why LSSharedFileListInsertItemURL function can't work?
Hi all, In my code below i used LS functions to do something, but i can't get the result what i wanted. Somebody can tell me which i missed ? thank you! First I generate a IconRef variable and used in LSSharedFileListInsertItemURL(): IconRef iconRef = NULL; CFURLRef tCFURLRef = CFBundleCopyResourceURL( myCFBundleRef, CFSTR( Application ), CFSTR( icns ), NULL ); status = RegisterIconRefFromFSRef( '', 'icns', tFSRef, iconRef ); LSSharedFileListItemRef item = LSSharedFileListInsertItemURL(favorite_items, kLSSharedFileListItemBeforeFirst, CFSTR(), iconRef, (__bridge CFURLRef)url, NULL, NULL); The result is insert a item to Finder slider, but the item icon does not showing what i specified. what's wrong? And the code below does not take effective too. OSStatus er = LSSharedFileListItemSetProperty( item, kLSItemDisplayName, CFTypeRef(CFSTR(some title))); thanks again. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

MacOS: Selecting from Multiple tables in the same window
In MacOS 10.8 I have a window that contains two NSTableViews
clipListTable and
tablesTable
In the data model. tablesTable has a to-many relationship with the selection of
clipListTable
In the window controller awakeFromNib I set the window controller to be the
delegate of the two tables
- (void) awakeFromNib
{
[super awakeFromNib];
[[self tablesTable] setDelegate:self];
[[self clipListTable] setDelegate:self];
}
The window controller has a delegate procedure tableViewSelectionDidChange:
#pragma mark - NSTableViewDelegate methods
- (void)tableViewSelectionDidChange:(NSNotification *)aNotification
{
id tableCandidate;
tableCandidate = [aNotification object];
DLog(@ tableCandidate %@, tableCandidate);
DLog(@ clipListTable %@, [self clipListTable]);
DLog(@ tablesTable %@, [self tablesTable]);
if (tableCandidate == [self clipListTable]) { //Change in
clipListTable
NSArray *selectedObjects = [[self videoClipArrayController]
selectedObjects];
if ([selectedObjects count] == 1) {
VideoClip *clip = [selectedObjects lastObject];// There should
only be one...always.
}
}
else if (tableCandidate == [self tablesTable]) {//Change in
tablesTable
NSArray *selectedObjects = [[self tableArrayController]
selectedObjects];
if ([selectedObjects count] == 1) {
Table *tab = [selectedObjects lastObject];// There should only be
one...always.
}
}
}
If i select a row in the clipListTable, the log reads:
2012-11-17 10:29:38.760 Roboplasm[82172:303] -[MediaWindowController
tableViewSelectionDidChange:] tableCandidate NSTableView: 0x1006f20b0
2012-11-17 10:29:39.727 Roboplasm[82172:303] -[MediaWindowController
tableViewSelectionDidChange:] clipListTable NSTableView: 0x105407260
2012-11-17 10:29:48.089 Roboplasm[82172:303] -[MediaWindowController
tableViewSelectionDidChange:] tablesTable NSTableView: 0x1006f20b0
and the Change in tablesTable branch gets executed
If I select a row in the tablesTable, the log reads
2012-11-17 10:32:29.463 Roboplasm[82172:303] -[MediaWindowController
tableViewSelectionDidChange:] tableCandidate NSTableView: 0x1006f20b0
2012-11-17 10:32:30.131 Roboplasm[82172:303] -[MediaWindowController
tableViewSelectionDidChange:] clipListTable NSTableView: 0x105407260
2012-11-17 10:32:30.807 Roboplasm[82172:303] -[MediaWindowController
tableViewSelectionDidChange:] tablesTable NSTableView: 0x1006f20b0
and the Change in tablesTable branch also gets gets executed. In other words
aNotification always reports the tablesTable as the tableCandidate no matter
what table i click on in the window.
How can I respond to a selection in the clipList Table?

Re: Dumb question about unit testing
In other words, you bootstrapped the process, right? You generated a class that had encodeWithCoder:, wrote out the results, then went back and coded initWithCoder:, using the written out stuff to pull it back in? That's what I was thinking, too. I was just wondering if there was some way to make an app that could create/edit these saved objects directly at the binary level so I could make sure of the intermediate results from option #1! Otherwise, if the test failed, how would you know which half failed, the initWithCoder: part, or the encodeWithCoder: part? I think I'll do #2. Thanks for the help!

