Nothing happens if press on transparent part of uicollectionviewcell in iOS8 Today Extension

Question

I have widget with collection of icons and these icons are on transparent background. UICollectionViewCell is also transparent. The problem is that if press on transparent part of the cell -

(void)collectionView:didSelectItemAtIndexPath:

is not called. But if change cell's backgroundView to black color with alpha = 0.01 everything works well. I have a feeling that alpha solution is not the best one. Am I doing something wrong or anybody have better solution?

Collection views with alpha = 0.01

You NEED the 0.01 alpha workaround.

According to Apple's DTS, it is an iOS 8 bug.

The solution for the moment is to create a empty text label as a background view, or add it in the .xib file as a first view.
