title: iPhone UITextField background color
body: <p>I am unable to control the background color of a <code>UITextField</code> with a <code>borderStyle= UITextBorderStyleRoundedRect</code>.  With this border style the <code>backgroundColor</code> property only seems to control a very narrow line along the inner edge of the rounded rectangle.  The rest of the field remains white.</p>
  
  <p>However, if the <code>borderStyle</code> is set to <code>UIBorderStyle=UITextBorderStyleBezel</code> then the entire background of the <code>UITextField</code> is controlled by its <code>backgroundColor</code> property. </p>
  
  <p>Is this a feature?  Is there a way to control the <code>backgroundColor</code> of a <code>UITextField</code> with a <code>borderStyle=UITextBorderStyleRoundedRect</code>?</p>
