title: iOS Email Keyboard has Emoji button, can this be disabled?
body: <p>When setting the keyboard in IB or programatically as below for a UITextField.</p>
  
  <pre><code>[textFieldOutlet setKeyboardType:UIKeyboardTypeEmailAddress];
  </code></pre>
  
  <p>The keyboard has an Emoji icon which means you can type in Emoji's in an email address (which is a bit rubbish).  Can this be disabled?  I understand I can change the type to ASCIICapable but then I do not have the easy access to @ and . signs.</p>
  
  <p>I have worked around it with this which just stops the Emoji being entered but the button is still there (<a href="https://stackoverflow.com/questions/8664134/ios-5-how-can-i-disable-emoji-keyboard-in-my-application">Credit Here with MeganZhou answer</a>).</p>
  
  <pre><code>- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string
  {
      if ([textField isFirstResponder])
      {
          if ([[[textField textInputMode] primaryLanguage] isEqualToString:@"emoji"] || ![[textField textInputMode] primaryLanguage])
          {
              return NO;
          }
      }
  
      return YES;
  }
  </code></pre>
  
  <p>I have also noted that the icon is there when you are typing an email address in Mail too.</p>
  
  <p>This is iOS8 but may also be in earlier version.</p>
