How catch a button's touch event by setting a breakpoint?

Question

I got an old project and tried to find out where is code responding the button's touch event.

I wandering if there is anyway to catch my touch on a button and break at the selector method or somewhere related like when you make a symbolic breakpoint.

Answer 1

you can override the event sending in UIApplication: - (void)sendEvent:(UIEvent *)event

see:

• https://developer.apple.com/documentation/uikit/uiwindow/1621614-sendevent?language=swift
• Subclass UIApplication with Swift (on SO)

by overriding that method you can get any event sent to your app and you can intercept any touch event
