Question

我一直在搜索堆栈溢出，我无法解决问题，我在AppDelegate.m中有以下代码：

UINavigationController *navigationController = (UINavigationController *)self.window.rootViewController;
        UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:storyboard bundle: nil];
        InternetConnectionViewController *controller = (InternetConnectionViewController*)[mainStoryboard instantiateViewControllerWithIdentifier: noInternet];
        [navigationController pushViewController:controller animated:YES];

但是给我一个错误......：

Uncaught exception: -[CustomSplitViewController pushViewController:animated:]: unrecognized selector sent to instance 0x17884860
2016-06-16 02:34:14.896 --[3340:1197655] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[CustomSplitViewController pushViewController:animated:]: unrecognized selector sent to instance 0x17884860'

libc++abi.dylib: terminating with uncaught exception of type NSException

编辑 - 更新 我设法实现它，现在正在工作......但是当我尝试这样做时：

UINavigationController *navigationController = self.navigationController;
 UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:@"Main" bundle: nil];
    HomeViewController *controller = (HomeViewController*)[mainStoryboard instantiateViewControllerWithIdentifier: viewC];
    [navigationController pushViewController:controller animated:YES];

在InternetViewController中，它给出了以下错误：

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UINavigationController setPanGestureEnabled:]: unrecognized selector sent to instance 0x16942a00'

Answer 1

在AppDelegate.h文件中创建属性

@property (strong, nonatomic) UINavigationController *navController;

然后

self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];

MainTabBarController *mainTabbarController = [storyboard instantiateViewControllerWithIdentifier:@"MainTabbar"];
self.navController = [[UINavigationController alloc] initWithRootViewController:mainTabbarController];
self.window.rootViewController = self.navController;
[self.window makeKeyAndVisible];

Answer 2

试试这个

UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:storyboard bundle: nil];
InternetConnectionViewController *controller = (InternetConnectionViewController*)[mainStoryboard instantiateViewControllerWithIdentifier: noInternet];
UINavigationController *navObj = [[UINavigationController alloc]initWithRootViewController:controller];
self.window.rootViewController = navObj;

希望这有帮助！
