bits, so it can not represent in exact bits every integer value, not to mention decimal places. Thus while a string can be converted back to a bitwise equivalent of the original float, there is no guarantee that it will be. Also, keep in mind that internally Apple represents many values as doubles. Thus some of the examples in the discussion, such as: whether going out to the stringValue and back to the doubleValue is guaranteed to yield a float that is bitwise identical to the original float are giving up 32 bits of precision for no reason. If you start with a NSNumber, write that out as a string, then read it back in as a string, convert back to an NSNumber, and then get that value as a float you are not only converting the value back and forth between binary and string representations, but also from 64bit to 32bit representations. The binary conversion is likely to loose more precision than the string conversions. If you are starting with a value that can be represented as a double, keep it in that format. Unless you are on a mobile device, GPU code or other specialty code the use of doubles is not costly enough to worry about and it gives you much better precision during calculations as well as better retention when converting back and forth between string and binary representations.

Core Data - Importing using NSOperation - Problems on main thread
Hi, I have an application that persists its data using core data. It uses an NSOperation to download new versions of the data asynchronously. This NSOperation uses its own MOC (moc2) (as opposed to the MOC (moc1) used in the main thread, which is used by the UI). Both MOCs share the same persistent store which, as I understand it, this is the paradigm recommended by Apple (for using Core with multiple threads). My problem occurs when the NSOperation is almost complete and deletes all the old Managed Objects (that have been replaced by the new data) performs a [managedObjectContext save:error] with the intent of making the new data available in the other MOC (moc1). The old data is deleted using [managedObjectContext deleteObject:objectToDelete] after the new data has been added. At the same point in time as the update is taking place, the user may be scrolling through the data in a UITableView (using custom cells populated with data from managed objects in the main thread MOC moc1)). The heavy lifting is performed by a NSFetchedResultsController - using code similar to that in the Apple CoreDataBooks example There are a number of problems with this approach If the user happens to select the view causing the fetched results controller to be initialised i.e. [self.fetchedResultsController performFetch: error] whilst the NSOperation is deleting the old Managed Objects, and attempts to scroll an exception is thrown in cellForRowAtIndexPath (as the object that it is referring to has just been deleted) Problems also occur in the fetched results controller delegate methods, where the didChangeObject methods gets called with NSFetchedResultsChangeUpdate instead of NSFetchedResultsChangeDelete if the user is scrolling up and down the list at the same time (though everything works if the user is not scrolling). Any ideas on how I can avoid these problems, or come up with a more elegant solution? -- NB ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Smooth Scrolling for NSScrollView
There was a smooth scrolling feature that was introduced in 10.3 which seems to be automatically enabled for NSTextViews, but it doesn't seem to work for NSScrollViews with custom views. Is there anything I need to do to enable this? Or is this enabled by default now (I'm using the 10.5 SDK, running 10.6)? Just wanted to make sure because my scrolling certainly does not feel smooth. Looked up documentation on how to do this, but found nothing. I don't kow about NSScrollViews but with the Apple mouse with the little scrolling ball, and with two finger track pad scrolling, scrolling is perfectly smooth because of the fine resolution. 'Smooth scrolling' which tried to filter the large steps of the old clicking scroll wheels, seems obsolete. Somehow Opera hasn't got the message. It still scrolls in steps, even with track pad scrolling. TextEdit has an odd behavior too: When jumping to the top or bottom of a large file it seems to coast in with smooth scrolling and go instantly without it, which I much prefer. - Bill Ehrich ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Everything works, but the mouse pointer acts not very smooth. Means that it feels like the mouse always is behind the finger and sometimes it even sticks for a while.

