UINavigationController在Xcode 9上崩溃 [英] UINavigationController Crashes on Xcode 9
问题描述
每次我尝试在我的应用程序上使用navigationController推送视图时，我都会收到下面提供的控制台消息。但是，如果我只推动简单的视图控制器它工作正常，它只发生在导航控制器上。
Every time I try to push a view with navigationController on my application I get the console message provided below. But if I only push the simple view controller it works fine, it happens only with navigation controller.
我没有使用第三方库推送视图，我查了一下UIkit框架没关系，我也在构建之前清理项目，也尝试使用与我的自定义视图控制器不同的新视图控制器，但错误是相同的，它只发生在新版本的Xcode 9.0上，在早期版本8.0上这没有不会发生。
I'm not using a third party library to push views, I checked UIkit framework is OK, I also clean the project before building, also tried with a new view controller different from my custom view controller but the error is the same, it is only happening on new version of Xcode 9.0, on Previous version 8.0 this didn't happen.

此处是我在didFinishLaunchingWithOptions上的代码示例
here is an example of my code on didFinishLaunchingWithOptions
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
CustomViewController *startUpVC = [[CustomViewController alloc] init];
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:startUpVC];
使用导航控制器后，它会崩溃。
after use navigationcontroller sentence it crashes.
推荐答案
选择View Controller，然后转到Editor-> Embed In-> Navigation Controller。因为有时控制器不在导航控制器层次结构中，所以当用户想要推送到另一个控制器时应用程序崩溃。希望它会有所帮助。
Select your View Controller and then go to Editor->Embed In->Navigation Controller . Because some time if controller is not in Navigation controller hierarchy then app crash when user want to push to another controller. Hope it will help.
