You might find the answers to this question helpful: UICollectionView cell subviews do not resize

In most cases the works in iOS7 but not on iOS 8 auto layout problems seem to stem from the root view not being sized correctly in iOS 8, particularly when we set translatesAutoresizingMaskIntoConstraints to NO. For my views I was able to set the root view's frame in layoutSubviews (or whichever appropriate initializer that does have the correct bounds) and this resolved the issue.

self.contentView.frame = CGRectInset(self.bounds, 0, 0);

As shown in the answer above, you could also do

self.contentView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;

and then turn translatesAutoresizingMaskIntoConstraints back to NO before you start setting your own constraints in code.

Definitely hate that so much of our time is taken with these annoying gotchas.
