iOS objc_msgSend crash, with no report or warning given

Question

I am testing my app out, pushing it pretty hard, and I\'m getting it to crash (black screen, image doesn\'t save, drops back to springboard). However, I get no crash reports lo

Answer 1

sometimes that happens when you set an object as an observer for notifications, like

[[NSNotificationCenter defaultCenter] addObserver //details

and don't remove it from the observers list when it's released.
the system tries to send a message to it, and the app crashes because it's not there.

try adding

[[NSNotificationCenter defaultCenter] removeObserver:self];

in the dealloc function.
(even if you're working with arc, create a dealloc function, and write that in it).

good luck
