title: Adding the "Clear" Button to an iPhone UITextField
body: <p>How do you add that little "X" button on the right side of a UITextField that clears the text?  I can't find an attribute for adding this sub-control in Interface Builder in the iPhone OS 2.2 SDK.</p>
  
  <p><strong>Note:</strong> In Xcode 4.x and later (iPhone 3.0 SDK and later), you can do this in Interface Builder.</p>
