  <p>I am able to append string as:</p>
  
  <pre><code>NSString *aString =[name stringByAppendingFormat:@"Hello"];
  </code></pre>
  
  <p>but its not being possible to use an object of NSString for appending for example in my case</p>
  
  <pre><code>NSString *aString =self.stringName;
  NSString *resultString =[name stringByAppendingFormat:[NSString stringWithFormat:@"%@",aString]];
  </code></pre>