Ideas for multi-type inspector design
Hi All, I am trying to make an inspector like panel for my application and could use some input on the design of that. My application has an NSOutlineView displaying objects of multiple types. These objects are stored in an NSTreeController. Now, I would like to have an inspector panel show some attributes for the object selected in this NSOutlineView. The set ob attributes to be displayed/made editable via the inspector depends on the type of object selected - essentailly the same as e.g. InterfaceBuilder is doing when different elements in a NIB file is selected. I am able to get the infrastructure of the inspector up and running and also able to make a NIB file and an NSWindowController subclass for each object type to go into the inspector. Where I need some input is on how to determine which of these controllers are activated when the selection in the OutlineView changes so that the correct NIB can be swapped into the inspector window ? - One solution is to hold a dictionary mapping some kind of type-id to the appropriate WindowController-pointer. Surely this is not a nice solution as this dict must be changed when new types are created in later versions of the app - either manually or by a bundle-loading-like approach. -Also, the dataobjects should not know about their respective inspector-panel/controller as this will violate the MVC pattern. Any ideas or thougts are greatly appreciated. Thanks, Mads ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Surely this is not a nice solution as this dict must be changed when new types are created in later versions of the app - either manually or by a bundle-loading-like approach. -Also, the dataobjects should not know about their respective inspector-panel/controller as this will violate the MVC pattern. Any ideas or thougts are greatly appreciated. I've done this using a naming convention of my own devising, based on the classname. So you could get the object's class, convert it to a string using NSStringFromClass(), append some other stuff if you want and look that up as the nib name. It's extensible without coding changes, though you'll probably want to build in some protection against having the nib not found and so on. Also, some simple protocol (or base class) shared by all the loaded controllers will allow the loader to treat them all equally, in terms of getting the view to be installed in the window and passing the object to be inspected to it. --Graham ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: NSUndoManager issues
On 15/12/2009, at 1:02 PM, Scott Squires wrote: I have some image processing routines that are on another thread and undo objects are created. When these are done in a series by the user (several minutes apart) and an undo is preformed then one by one they are invoked from just one undo request. The inverse is true for redo. The non-threaded items work as expected. if a non-threaded item is done after a threaded item then it all works correctly. Is there a reason for this and how do I make sure each undo action from the user only causes one undo step to be preformed? I haven't experimented with Undo from another thread, but I suspect that's going to be awkward, if it's even allowed. On the main thread, an undo group is automatically opened by the first task submitted to the undo manager and closed at the end of the event cycle, unless -setGroupsByEvent: is NO. Undo tasks submitted from a thread will be completely out of synch with this mechanism, so you'll find groups not being correctly formed - the opened group will be closed on the main thread regardless, I think, so they'll be closed at arbitrary points relative to the execution of the thread. You should probably arrange for the thread to submit its undo tasks to the undo manager on the main thread, and give some thought to managing the groups manually. At that point you'll probably start to run into the numerous bugs and glitches that NSUndoManager suffers from, and start to tear out your hair.

Managed Object with Transformable Attribute (C Struct)
I have a managed object with a transformable attribute. The attribute
is a C struct and uses a custom value transformer. The transformer
uses the depreciated NSArchiver but it is drop dead simple and it works.
I am trying to implement keyed archiving and can't figure out what to
do or which way to go. I can't seem to see the forest for the trees
and keep going around in circles in the documentation and on the web.
The C struct Foo is defined like this.
typedef struct { double a; double b; double c; double d; } Bar;
typedef struct { Bar e; Bar f; } Foo;
The current custom value transformer.
@interface MyArchiveToDataTransformer : NSValueTransformer
@end
@implementation MyArchiveToDataTransformer
+ (Class)transformedValueClass
{
return [NSData class];
}
+ (BOOL)allowsReverseTransformation
{
return YES;
}
- (id)transformedValue:(id)value
{
return [NSArchiver archivedDataWithRootObject:value];
}
- (id)reverseTransformedValue:(id)data
{
return [NSUnarchiver unarchiveObjectWithData:data];
}
@end
Any suggestions or insight for the lost and confused?

