Re: How can I be so wrong about graphics?
Hmm... it looks like it does draw the line... way off in the ether somewhere... I think I drew in the global coord system not the local to the view Are you sure you are _not_ calling drawRect yourself, but let the system call it when needed? If a view needs to be redrawn, the system sets up the correct graphics context, coordinate system transformations etc. and then calls drawRect. If you call drawRect yourself (what you should never do!), you end up drawing into somewhere.

Re: iOS: Manually setting orientation makes a mess out of my interface
It might be the wrong way to set the orientation manually?

Noob question in regards to NSXMLParser
I am fetching some XML weather from Google:

What I am really after is the current_conditions data. How can one specify
WHERE in the XML to use the attributes from? A lot of the information is
repeated in other nodes so I can't just check (if([elementName

within a specific tag? (In this case the parent is current_conditions)?

Re: Noob question in regards to NSXMLParser
Two ways that I've used:
1. Keep a boolean isInCurrentConditions that you set when you start the
current_conditions element and reset when you end that element. Then every time
you enter a condition element you check the boolean to see if you are where you
need to be in the hierarchy. This works well enough if your hierarchy is not
too complicated and you only need to know about a couple of elements. If it
does get complicated, you'll end up tracking a dozen booleans, which I don't
recommend.
2. The complicated case: keep a stack of element names. Every time you enter
one, you push it, and every time you leave you pop it (it pays to check what
you're popping, just in case). Then, whenever you encounter a condition
element, you check the stack to see if you're at the right place in the
hierarchy.
I'm sure there are other ways, but these have worked well for me.
Hope this helps,
Hank

I went with the first solution and it works well enough for me. Anything
beyond this simple XML and I think I'd likely use a 3rd-party solution.

seeking to understand ABPeoplePickerView behavior
I have been trying to implement setNameDoubleAction: setGroupDoubleAction:
which I do in applicationDidFinishLaunching as follows:
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
stuff
[pickerView setNameDoubleAction:@selector(doNameSelection:)];
[pickerView setGroupDoubleAction:@selector(doGroupSelection:)];
}
Allows Multiple Selection, Allows Group Selection, Multiple Value Selection
are set for the picker in IB. Everything wired up, classes included,
nameDoubleAction works fine. So does groupDoubleAction but only when I choose
All Contacts or more than 1 group. Choosing only 1 group (other than ll
Contacts) always results in Abe[2333:903] Controller cannot be nil. However,
this never occurs when I double click a single name!
Apple literature has been less than helpful in this so I have searched the web.
I finally found an example at
http://pommedev.mediabox.fr/utilisation-des-classes-cocoa/abpeoplepickerview-un-bug-dans-l'api/
which suggested using [pickerView setTarget:self]; So…
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
//NSApplicationDelegate
{
stuff
[pickerView setTarget:self];
[pickerView setNameDoubleAction:@selector(doNameSelection:)];
[pickerView setGroupDoubleAction:@selector(doGroupSelection:)];
}
works like a charm!
Ok, it's running but I can't understand why this is needed for the
groupDoubleAction but not the nameDoubleAction. Any hints or suggestions as to
this behavior?

You _totally_ want to use XPath for this. It lets you write a simple query
string that fetches arbitrarily nested data. What you’re asking for is a
one-liner. There is a little bit of a learning curve for learning the syntax,
but it’s really worth it (you can find online tutorials pretty easily by
searching.)
So instead of NSXMLParser, use the higher level NSXMLDocument (which can even
fetch the URL for you) and then use the XPath methods on it.
[Um, except now it occurs to me that you didn’t specify what OS you’re on, and
last I heard iOS didn’t have NSXMLDocument yet… If you’re using iOS, it’s best
to specify that explicitly, since a lot of us old crusties here will assume OS
X unless otherwise stated.]

Re: CoreData problem - AttributeDescription seems invalid --- What am I doing wrong?
Thanks everyone. I knew it had to be something stupid
I still feel that iterating over a dictionary means iterating over its
CONTENTS, not its KEYS --- but that's just my weird brain. Finally I found it
in the documentation as well.
Following Evadne Wu's advice it now works flawlessly.

