问题描述
如何通过initWithRootViewController以外的方法设置UINavigationController的rootViewController?
How Do I set the rootViewController of UINavigationController by a method other than initWithRootViewController?
我想使用initWithNavigationBarClass:toolbarClass:为我的NavigationController交付自定义工具栏，所以我认为我不能使用initWithRootViewController.
I want use initWithNavigationBarClass:toolbarClass: to deliver a custom toolbar for my NavigationController, so I don't think I can use initWithRootViewController.
推荐答案
您可以通过调用setViewControllers来解决此问题.
You can solve this by calling setViewControllers.
赞:
UINavigationController *navigationController = [[UINavigationController alloc] initWithNavigationBarClass:[MyNavigationBar class] toolbarClass:[UIToolbar class]];
[navigationController setViewControllers:@[yourRootViewController] animated:NO];
快速版本:
let navigationController = UINavigationController(navigationBarClass: MyNavigationBar.self, toolbarClass: UIToolbar.self)
navigationController.setViewControllers([yourRootViewController], animated: false)
