Random EXC_BAD_ACCESS in a place that it cannot happen

Question

I\'m receiving EXC_BAD_ACCESS at random times in a place that I confirmed the exception should not happen.
The line its happening on is

`[[LevelEditorSce         


        

Answer 1

The line of code that your app crashes on might not be the cause of the problem. Most likely your method call is fine. Otherwise you'd receive a "message sent to unrecognised selector" error.

The best steps are to run the Analyzer. Failing that Profile using Leaks in Instruments.
