How to find a UICollectionViewCell's coordinates relative to the App Window

Question

Is it possible to translate a UICollectionViewCell\'s coordinates from being relative to the UICollectionView to being relative to the superview<

Answer 1

If I understand you correctly, I think the problem is that you first have to correct for the scroll view's contentOffset, which is easy to do since UICollectionView is a subclass of UIScrollView.

CGRect frame = CGRectMake(0.0,
                          0.0,
                          cell.frame.size.width,
                          cell.frame.size.height);
CGPoint correctedOffset = 
 CGPointMake(cell.frame.origin.x - collectionView.contentOffset.x,
             cell.frame.origin.y - collectionView.contentOffset.y);
frame.origin = [cell convertPoint:correctedOffset toView:self.view];

I tested this in one of my UICollectionView demo apps and it seems to work. Give it a try.
