Resize view of NSCollectionViewItem

Question

How do I programatically set the size of a view of an NSCollectionViewItem?

I tried doing this in an NSCollectionView subclass:

@implementation CustomCollectionView

- (NSCollectionViewItem *)newItemForRepresentedObject:(id)object {

    NSCollectionViewItem *newitem = [[self itemPrototype] copy];
    [newitem setRepresentedObject:object];  
    NSView *itemview = [newitem view];
    [itemView setFrame:NSMakeRect([itemView frame].origin.x, [itemView frame].origin.y,         [itemView frame].size.width, 500)];
    return newitem;
}

@end

However this code has no effect. I tried subclassing my NSView that I use for the NSCollectionViewItem, and adding setFrame: to the initWithCoder method, but I get an EXC BAD ACCESS crash when I do that.

You might checkout this open source NSCollectionView alternative from Steven Degutis which, coincidentally I think was just posted to GitHub today (I noticed it today via Twitter):

Looks like it allows you to have items with different heights.
