I am using Xcode 6.0 beta 4, I find that the buttons in UICollectionViewCellare not a response to the answer.
Details like:
UICollectionViewController
--- UICollectionViewCell
------ UIButton( UIButtonhas two restrictions autolayoutfor placement UIButtonin the vertical center and horizontal center in Cell)
Now let's make the size Cellapproximately as follows: (300, 1000)
Run the application on the iPhone Simulator or device with iOS 7.0 or 7.1.x, the button is insensitive, but check in the simulator iOS 8.0 this is normal. Also, if I change the cell sizeto (300, 200), the button works.
I think this is a bug in this version of Xcode, right?
And where can I run the Apple error?
