iphone - 从 UITabBarController 弹出 UIViewController

Question

我想从我的应用程序中的功能中弹出我ViewController的功能，我为此添加了代码，但仅在我的第一个 .not 中弹出。TabBarViewControllerLogouttabbarViewController

Answer 1

假设您具有以下结构

窗口 - UINavigationController - (LoginViewController) - UITabBarController - (VC,VC)

这会起作用

AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication]delegate];
UINavigationController *navController = (UINavigationController *)appDelegate.window.rootViewController;
[navController popToRootViewControllerAnimated:YES];

Answer 2

在您的注销按钮操作方法中尝试此代码

AppDelegate *appdelegate = (AppDelegate*)[[UIApplication sharedApplication]delegate];
LoginVC *viewController = [[LoginVC alloc]initWithNibName:@"LoginVC" bundle:nil];
NSArray *array = @[viewController];
[appdelegate.navController setViewControllers:array];
[appdelegate.tabbarController.view removeFromSuperview];
[[appdelegate tabbarController] removeFromParentViewController];
NSLog(@"array - > %@",array);
[appdelegate.window setRootViewController:appdelegate.navController];

您可以[self.navigationController popToRootViewControllerAnimated:YES];用于将 viewController 弹出到根 viewController
