title: Change UITextField size programmatically
body: <p>I have a UITextField in my storyboard, which I bind to the ViewController.h with</p>
  
  <pre><code>@property (weak, nonatomic) IBOutlet UITextField *username;
  </code></pre>
  
  <p>In the ViewController.m I want to change the size and position of this UITextField username</p>
  
  <pre><code>[_username setFrame:CGRectMake(10.0, 10.0, 300.0, 200.0)];
  </code></pre>
  
  <p>I get no error, but nothing is happening to the UITextField username. It's still the same like in the IB.</p>
  
  <p>What's wrong?</p>
  
  <p>Thank you</p>
