ios - 我添加了选项卡，但无法访问选项卡外的 View (ios)

Question

我的原始应用有 5 个主屏幕 View ，主屏幕中的按钮会打开不同的其他 View 。

我没有使用 Storyboard。最初应用程序中没有标签。然后我添加了标签以使用

显示主屏幕

    UIViewController *viewController1 = [[FirstViewController alloc] initWithNibName:@"FirstViewController" bundle:nil] ;
    UIViewController *viewController2 = [[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:nil];
    UIViewController *viewController3 = [[ThirdViewController alloc] initWithNibName:@"ThirdViewController" bundle:nil];
    UIViewController *viewController4 = [[FourthViewController alloc] initWithNibName:@"FourthViewController" bundle:nil];
    UIViewController *viewController5 = [[FifthViewController alloc] initWithNibName:@"FifthViewController" bundle:nil];

    UINavigationController *navigationController1=[[UINavigationController alloc]initWithRootViewController:viewController1];
    [navigationController1.navigationBar setBackgroundImage:[UIImage imageNamed:@"upwhitebg.png"] forBarMetrics:UIBarMetricsDefault];

    UINavigationController *navigationController2=[[UINavigationController alloc]initWithRootViewController:viewController2];
    [navigationController2.navigationBar setBackgroundImage:[UIImage imageNamed:@"upwhitebg.png"] forBarMetrics:UIBarMetricsDefault];

    UINavigationController *navigationController3=[[UINavigationController alloc]initWithRootViewController:viewController3];
    [navigationController3.navigationBar setBackgroundImage:[UIImage imageNamed:@"upwhitebg.png"] forBarMetrics:UIBarMetricsDefault];

    UINavigationController *navigationController4=[[UINavigationController alloc]initWithRootViewController:viewController4];
    [navigationController4.navigationBar setBackgroundImage:[UIImage imageNamed:@"upwhitebg.png"] forBarMetrics:UIBarMetricsDefault];

    UINavigationController *navigationController5=[[UINavigationController alloc]initWithRootViewController:viewController5];
    [navigationController5.navigationBar setBackgroundImage:[UIImage imageNamed:@"upwhitebg.png"] forBarMetrics:UIBarMetricsDefault];


     UITabBarController *tabBarController= [[UITabBarController alloc] init];
    tabBarController.viewControllers = @[navigationController1, navigationController2,navigationController3,navigationController4,navigationController5];
        //self.window.rootViewController = self.tabBarController;

    UIWindow *window = [[UIApplication sharedApplication] delegate].window;
    [window addSubview:tabBarController.view]

;

但是现在，当我单击主屏幕上的按钮时，如何显示选项卡外的 View ？以及如何从该 View 返回到第 5 个主屏幕选项卡 View 。

早些时候我使用这段代码来显示按下按钮时的 View

 listController = [[MenuListController alloc] initWithNibName:@"MenuListController" bundle:nil];
    SUP101AppDelegate *delegate6 = [[UIApplication sharedApplication] delegate];
    [delegate6.navController pushViewController:listController animated:YES]

Answer 1

您现在可以通过简单地将它们呈现在 tabController 上来启动其他 viewController。

listController = [[MenuListController alloc] initWithNibName:@"MenuListController" bundle:nil];
SUP101AppDelegate *delegate6 = [[UIApplication sharedApplication] delegate];
[self.tabBarController presentViewController:listController animated:YES completion:nil];

你还应该将 tabController 设置为 window RootViewController

self.window.rootViewController = tabBarController;
//[window addSubview:tabBarController.view]
