Ios 显示视图时导航栏不显示?
在另一个文件中,我从另一个故事板创建了一个视图控制器实例,并将其显示为:Ios 显示视图时导航栏不显示?,ios,swift,storyboard,Ios,Swift,Storyboard,在另一个文件中,我从另一个故事板创建了一个视图控制器实例,并将其显示为: let viewController:UIViewController = UIStoryboard(name: "UserProfile", bundle: nil).instantiateViewControllerWithIdentifier("profileID") as! ProfileViewController self.presentViewController(viewController, animat
let viewController:UIViewController = UIStoryboard(name: "UserProfile", bundle: nil).instantiateViewControllerWithIdentifier("profileID") as! ProfileViewController
self.presentViewController(viewController, animated: true, completion: nil)
在我的故事板中,我有正确的故事板ID,并将我的视图控制器嵌入到UINavigationController中。我还将初始视图控制器设置为UINavigationController
为什么它没有显示?创建视图控制器的对象,然后将导航控制器添加到其中,然后显示它:
let VC1 = self.storyboard!.instantiateViewControllerWithIdentifier("MyViewController") as! ViewController
let navController = UINavigationController(rootViewController: VC1) // Creating a navigation controller with VC1 at the root of the navigation stack.
self.presentViewController(navController, animated:true, completion: nil)
好的,您现在展示的是视图控制器(请注意,它不是导航控制器) 您可以做什么:
let viewController:UIViewController = UIStoryboard(name: "UserProfile", bundle: nil).instantiateViewControllerWithIdentifier("profileID") as! ProfileViewController
[self.navigationController pushViewController:viewController animated:YES];
let viewController:UIViewController = UIStoryboard(name: "UserProfile", bundle: nil).instantiateViewControllerWithIdentifier("profileID") as! ProfileViewController
let navigationController = UINavigationController(rootViewController: viewController)
self.presentViewController(viewController, animated: true, completion: nil)
对于仍然使用Objective-C的用户:
UIStoryboard *sb = [UIStoryboard storyboardWithName: @"Storyboard" bundle: [NSBundle mainBundle]];
ViewController *vc = [sb instantiateInitialViewController];
UINavigationController *nc = [[UINavigationController alloc] initWithRootViewController: vc];
[self presentViewController:nc animated:YES completion:nil];

您也可以使用objective-c执行相同的操作。
