iOS 8 GM does not update constraints on collection views

Question

In Xcode 6 Beta 7 and all versions before it, I had a collection view that would update its constraints on its cells when an iPad would rotate between landscape and portrait. No

Answer 1

You need to make a subclass of UICollectionViewCell and make that subclass as the superclass of ALL of your cells.

Example:

@interface MDTCollectionViewCell : UICollectionViewCell
@end

@implementation MDTCollectionViewCell

- (void)setBounds:(CGRect)bounds {
    [super setBounds:bounds];
    self.contentView.frame = bounds;
}

@end
