Segue无法从标签栏控制器中的ViewController运行

Question

I created a tabbar application . the root view is tabbar with navigation controller. When i tried to trigger segue from intial view controller of tabbar, its not working and throwing error in console

" Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Receiver () has no segue with identifier 'series'"

    Tabbar Code in appdelegate:

        self.tabBarController = [[UITabBarController alloc] init];
        self.tabBarController.tabBar.barTintColor = [UIColor blackColor];
        self.tabBarController.tabBar.tintColor = [UIColor redColor];

        HomeViewController *VC1 = [[HomeViewController alloc] init];
        VC1.title = @"Home";
        UINavigationController *VC1Navigation = [[UINavigationController alloc]
                                                 initWithRootViewController:VC1];
        wishListViewController *VC2 = [[wishListViewController alloc] init];
        VC2.title = @"My list";
        UINavigationController *VC2Navigation = [[UINavigationController alloc]
                                                 initWithRootViewController:VC2];
        SearchBarVC *vc3 = [[SearchBarVC alloc] init];
        vc3.title = @"Search";
        UINavigationController *VC3Navigation = [[UINavigationController alloc]
                                                 initWithRootViewController:vc3];

        ProfileViewController *vc4 = [[ProfileViewController alloc] init];
        vc4.title = @"More";
        UINavigationController *VC4Navigation = [[UINavigationController alloc]
                                                 initWithRootViewController:vc4];

        NSArray* controllers = [NSArray arrayWithObjects:VC1Navigation, VC2Navigation,VC3Navigation, VC4Navigation, nil];
        self.tabBarController.viewControllers = controllers;

        [[self.tabBarController.tabBar.items objectAtIndex:0] setImage:[UIImage imageNamed:@"homes.png"]];
        [[self.tabBarController.tabBar.items objectAtIndex:1] setImage:[UIImage imageNamed:@"wishlist.png"]];
        [[self.tabBarController.tabBar.items objectAtIndex:2] setImage:[UIImage imageNamed:@"searchs.png"]];
        [[self.tabBarController.tabBar.items objectAtIndex:3] setImage:[UIImage imageNamed:@"dots.png"]];

        self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
        self.window.backgroundColor = [UIColor whiteColor];
        self.window.rootViewController = self.tabBarController;
        [self.window makeKeyAndVisible];


Segue

[self performSegueWithIdentifier:@"Nav2SingleVid" sender:self];

Answer 1

Please check whether the segue is triggered:

1, Through a user gesture If a segue emanates from a gesture recognizer or from a tappable view, it becomes an action segue, meaning that it will be triggered automatically when the tap or other gesture occurs. Your source view controller class can prevent an action segue from being triggered. To do so, override this method:shouldPerformSegue(withIdentifier:sender:) 2, in code performSegue(withIdentifier:sender:)

The default implementation of this method does nothing; you can override it to pass relevant data to the new view controller or window controller, based on the context of the segue. The segue object describes the transition and includes references to both controllers involved in the segue.

Segues can be triggered from multiple sources, so use the information in the segue and sender parameters to disambiguate between different logical paths in your app. For example, if the segue originated from a table view, the sender parameter would identify the cell that the user clicked. You could use that information to set the data on the destination view controller.
