title: Wait, before iterating next loop in objective c (ios)
body: <p>I want to loop through an array of images, subsequently setting them as the new image of a uiimageview, but because it's a for loop it obviously does it so fast you cannot see a difference.</p>
  
  <p>I would like to add a pause of about 0.2s to the loop before it goes on to the next iteration.</p>
  
  <p>Is there a way to do this?</p>
  
  <p>And more importantly is there an easier way to accomplish what I want to do with some kind of inbuilt framework? thanks!</p>
