title: Memory Leak from UIImageView
body: <p>I currently working on a personal project in iOS7, and I must display several images on a Galarie scroll view. To do this I created a <code>UIImage</code> then I insert it in a <code>UIImageView</code>. I stock all my <code>UIImageView</code> in a <code>NSMutableArray</code>.
  I show all the pictures on the <code>UIScrollView</code>.</p>
  
  <p>With the test I could perform, the memory used can go over 500 MB.</p>
  
  <p>How can I optimize memory? How the camera base application it happens to you to display  over 1000 photos?</p>
  
  <p>Thank you in advance. Cordially.</p>
