Ok than try using enabling zombie environment.

Follow these steps:

  1. Click on project name and edit scheme.

enter image description here

  1. A pop over will appear, In that select Arguments tab. See bottom section Environment Variables. You can see + button at bottom part. Click on that button and add varialbe NSZombieEnabled with value YES.

enter image description here

  1. Now from same popover select Diagnostics tab. And mark Enable Zombie Objects.

enter image description here

Click close and again run your project, hope this will track down zombie objects at runtime which cause runtime crash.

  • Thanks for your answer.i tried with enabling zombies.if i give like myarr=[[NSMutableArray alloc]initWithObjects:@"hi", nil]; NSLog(@"myarry object at index 20 %@",[myarr objectAtIndex:20]); it is showing 2014-12-19 12:55:50.077 ExceptionBreakPoint[2840:42450] *** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayM objectAtIndex:]: index 20 beyond bounds [0 .. 0]' But i want which array is rised that exception , i have hundreds of such like arrays. – murali mohan Dec 19 '14 at 07:27
  • What about a simple error detect? Just remove the exception by checking the arrays size before trying to get its content. If the size is smaller then the index you try to access, you can make a log or a breakpoint or whatever you want to debug. – Thallius Dec 19 '14 at 07:32
