title: iOS: How to cover entire button with image
body: <p>I am currently working on a iOS application where I am constantly changing the pictures of two buttons. The problem is that the picture of the button that constantly changes does not stretch over the entire button. I was wondering  what is the best way of doing this.
  I believe I am setting my image of my button normally and I cant figure out what to do. Any suggestions will be greatly appreciated.</p>
  
  <pre><code>leftButton setBackgroundImage:[UIImage imageNamed:[NSString stringWithFormat:@"%@",      [orangeImageArray objectAtIndex:randomPicture2]]] forState:UIControlStateNormal];
  </code></pre>
