IBAction UIButton firing is delayed

I have a UIButton connected to an IBAction in Interface Builder.

The Problem:

  • The action firing and the de-highlight of the button both take a little bit to happen.

The Facts:

  • View structure:
    • View
      • 10 Buttons (connected via UIControlEventTouchUpInside to the IBAction
      • View (Subview)
        • Gesture recognizer
        • Text Field
  • The Subview has a UITapGestureRecognizer, which delaysTouchesBegan and delaysTouchesEnded both are set to NO
  • The action is happening in the main thread.
  • Testing a simple button (with no images or title, and only a simple NSLog), the result is the same

The Question: Why are firing and the de-highlight delayed?

Solution

  • In the end, I added somewhere some UIGestureRecognizer, and forgot to set delaysTouchesBegan to NO =(
