title: UIButton Highlighting Overcome default behaviour
body: <p>In a program much like the who want to be a millionaire... I have 4 option buttons.  It should flash red or green on press.  The four buttons have either red or green images as background images.  In the code setup I have such a method ready to setup the first question and when the second question gets set, the background images change accordingly.<br>
  Currently the default blue highlight is always appearing on the first pressing of any one the buttons and after that there are other issues.</p>
  
  <p>I could paste some different approaches here, (but they dont work).  So any suggestions would be good.</p>
  
  <p>Also in the IB, when you set the highlight with background image, that works.  I would use use, but for the same button, the back ground image must be changed programmatically.</p>
  
  <p>Thanks in advance for the help/suggestions!</p>
