无法找到导航控制器来导航另一个视图控制器

Question

我有一个自定义UIPageViewController，其中包含5个UIViewControllers，现在我想从其中一个UIViewController导航，但我无法理解，因为在UIViewControllers UINavigationController 1}}没有UIViewControllers。任何人都可以建议我，我如何从那些5 UIViewController导航到其他for A4i = A4{ii}？

您的代码 - [AppDelegate application:didFinishLaunchingWithOptions:] 可能看起来像这样（当然在检查你的跳过条件后）：

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
UIViewController *vc1 = [storyboard instantiateViewControllerWithIdentifier:@"MyAuth"]; //if you assigned this ID is storyboard
UIViewController *vc2 = [storyboard instantiateViewControllerWithIdentifier:@"Login"];  //if you assigned this ID is storyboard
UIViewController *vc3 = [storyboard instantiateViewControllerWithIdentifier:@"Details"];
NSArray *controllers = @[vc1, vc2, vc3];
UINavigationController *navController = (UINavigationController *)self.window.rootViewController;
[navController setViewControllers:controllers];

如果您将此粘贴到 - [AppDelegate application:didFinishLaunchingWithOptions:]，您会看到它立即生效。
