UITabBarController - Adding/Removing items

Question

Hi,
Can anybody tell me how can I add or remove a ViewController item from a tabBarController at runtime? Or is there some way to update some item's specific ViewController at runtime?
I m using a webview which loads different url each time, I want to update its tabBar item acordingly, so that the user should be able to view the latest webpage.

You can do both. The tabbar has a list of controllers that you can assign. Unfortunately I haven't seen anyway to manipulate the list directly so you have to create a new array and reassign. Like this:
NSMutableArray* controllers = [[tabbar.viewControllers mutableCopy] autorelease];
[controllers insertObject:newVC atIndex:0];
[tabbar setViewControllers:controllers];
If you're doing a simple append you can shorten it a bit:
[tabbar setViewControllers:[tabbar.controllers arrayByAddingObject:newVC]];
If you want to 'update' a view controller at runtime, you simply grab the controller you want from the controllers array and modify it... can't help much further without knowing what you're having trouble with.
