Question

I have a crash, and I can’t see why it’s occurring. I’d like to get more info on it.

The method that this is crashing in is:

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event

when I execute this line of code during debug step through:

[self.nextResponder manageTouches:touches];

this is displayed in the file history list:

asm__TERMINATING_DUE_TO_UNCAUGHT_EXCEPTION__ 0x01c1c000:1

The manageTouches method is in the parent object (a view controller).

Any tips for how to resolve are appreciated // 🙂

Answer 1

There could be a difference between the parent object (your view controller) and the nextResponder you are sending the message to. In the debugger you can make sure the pointers are the same. I would imagine there is some discrepancy here between the responder chain and the view hierarchy ownership chain.
