如何在应用程序运行时释放标签栏视图？
我有一个应用程序，用户在主屏幕上登录，这是要显示的第一个屏幕。登录后，会出现一个选项卡栏视图。有一个选项卡允许用户注销，完成后，主屏幕会再次出现（以允许其他用户登录等）。我希望完成此操作后，将标签栏中加载的旧数据从内存中删除。目前，我正在设置 hidesBottomBarWhenPushed 来隐藏它，但数据不会被删除。我该怎么做呢？
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?

您是否尝试过像平常一样解除分配标签栏？例如，将
[TabBar release];放在登录视图中的- (void)dealloc {下，因为根本没有选项卡栏。或者您可以将 dealloc 放在-BackToMainMenu方法下。这是否会删除您想要发布的任何数据？希望这有帮助。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-BackToMainMenumethod. Is that getting rid of any data you want released? Hope this helps.
