title: Finding out source of nsrangeexception
body: <p>I have an <code>NSRangeException</code> error that does not occur all the time(especially when I am debugging). It comes up randomly, and I am unable to figure out where it is coming from. I have lots of array manipulation, so its difficult to eliminate it that way. </p>
  
  <p>My question is whether I can get a clue , for example class and line number from the debugger output, for example what are the numbers 12109 and 707?:</p>
  
  <pre><code>2012-03-15 09:25:15.303 appname[12109:707] *** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayI objectAtIndex:]: index 2 beyond bounds [0 .. 0]'
  </code></pre>
  
  <p>Any pointers appreciated.</p>
