title: Sorting NSMutableArray?
body: <p>I want to be sort NSMutableArray and its structure is something like that,</p>
  
  <p>Object1:NSMutableDictionary</p>
  
  <pre><code>   Affiliation = 2165;
     CallLetters = abc;
     Channel = "2.1";
  
     ChannelLocation = "";
     ChannelSchedules =         (
     );
     DisplayName = abc;
     DvbTriplets =         (
     );
     FullName = "bc";
     IconAvailable = 1;
     Order = 1;
     ParentNetworkId = 2;
     ServiceType = Digital;
     SourceAttributeTypes =        
         HD
  
     SourceId = 11222;
     SourceType = Broadcast;
     TiVoSupported = 1;
     Type = "24-Hours";
  </code></pre>
  
  <p>Object2:NSMutableDictionary</p>
  
  <pre><code>   Affiliation = 1209;
     CallLetters = "xyz";
     Chann?el = "4.1";
  
     ChannelLocation = "";
     ChannelSchedules =         (
     );
     DisplayName = "xyz";
     DvbTriplets =         (
     );
     FullName = "xyz";
     IconAvailable = 1;
     Order = 2;
     ParentNetworkId = 5;
     ServiceType = Digital;
     SourceAttributeTypes = HD
  
     SourceId = 111
     SourceType = Broadcast;
     TiVoSupported = 1;
     Type = "24-Hours";
     VirtualChannelNumber = "4.1";
  </code></pre>

  <p>The array contains many objects, and those objects contain many dictionaries. I want to be able to arrange the above array in ascending order using the NSMutableDictionary key "Channel" ?</p>
  
  <p>How can I sort the array?</p>
