Question

The structure of my MainStoryboard is:

->Tab Bar Controller -> Navigation Controller -> View Controller (Search)

The behaviour I want to have is that when the user re-selects the Search tab, the UIScrollView on it scrolls to the top. I am unsure how to get the event from the TabBarController, however.

I’ve been looking at a lot of stuff about UITabBarDelegate, particularly:

- (void)tabBar:(UITabBar *)tabBar didSelectItem:(UITabBarItem *)item

I have, not quite managed to get this to work properly though. I am very unsure about how to go about setting the delegate (assuming that is the way it’s done). I’ve tried hooking it up in IB, but it wouldn’t let me. I also tried to get the UITabBar from the AppDelegate (after looking at some seemingly-related answers).

Any pointers will be greatly appreciated (unless they’re null).

Answer 1

UITabBar *aTabBar = [UITabBarItem alloc] init];

….Any other modifications you want to make to aTabBar….

[aTabBar setDelegate:self]
