dequeuing UICollectionViewCell while debugging crashes app

Question

I'm trying to debug my app, but when I run it through Xcode, I get a crash saying -[UICollectionView _dequeueReusableViewOfKind:withIdentifier:forIndexPath:viewCategory:] This happens in cellForItemAtIndexPath : for the collection view, but it only happens when I'm debugging, if I install the app and run it without Xcode it works fine.

this is my code:

- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath {
    FFSIncidentCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:reuseIdentifier forIndexPath:indexPath]; 
    // Configure the cell 
    ...
}

Answer 1

So I figured this out, and hopefully this will help someone else. In my case, I have a UICollectionViewCell in a .Xib file. That cell has a UIScrollView and that UIScrollView has a UIView in it. The UIView is taller than the screen, so in IB I pulled it out of the scroll view so I could see it all, but I never moved it back to being a subview of the scroll view. Long story short, if you build a custom UITableViewCell or UICollectionViewCell, everything has to be a subview of the Cell, otherwise, CRASH!