Hello Motti,
I believe -attributesByName returns a dictionary, where the keys are names
(NSStrings) and the objects are NSAttributeDescription objects, so when you
say `for (id something in aDictionary)` that `something` is going to be the
key, not the object value [1], and you will just get the attribute
description by using that key.
This *might* work:
- (NSMutableDictionary *)attributesAsDictionary {
NSDictionary *attributesByName = self.entity.attributesByName
NSMutableDictionary *returned = [NSMutableDictionary
dictionaryWithCapacity:[attributesByName count]];
for (NSString *aKey in [attributesByName allKeys]) {
[returned setValue:[self valueForKey:aKey] forKey:aKey]; // nil allowed if
my memory stands
}
return returned;
}
[1]: I believe you’ve assumed that for…in enumerates object values for
NSDictionary objects?

Hello everyone.
We work with a CoreData model that is memory-based. However, at times I
would want to (partially) save an entity to the UserDefaults, as a
dictionary. For that, I wrote a little NSManagedObject extension (Category)
with the following method:
@interface NSManagedObject (OURExtension)
@property (readonly) NSMutableDictionary *attributesAsDictionary;
@end
- (NSMutableDictionary *)attributesAsDictionary {
NSMutableDictionary *attributesDictionary = [NSMutableDictionary
dictionaryWithCapacity:[self.entity.attributesByName count]];
for (NSAttributeDescription* attribute in self.entity.attributesByName
) {
NSString *attribName = [attribute name];
id attribValue = [self valueForKey:attribName];
if (attribName attribValue)
[attributesDictionary setObject:attribValue
forKey:attribName];
}
return attributesDictionary;
}
Running the method for a nice entity that I just Saved (validated) and
Fetched again (to be sure it's in the store) --- the method crashes horribly
on the NSString *attribName = [attribute name];
If I step inside with the debugger, I see things I can't understand. I get
into the loop, and for the first attribute ---
1. Debugger claims 'attribute's type is CFStringRef * instead of
NSAttributeDescription*
2. Summary for attribute is telephoneID which is reasonable --- one of my
attributes is named like that.
3. drilling down, the private _name iVar for the attribute is nil but
when I try to get it :
4. NSString *attribName = [attribute name] crashes and debugger looses all
track of stack or anything.
I looked for valid isValid or similar properties in
NSAttributeDescription and its ancestor NSPropertyDescription to no avail.
Nothing in the docs will tell me WHEN is it right to use the
NSAttributeDescription in the above manner.
Ideas anyone?

I am sending a URL string to NSWorkspace's openURL method that has the bracket characters ( ) in it. The URL can't be opened by NSWorkspace. If I take out the ( ) characters NSWorkspace then opens the URL, so I guess NSWorkspace considers the string with ( ) a malformed URL.

This bug occurred when using the LSSharedFileList API; I'm not sure about the checkbox in System Preferences. Anyhow the Bug ID number was 5901742.

Not related to Cocoa -- but It turns out after playing around with this with mapquest and google maps, adding a label can change the view that you get (particularly in google maps). So I probably won't add that. But at least I found out how to get a legal URL string in the process.

Determining bounds needed for a Core Image effect
I'm using Core Image filters to apply real-time effects to vector objects. I've run into the problem of determining just how much space I need to accommodate any given effect. Currently I just add a fixed percentage to the bounds I start with, but it's actually inadequate to do this for many effects, which frequently end up running off the edges of the space allotted. The vector objects have a defined bounds which fully encloses all drawing that they do. When these objects are altered, that bounds is used to refresh just that part of the view as needed. When a CI Filter is applied, I use that bounds, multiply it by some scaling factor, and use that to create an offscreen image into which the vector object plus its CI effect is rendered. The resulting image is then drawn in the view. The needed space for a given effect varies depending on the effect and its parameters, but I see no way to compute that reliably. If I make the bounds some enormous scale-up of the original bounds to accommodate any potential effect, performance suffers dramatically because of all the wasted area of the view that has to be updated. Is there any way to preflight a Core Image filter effect so I know how much space I'll need to draw it? --Graham ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
