Question

I have the following object structure:

• UITabBarController
  • UINavigationController
    • UITableViewController

It used to work, but then I added the UITabBarController into the mix and made a bunch of other large changes and somewhere in between it stopped.

So far I have:

• created a new project with that structure, and that seems to work OK.
• checked that there’s only one view with scrollsToTop
• tried adding a new UITableViewController directly under UITabBarController… still doesn’t work.

One thing that might be of use is that -scrollViewShouldScrollToTop: isn’t even being called, even though the table view controller’s tableView.delegate is set to the controller.

Answer 1

Just came across this problem myself.

If, like me, you started from the tab bar template Apple provides, then you have to add the following line to applicationDidFinishLaunching: in your app delegate:

[window makeKeyAndVisible];

This one line is what fixed it for me.
