Without seeing any code we can't help you with this. But you can find the problem yourself, the error message even tells you what to do: set a breakpoint on malloc_error_break
and you usually will find the code that caused the problem in the stack trace.
Just because it works in the simulator just doesn't mean that your code is 100% correct. some bugs only show up on a real device (or vice versa).
