iphone login view, how to reload controller

Question

Hello,

I am working on an application with a LoginViewController and a TabBarViewcontroller.

When the application is ran, I add the LoginViewController as a subView of window in the delegate. Once the login is ok, I remove the LoginViewController (removeFromSuperView) and add the TabBarViewController instead as a subview of windows.

This works fine.

In one of the tab of the TabBar I have a view containing a button to disconnect the user. When clicking on the button it performs the opposite than what described above: - remove the TabBarViewcontroller from the superView - add the loginViewController instead.

This works also fine except for 2 things:

• when I login again, I get directly on the last tab I used (the one with the disconnect button) when I'd like to get to the first one

• If I login with another user, the TabBarController is not refreshed (I see the data of the previous user... kind of dangerous:) ).

Well, those 2 things seems to be related to the same problem, the TabBarViewController is not unloaded and reloaded. Could you please help on how to do this ?

Thanks a lot, Luc

Answer 1

Maybe you should release your tabBarController when disconnecting and allocate it when connecting.

Answer 2

I post an NSNotification to solve this problem, your view controller can observe this and reload the tabController as needed.
