Having problems allowing interaction in UIView animation

Question

I have the following block of code to fade out an introView(UIView)

// Hide intro view after 5 seconds
[UIView animateWithDuration: 1.0
          delay: 5.0
         


        

Answer 1

I found another circumstance which could cause this. I haven't seen this answer anywhere else. It does not deal with alpha at all.

If you use a delay in the call to UIView.animate(), then even if you specify the .allowUserInteraction option, the view does NOT receive touches during the delay period. I have no idea why, but I could help it by moving the code block to another function, and using a performSelector after the same delay seconds, and in the block I run the code without delay.
