Tried this with my NSCollectionViewItem's view. I first subclassed
NSCollectionViewItem and added this method:
- (void)awakeFromNib
{
[(AutoResizingView* )[self view] setup];
}
Basically just calls the "setup" method of the NSCollectionView's
view. Then this is my setup method in the subclass of NSView:
- (void)setup
{
[[tv textContainer] setLineFragmentPadding:0.0];
(void) [[tv layoutManager] glyphRangeForTextContainer:[tv
textContainer]];
[self setFrame:NSMakeRect([self frame].origin.x, [self
frame].origin.y, [self frame].size.width, [[tv layoutManager]
usedRectForTextContainer:[tv textContainer]].size.height)];
}
"tv" is the NSTextView. What I end up with is this:

Each of the little grey bubbles is an NSCollectionViewItem, and it
seems to be deformed.

Welcome to the wonderful world of the Cocoa text system! You need to
go deeper into the text system and look at the NSLayoutManager object:
- (NSRect)usedRectForTextContainer:(NSTextContainer *)aTextContainer
file:///Developer/Documentation/DocSets/com.apple.adc.documentation.AppleSnowLeopard.CoreReference.docset/Contents/Resources/Documents/documentation/Cocoa/Conceptual/TextLayout/TextLayout.html
This is listed as a common task in that document: "Calculating Text
Height"
