I am new to collection views in Objective-C. Can anyone tell me why I can't see my UILabel embedded in the transparent UIView and the best way to resolve. I want to also segue from the cell to several various UIViewControllers based on the selected index cell.

I am using GitHub project https://github.com/mayuur/MJParallaxCollectionView

Overall, in MJRootViewController.m I wanted to add a UIView with a transparency and a UILabel with details of the cell from a array.
