title: Setting up multiple UIImageView instances
body: <p>I would like to create a 4 x 6 grid of UIImageViews that each contain a slightly different image. I would also like to be able to randomly select one of the instances and change it's image.</p>
  
  <p>My question is what's the best way to set up the UIImageViews in a grid formation, perform a few actions between each setup, and randomly pick 1 of the 24 instances once setup is complete. Optimally, I wouldn't have to set up each one by one.</p>
  
  <p>Thanks in advance.</p>
