How can I get the first element in an NSDictionary?

Question

I have an array of NSDictionaries. How can I pull out the first element in the dictionary?

   NSArray *messages = [[results objectForKey:@"messages"] valueForKey:@"message"];              for (NSDictionary *message in messages)     {         STObject *mySTObject = [[STObject alloc] init];         mySTObject.stID = [message valueForKey:@"id"];               stID = mySTObject.stID;     }

There is no "first" element in an NSDictionary; its members have no guaranteed order. If you just want one object from a dictionary, but don't care which key it's associated with, you can do:

id val = nil; NSArray *values = [yourDict allValues];  if ([values count] != 0)     val = [values objectAtIndex:0];
