I have an application in which the user logs in at the home screen which is the first screen to be shown. After login, a tab-bar view comes up. There is a tab which allows the user to log-off and when this is done, the home screen comes up again (to allow another user to login,etc). I want the old data loaded in the tab-bar to be removed from memory when this is done. Currently, I'm setting hidesBottomBarWhenPushed to hide it but the data is not being deleted. How should I do it?
Have you tried dealloc'ing the tab bar like normal? For example put [TabBar release]; under your - (void)dealloc { in the login view since there is no tab bar at all. Or you can put the dealloc under a -BackToMainMenu method. Is that getting rid of any data you want released? Hope this helps.
