title: NSDictionary - List all
body: <p>In a NSMutableDictionary like this: </p>
  
  <pre><code>[NSMutableDictionary dictionaryWithObjectsAndKeys:
  [NSString stringWithString:firstName], @"NAME",
  [NSNumber numberWithFloat:familyName], @"SURNAME",
  nil];
  </code></pre>
  
  <p>How can all of its elements be converted to the NSString? with the requirement that names and surnames are arranged in string like this: "name, surname, name, surname..."? </p>
  
  <p>This gives a string with all the names but not surnames: </p>
  
  <pre><code>NSString * result = [[urlArray valueForKey:@"NAME"] componentsJoinedByString:@", "];
  </code></pre>
  
  <p>Is there a way similar to the one above to create a string with all the values of NSMutableDictionary? </p>
