How can I start showing a paging-enabled UIScrollView in the middle view?

Question

I have a simple problem but I can't figure it out. I have a UIScrollView with three nested UIWebViews. I need to be able to "recycle" these views to actually scroll through lots of content.

My main problem is that I can't figure out how to show a view that isn't the very first, meaning that you can immediately swipe back from. Right now I have three views paging, but it starts at the first one, and you can move right two.

What can I do to make it so that I am always in the middle? With the ability to always swipe right OR left?

Thanks!

In the viewDidLoad or viewWillAppear methods for your viewController, try adding the following bit of code:

[self.myMainScrollView setContentOffset:CGPointMake(0,self.view.frame.size.width) animated:NO];

That'll scroll your larger scrollview over, so that the middle UIWebView is visible.

If that doesn't help, dig around in the UIScrollView and UIScrollViewDelegate documentation - you should find some good stuff there.
