Re: Binding NSTableView to NSSet
Op 14 jul 2012, om 04:46 heeft Koen van der Drift het volgende geschreven: A follow up question: how do I now sort the data in the table? I am showing three values in the table, and like to sort based on either one of them. The original data is in an unordered NSSet (from my CD model). I could create an NSArray in my view controller: NSArray *myArray = [myTagsSet allObjects], and bind that to the NSArrayController, instead of to the NSSet; then I can sort the values in the table based on the array using sortDescriptors as explained here: https://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/TableView/SortingTableViews/SortingTableViews.html#//apple_ref/doc/uid/1026i-CH10-SW1. Would that be a good approach? Other alternatives? Can't you just set the sortDescriptors of the array controller?

Sandbox Unit Testing
Hello, I have an app that is sandboxed that I want to perform some unit testing with. When I run the test, I get something like: no suitable image found... open() failed with errno=1 IDEBundleInjection.c: Error loading bundle ' When I turn off Entitlements in the application target's Summary then the test performs as expected. Is there some magic sauce I can add to this, so that I can run the unit tests while sandboxed?

Re: Core Data book for OSX
Koen, CoreData for iOS and Mac are mostly the same, but the biggest difference is that iOS doesn't support bindings. Bindings are important and for that reason I don't think that an iOS Core Data book would be sufficient for you. I recommend Cocoa Programming: A Quick-Start Guide for Developers by Daniel H Steinberg. The book is aimed at experienced programmers who are new to Cocoa. It only supports Xcode 3, but I don't think that's a problem. Specifically, I would read chapters 19-Key Value Coding, 20-Key Value Observing, 21-Cocoa Bindings and 22-Core Data. Supplement this with reading Apple documentation which is referred to in the book. http://pragprog.com/book/dscpq/cocoa-programming The Pragmatic web site says that it's out of print, but I found it on Amazon: http://www.amazon.com/Cocoa-Programming-Quick-Start-Developers-Programmers /dp/1934356301/ Also, stackoverflow.com can be a good resource: http://stackoverflow.com/questions/tagged/core-data And I've found Tim Isted's blog to be useful. I was just reviewing this post on Multiple Windows with Core Data. It's from July, 2008 so parts of it may be out of date. http://www.timisted.net/blog/archive/multiple-windows-with-core-data/ Chuck On 7/14/12 5:06 AM, Koen van der Drift koenvanderdr...@gmail.com wrote: I really want to learn more about CoreData on the Mac and am looking to get a book, besides the Apple docs. I already get the basics, but there are still many things that make me scratch my head. Often recommended is the book by Marcus Zarra, but this is out of print, and I wouldn't be surprised if they are working on an update, but no idea when that's going to be on the market. Is it still relevant, or already outdated when using (M)Lion? I can find a copy through Abebooks if needed. Or am I better off getting a more recent book about CoreData for iOS (there are several on the market, e.g. Imsted Harrington)? I would guess that in the core (no pun) it is the same for OSX and iOS, so I may go that route. Or is a book about CoreData on iOS completely useless when developing for OSX?

CA crossfade
10.7 SDK, 10.7 target. The content view of the window is layer-hosting,
containing only a CALayer.
I'm trying to crossfade the contents image of the CALayer from Image A (the
existing contents) to Image B (the new contents). Surely this is simple. I'm
thrashing.
Here is an excerpt from my controller object's set-image method. I've seen the
following code (more or less) in responses on the Web, and it has always met
with apparent satisfaction, but it does not work as I intend: Image A is
instantly replaced by Image B, then the crossfade from A to B runs. Image B
remains.
=
// Initialize nsImage with the new contents.
CABasicAnimation * crossfade;
crossfade = [CABasicAnimation animationWithKeyPath: @contents];
crossfade.duration = 0.75;
crossfade.removedOnCompletion = YES;
crossfade.fromValue = self.backgroundLayer.contents;
crossfade.toValue = nsImage;
[self.backgroundLayer addAnimation: crossfade forKey: nil];
self.backgroundLayer.contents = nsImage;
=
Commenting-out the assignments to .fromValue and .toValue yields the same
effect.
Okay, try this: add
crossfade.delegate = self;
before the addAnimation:, and delete
self.backgroundLayer.contents = nsImage;
Add the delegate method:
- (void) animationDidStop:(CAAnimation *)anim finished:(BOOL)flag
{
NSImage * newImage = [(CABasicAnimation *)anim toValue];
self.backgroundLayer.contents = newImage;
}
Printing the nsImage pointer in the set-image method and newImage in the
animationDidStop: method shows that the two pointers are equal.
In this case, the animation runs from Image A to Image B, then jumps to Image
A, then jumps to Image B.
In all cases, self.backgroundLayer.actions is nil.
I'm thrashing at a task that ought to be simple and obvious. What am I missing?

Re: CA crossfade
I'm an adventurer, so I tried this:
===
self.backgroundLayer.contents = nsImage;
CABasicAnimation * crossfade;
crossfade = [CABasicAnimation animationWithKeyPath: @contents];
crossfade.duration = 2.0;
crossfade.removedOnCompletion = YES;
[self.backgroundLayer addAnimation: crossfade forKey: nil];
===
This works as I expect: The contents of the layer transition smoothly, without
flicker.

NSAttributedString location for drawing, glyph location and baseline
Hi, I have a subclass of NSAttachmentCell which draws itself into an NSTextView. Its y-location is wrong though when drawing the cell using - (void)drawWithFrame:(NSRect)cellFrame inView:(NSView *) controlView characterIndex:(NSUInteger)charIndex layoutManager: (NSLayoutManager *)layoutManager How do I determine the correct origin for cellFrame to ensure that the baseline of the text inside the NSTextView matches that of the text inside the cell to be drawn in the textview? In above call I use [self.displayWord drawInRect:cellFrame withAttributes:stringAttributes]; to draw the string which in turn uses boundingRectWithSize to figure out the NSRect dimensions to accommodate the string?
