title: Display Emoji in UITextField
body: <p>I am trying to add emoji in <code>UITextField</code> with existing text.But I get only unicode in the textfield in place of emoji like <code>\ue415</code>. I have try the below code to set emoji in the textfield. </p>
  
  <p>I have a view in which there are buttons with images of emojis. on the click of that emoji i am appending the respective unicode of that emoji to the text. but in that unicode is appended in string format and not the actual symbol.</p>
  
  <p>If I try to set direct unicode in the textfield then it show the emoji but if i try to get the value from array then it is not showing the emoji.</p>
  
  <pre><code>NSString *strCode = [[arrPlist objectAtIndex:[sender tag]]objectForKey:@"UTFCode"];
  strCode = [strCode stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
  
  NSString *mycode = @"\ue415";
  if ([mycode isEqualToString:strCode]) 
   {
       NSLog(@"both are same");
   }
  NSLog(@"%@",[NSString stringWithFormat:@"strCode:%@ and mycode:%@",strCode,mycode]);
  messageField.text = [messageField.text stringByAppendingFormat:@"%@ %@",strCode,mycode];
  </code></pre>
  
  <p>And the output is like : </p>
  
  <p><strong>strCode:\ue415 and mycode:</strong></p>
  
  <p>Can anyone help me with how can i get the strCode same as myCode ?</p>
