Question

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?

Answer 1

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