title: How to add padding-left on a UIButton created programmatically?
body: <p>I am having a trouble adding left padding on a <code>UIButton</code>. I have a <code>UIButton</code> with <code>UIControlContentHorizontalAlignmentLeft</code>. I want the text to be displayed on the left side but it is too left. when I give the border, it doesn't look good. I would like to give some padding on the text about 5px like in CSS. I googled for the solution but can't find one particularly for <code>UIButton</code>. 
  Thanks in advance for help.</p>
