title: Populating UITableView with Dictionary Data
body: <p>My Situation:</p>
  
  <p>I have an NSDictionary object. Keyed by NSNumber. Values are custom objects.</p>
  
  <p>I want to put dictionary values into a UITableView.  As far as I can tell, UITableView requires that its source collection be indexed so when cellForRowAtIndexPath is called, you can use the indexPath to look up the value.</p>
  
  <p>Problem is that when didSelectRowAtIndexPath is called, I want to look up the object from the dictionary, but I don't have the key. All I have is the indexPath.row.</p>
  
  <p>My solution:
  I create an array of keys. I use the index of the array to get the key, and then use the key to get the object out of the dictionary.</p>
  
  <p>My problem:
  This seems kind of sloppy especially since this is a routine task (populating the UITableView and then responding when someone touches a cell).  Is this the way it's designed to work or is there a better way?</p>
