Delay of button's highlighted state

Question

I have the issue in two completely different situations, which makes it really weird.

1. Situation: A UIButton in as a subView of another UIView.
2. Situation:

Answer 1

I know it's been a long time, but I just faced a similar issue:

• My UIButton is a subview of UINavigationController.view
• There's no delay on the simulator
• But there's a delay to show the highlight on the device

I just found out that it only happens if I run the app from Xcode. If I disconnect the device and open the app from it's icon everything works just fine.

I hope it helps.
