Question

For the navigation in my app I’m using a UITabBarController. This works fine, but in one of my viewcontrollers I want to push another view controller into the tabbar view.
In other words I want to replace the selected viewcontroller with another one.
I’m doing this with the following code:

self.tabBarController.selectedViewController = self.otherViewController;

The list of viewControllers in my TabBarController does not contain the otherViewController.
This trick works fine in IOS 4.3, but IOS 5 does not like it.

Does anyone know a solution which is accepted by IOS 5?

Answer 1

You want to REPLACE that view controller in the tabbar with another view Controller?
If so, you have to edit the viewControllers property in the tabbar by setting a new one. It would be something like:

UIViewController *thisIsTheViewControllerIWantToSetNow;
int indexForViewControllerYouWantToReplace;

NSMutableArray *tabbarViewControllers = [self.tabbar.viewControllers mutableCopy];

[tabbarViewControllers replaceObjectAtIndex:indexForViewControllerYouWantToReplace withObject:thisIsTheViewControllerIWantToSetNow];

self.tabbar.viewControllers = tabbarViewControllers;

[tabbarViewControllers release];
