In Mobile Safari, you can open up multiple different windows, and navigate between them in sort of a zoomed out view. I have also seen this functionality in a few other apps as well.
Is there an API for doing this? I have an app that I'd like to integrate this functionality into, and I was hoping I could get a clue where to start by coming here.
The instance of your app is one, i think mobile safari use multiple views (UIWebView), not multiple windows; you have to play with UIPageControl and UIScrollView to recreate the safari effect in case you want display a webpage; use UIViews instead if you want display some button/image/etc.
