title: Reaching to deepest child level in NSDictionary
body: <p>I have a NSDictionary object with deep structures in it like arrays containing further array which contain dictionaries...</p>
  
  <p>I want to fetch an object down in the hierarchy. Is there any direct indexing way to fetch them using key names or something else?</p>
  
  <p>Its a pain to keep on calling objectForKey methos multiple time to reach to deepest child level.</p>