Re: Notification for if User changes Finder Label on File
You can use the libdispatch to monitor file changes (using DISPATCH_SOURCE_TYPE_VNODE). You can also use a kqueue to look for change on a specific file. If you want a Cocoa wrapper, there is the well known UKKQueue class available on the net. Both solutions are far more efficient if you have to monitor only a couple of files.

Could you clarify what you mean by supposedly, this works? If the documentation says you can't do it, then Apple does not suppose it works, and Apple is the only one whose suppositions matter. At one time, you liked the undocumented behavior you got, but that doesn't guarantee Apple will always deliver it. The documentation of this method for the collection classes explicitly forbids the use of nil. The documentation for NSKeyValueObserving forbids it only implicitly: nil can't be a relative key path that the observer has registered. If it were permitted, the documentation would say what the method would do if you passed nil. I assume that means the use of nil is undefined at best, and they forgot to say so.

enhancing NSTextView for optionally-hidden text
NSTextView does exactly what I need in my apps non-editable text view which functions something like a log, except for one needed function which I can best envision in the form of a text attribute hidden, akin to hidden text features I used to use in the *past* in MS Word, in which it was possible to select a document-wide option to show or hide hidden text. (This was something I did in Word pre-OSX. I can not see a way to show hidden text in the currrent Word that I have from Office 2008. The current version still has a hidden attribute and permits including hidden text when printing. Word for all I know may not use any native OSX text functionality, so it may not be very indicative of what to expect is possible.) In any case what I want is a hidden attribute which can be enabled/disabled for an entire text view. I can not find any such functionality in the NSTextView documentation, nor any hint of it in the standard text attributes. Given how this view is used, for appending only in the style of an uneditable text log permitting user selections and Copy, the easiest way I can think to implement it is to maintain two text views, one with hidden text included, and one without, and simply swap the two views to implement show/hide of hidden text. Is there a better way? I would rather not get deep into a highly-structured text document kind of model in order to achieve something like this (assuming that even helps). -Kurt Bigler ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Can't seem to present modal storyboard scene
Hi. I've got a part of my storyboard that has a UINavigationController and a UIViewController in that. It's triggered by tapping a button with a modal segue. But I also want to display it sometimes at application start (it's release notes). So, I do this: UIStoryboard* sb = [UIStoryboard storyboardWithName: @MainStoryboard bundle: nil]; UINavigationController* nc = (UINavigationController*) [sb instantiateViewControllerWithIdentifier: @releaseNotes]; ReleaseNotesController* controller = [nc.viewControllers objectAtIndex: 0]; controller.delegate = self; [self.window.rootViewController presentModalViewController: nc animated: true]; All the controllers come back with good values, and are the right class. But nothing ever shows up. The rootViewController is a tab bar controller, and it does show up. Is there something I'm missing?

Thanks Ken, it allows me to file duplicates for them to show Apple we care. You're welcome, but it almost seems better to me that you file an original bug report without reference to the duplicate. The Apple folks are more likely to evaluate your report on its own, rather than simply thinking to themselves Oh, this is already known to be a duplicate. Set its status as such and stop reading. Perhaps, on considering your specific report, they might not deem it an exact duplicate for some reason. Given the relative vagueness of our discussion here, maybe we're talking about two separate but related things. Even if they do determine it's a duplicate, they had to spend more time considering the issue before deciding that, so I suspect it accumulates additional weight in their consciousness. That is, your vote will count for more. But that's all speculation about other people's psychology, so not worth much.

Is there a better way? I would rather not get deep into a highly-structured text document kind of model in order to achieve something like this (assuming that even helps). Perhaps better than two views would be two attributed string properties (of the object that knows when the log changes). In one, you'd either mark the hideable text with the (unique?) attribute that indicates the hideability in the display, or with an custom attribute. One string property would return the whole attributed string. The other would be a derived property that takes the whole string, and constructs a display string which in turn is either the same whole string (if hideable text is turned on) or a reduced string (if not, by enumerating the attributes). Assuming you took care to make the derived property KVO-compliant, then you could simply bind the text field to the derived property. This may not sound like an improvement on your original idea, but it centralizes the necessary code (in the whole string setter, perhaps), and avoids the IB awkwardness of superimposed views. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
