Question

I have a UITabBarController, which is the second item in a UINavigationBarController. Within the UITabBarController are a couple of views, one of which is a UIViewController subclass called AccountViewController. Got that?

Login View Controller -> UIViewController + UITabBarController - > Account View Tab -> Button

I want to use a button – Logout – to pop back to the Login view. How would I do that?

Answer 1

Assuming you are creating the UITabBarController within one of the UIViewControllers which are part of the string of view controllers within the UINavigationController where you have done something similar to this:

UITabBarController *mytabs = [[UITabBarController alloc] init];
[self.view addSubview:mytabs.view];
mytabs.delegate = self; // This is key to getting back your UINavigationController

You can call this from within one of the UIViewControllers that are added to your mytabs.viewControllers array like so:

[[(UIViewController *)self.tabBarController.delegate navigationController] popViewControllerAnimated:YES];

You can also specify if you want it to go to a specific viewController index in the UINavigationController stack ( just in case your Login viewController isn’t the next one down or the root view controller ).
