以编程方式更改 viewController
从我的navigationController我有两条路径：
navigationController --> ViewControllerA - ViewControllerB（当前显示）。
和导航控制器 --> ViewController1 --> ViewController2。
我想从 ViewControllerB 转到 ViewController2。
这是我尝试过的：
[self.navigationController popToRootViewControllerAnimated:YES]; // Works fine
AppDelegate app* = [[UIApplication sharedApplication] delegate];
LocationsViewController* locationsViewController = [[LocationsViewController alloc] initWithNibName:@"LocationsView" bundle:nil];
locationsViewController.title = @"Title";
[self.navigationController pushViewController:locationsViewController animated:YES];
self.navigationController PushViewController 不起作用。
我在应用程序委托中引用了 viewController1 并尝试了 [app.viewController1 PushViewControleranimated:YES]; ，但这也不起作用。
你如何解决这个问题？
From my navigationController I have two paths:
navigationController --> ViewControllerA -- ViewControllerB (currently showing).
and navigationController --> ViewController1 -->ViewController2.
I want to go from ViewControllerB to ViewController2.
Here's what I tried:
[self.navigationController popToRootViewControllerAnimated:YES]; // Works fine
AppDelegate app* = [[UIApplication sharedApplication] delegate];
LocationsViewController* locationsViewController = [[LocationsViewController alloc] initWithNibName:@"LocationsView" bundle:nil];
locationsViewController.title = @"Title";
[self.navigationController pushViewController:locationsViewController animated:YES];
The self.navigationController pushViewController doesn't work.
I have a reference to viewController1 in App delegate and tried [app.viewController1 pushViewControler animated:YES];, but that doesn't work either.
How do you solve this problem?

想通了。这有帮助。

显然，如果您将另一个视图控制器推到 poptorootviewcontroller 之上，则无法对其进行动画处理。
谢谢！
Figured it out. This helped.

Apparently, the poptorootviewcontroller can't be animated, if you're pushing another view controller on top of it.
Thanks!
