Horizontal menu with UIScrollView

[joaphone]

Hello,

The other day I was surfing the app store and found an application [1] that shocked me, specially its horizontal menu with infinite loop. I liked so much the effect so I tried to do it for fun.

I was able to achieve the horizontal menu with infinite loop using a UIScrollView and adding some UIButtons to it, and simulating the infinite loop with scrollView.scrollRectToVisible method.

The last problem that I'm facing and I don't know how to solve is that when I call scrollRectToVisible to relocate the UIScrollView to simulate infinite loop, I lose acceleration effect and causes a visual loss.

Anyone knows how to know the acceleration in a specific moment to apply just after scrollView.scrollRectToVisible is called.

Anyone have other ideas?

Thanks in advance.
