title: UIButton with title under the imageview
body: <p>I want to creat an UIButton programmatically with the title under the imageView.</p>
  
  <p>Size of the button : 170 * 120
  Size of the imge : 50 * 50
  Size of the title : depend of the text.</p>
  
  <p>I know I'have to use but I don't know how :</p>
  
  <pre><code>[_button setTitleEdgeInsets:UIEdgeInsetsMake(0.f, 0.f, 0.f, 0.f)];
  [_button setImageEdgeInsets:UIEdgeInsetsMake(0.f, 0.f, 0.f, 0.f)];
  </code></pre>
  
  <p>I think I should calculate the size of the title and then Use the EdgeInsets.</p>
  
  <p>Thank you. </p>
