导航控制器中的iOS ScrollView +页面控制器：如何更改每个页面的导航栏标题？

Question

In my app I have a UINavigationController. One of the views in the NavigationController has a ScrollView + Page Control combo. There are 3 pages in the scroll view. Is there any way to change the title of the NavigationBar according to the scroll view page on which you currently are?

I tried these two methods found in other posts:

self.navigationItem.titleView

and

viewController.title = @"title text";

but they didn't work. And on top of all I'm not even sure where in the code I should change the title. In the change page function ?

Any help is greatly appreciated.

I solved the problem by doing self.title = @"title". I put the code in the method which takes care of scrolling around the pages.
