title: iOS - Animation effects - Image pop-in
body: <p>I'd like to have an image in my iphone app "pop-in" on screen rather than just appearing. By "pop-in" I mean that it would grow from a small dot to its actual size. For reference, this is exactly the same as the "pop" animation effect in Keynote.
  I'm completely new to iOS animations, so if someone could point me in the direction on the animation effects I would need to use, it would be greatly appreciated.</p>
  
  <p>Thanks</p>

  <p><strong>UPDATE</strong>
  I've added this code from the suggestions below. This works but it scales my image down, rather than up. I know that is because I have 0.01 as the transform scale size, but I would like to know how I can start out with an image of size 0.0 and scale up to 1. Is it just a matter to setting the size of my image to 0?
  Thanks</p>
  
  <pre><code>[UIView beginAnimations:nil context:NULL];
  [UIView setAnimationDuration: 0.2];
  image.transform = CGAffineTransformMakeScale(0.01, 0.01);
  [UIView setAnimationDelegate:self];
  [UIView commitAnimations];
  </code></pre>
