title: Xcode - setFocus on a text field, becomeFirstResponder isn't enough
body: <p>At the moment, I trigger a method on '<code>Did End On Exit</code>' in my app (I'm aware that this may not be the greatest way of doing it but I'm very new to Objective C and Xcode for that matter and I'm simply doing what feels comfortable to me).</p>
  <p>This method resigns the <strong>firstResponder</strong> from the current text field and applies it to a later text field.</p>
  <p><em>The problem</em> I'm facing is that the keyboard covers the next text field so that the use has no idea where the focus is and therefore what they are required to type.</p>
  <p>How do I get it so that my keyboard shifts down and actually shows the text box that is currently active? Making something the firstResponder simply doesn't do what I want it to, unless there's part of the implementation I'm missing.</p>
  <p>Here's my simple method:</p>
  <pre><code>- (IBAction)firstNameNext:(id)sender {
  [firstNameTextField resignFirstResponder];
  [surnameTextField becomeFirstResponder];
  }
  </code></pre>
  <p>Any advice would be super.</p>
