ios - 如何以编程方式打开 UINavigationController

Question

我正在尝试以编程方式打开 UINavigationController。这是我的代码:

UIViewController *vc = [[UIStoryboard storyboardWithName:@"Storyboard"
  bundle:nil] instantiateViewControllerWithIdentifier:@"ViewControllerID"];
UINavigationController *nc = [[UINavigationController alloc] 
   initWithRootViewController:vc];
nc.modalTransitionStyle = UIModalPresentationNone;
[self presentViewController:nc animated:YES completion:NULL];

我不断收到以下错误:

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Pushing a navigation controller is not supported'

你是完全正确的，但不是展示，只是插入你的导航 Controller 。

例如

UIViewController *vc = [[UIStoryboard storyboardWithName:@"Storyboard"
  bundle:nil] instantiateViewControllerWithIdentifier:@"ViewControllerID"];
UINavigationController *nc = [[UINavigationController alloc] 
initWithRootViewController:vc];
[self pushViewController:nc animated:YES];
