title: Get object type thats randomly chosen from Array?
body: <p>I have a NSArray that is filled with different types of objects. Lets say one is a NSDictionary and another is NSData.
  How would I randomly chose a object from this array and then check what kind of object it is.
  So if it a NSDictionary, I will do method A.
  Or if it is NSData, I will do method B.</p>
  
  <p>How would I put this into code?</p>
  
  <p>Thanks!</p>
