I push a ViewController which contains not too many views, UIScrollView which contains 10 views inside, I have a singleton ViewController and push it again and again without releasing and allocation again the ViewController, so all the things I do it in viewDidLoad(), and viewWillAppear(), but the animation is slow and choppy, what it could be?

You could start by using Instruments > Time Profiler and see if there is any part of your code that is taking longer than necessary.

You could also use the Instruments > Core Animation tool which can be used to flag parts of your screen that not drawing/animating efficiently.

If you're using an old iPhone or an original iPod - with complex screens, i've noticed some apps a bit choppy.
