title: iPhone performance optimization best practices
body: <p>I was looking for a book, text, post or something talking about iPhone optimization but I couldn't find anything except for Apple documentation.</p>
  
  <p>I think it would be great to talk about which are the common steps you do when optimizing your apps performance. I'm now trying to improve my app memory usage and I've figured out it is really difficult when your app is complex.</p>
  
  <p>How do you handle view creation and destruction? Are you doing it by yourself or do you delegate on iPhone navigation controller?</p>
  
  <p>Do you use any trick to free some memory in your app?</p>