Dirtying NSSearchField
I have a document based Core Date app. MyDocument.nib contains among other things an NSSearchField (or NSTextField - same behaviour) which has it's value bound to some NSString in MyDocument.h. When I type in this SearchField the window gets marked as dirty (documentEdited) and the Edit menu has an item Undo Typing. When I click somewhere else (so that the SearchField loosed it's blue focus ring) the window becomes clean again and the Edit → Undo menu item is disabled (light gray). The problem: when I type in the SearchField and then close the (now dirty) window, a panel comes up with: Do you want so save ... your changes will be lost otherwise ..., which I find extremely confusing, as the real data have NOT been changed at all. Also: Undo for a SearchField is not really a necessary feature. I unselected in InterfaceBuilder the Allows Undo for my NSSearchFieldCell. Now no more Undo Typing in the Edit menu, but still the window gets marked as documentEdited. So how to make the NSSearchField refrain from messing with the documentEdited status of my window? 10.6.2 Kind regards, Gerriet. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Set the slider's minimum value to 0.5? One octave is a factor of two - going up doubles the pitch (frequency), going down halves it. If you multiplied the frequency by 0.0 it would become 0, not half its original value. If you want the slider to operate as a linear control with 1.0 in the centre, you'll have to apply an offset and scale factor to its value externally to get the geometric range change needed. --Graham ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: App works when launched from Xcode, not from Finder
Here's the screen capture that demonstrates this issue: http://www.vimeo.com/8208563 This time around, I got a few errors logged in Console: *** -[NSRecursiveLock unlock]: lock (NSRecursiveLock: 0x16c2340 '(null)') unlocked from thread which did not lock it *** Break on _NSLockError() to debug. *** -[NSRecursiveLock unlock]: lock (NSRecursiveLock: 0x16c2340 '(null)') unlocked when not locked *** Break on _NSLockError() to debug. *** -[NSRecursiveLock finalize]: lock (NSRecursiveLock: 0x16c2340 '(null)') finalized while still in use *** Break on _NSLockError() to debug. *** -[NSRecursiveLock finalize]: lock (NSRecursiveLock: 0x16ca9c0 '(null)') finalized while still in use *** Break on _NSLockError() to debug. I've gotten these before, and they don't seem to affect the operation of the app so I doubt this is what's causing my problem, however I have set a breakpoint on _NSLockError to catch this next time (It happens randomly, not all the time). In the meanwhile, I directly launched the apps executable using Terminal, and here is the error it logs: fail: 'Error Domain=NSURLErrorDomain Code=-1012 UserInfo=0x2004dad80 The operation couldn’t be completed. (NSURLErrorDomain error -1012.) Underlying Error=(Error Domain=kCFErrorDomainCFNetwork Code=-1012 UserInfo=0x2004dad00 The operation couldn’t be completed. (kCFErrorDomainCFNetwork error -1012.))' This would explain my apps screwup. If it can't connect then that would explain the request timed out and authentication errors. The problem is, I have no idea why this only happens on the Release config *when launched from Finder* And I don't know how to debug this, as this problem doesn't occur when the app is launched by Xcode. Is there a way to load an executable into gdb manually?

I don't think its an issue with my code if it works in Debug (Xcode Finder) and Release (Xcode only). Two rules of software development: Rule 1: Check again. It's probably your fault. Rule 2: It's still probably your fault. My build configurations for both Debug and Release are identical (I haven't checked thoroughly, but I know I didnt change much). Both configs are set to use the LLVM GCC 4.2 compiler, and GC is set to Required. The only other change I've made is adding a few header search paths. When it comes to debugging, there is no such thing as not checking thoroughly. There is only Checking thoroughly and not checking at all. Checking thoroughly means proving (not convincing, but actually sitting down with a backtraces, a debugger, and even single-stepping through your source code if necessary) that your program is behaving as designed. So, run your release-built app from inside gdb (yes, you can run a non-debug app inside a debugger). When it does something wrong, trap that error in the debugger and figure out what happened.

So I don't understand what you mean by an archive-within-an-archive. Sorry if this is a dumb question. Ah, I think I'd misunderstood something - I thought you were archiving a bunch of objects for file saving, which would not archive your struct, so you were archiving the struct to a separate piece of data which could be archived. Hence archive-within-an-archive. What you actually have is an archive-within-a-core-data-store. I don't have any experience of Core Data so I don't know how it represents itself on disk, but I sort of gather that it will use one of: sqlite store, archive (binary) or archive (XML). If either of the latter you do have an archive-within-an-archive, it's just that the main archive is built and written by Core Data. I was trying to emulate what Apple does with NSRect, NSSize, NSPoint, etc. I thought if Apple can get the Cocoa frameworks to work with simple structs then why can't I. Because there are special conversion functions such as NSStringFromRect(), etc which are used when archiving, so in fact the structs are stored as strings. My struct 'Foo' really wants to be a struct not a class, I think. It is used in a lot of heavy duty math calculations and functions but I also need to save it to the persistent store. Making it an object wouldn't necessarily impact on that. You could return the struct itself as a property or just implement the math as methods of the Foo class. But it's up to you - as a naked struct it will be a poor cousin to a first-class object when it comes to all sorts of handy things, such as memory management, collections and archiving.
