Is there a way to change Views in iOS without using UINavigationController?
提问by Tony Lukasavage
I have a login page at the beginning of my app that I do not want on the view stack. Is there a way to load my first post-login view after the login without using UINavigatorController?
我的应用程序开头有一个登录页面，我不想在视图堆栈中显示该页面。有没有办法在登录后加载我的第一个登录后视图而不使用UINavigatorController？
Is there a better way to be doing this? Should I be using 2 UINavigationControllers? Is there a way to change the RootViewControllerfor a UINavigationController?
有没有更好的方法来做到这一点？我应该使用 2UINavigationControllers吗？有没有办法改变RootViewControllera UINavigationController？

Yes, you can change root controller of window. Set window's property rootViewControllerto new controller and you're done. Don't forget though that first controller (one you are removing) will not receive viewWillDisappear:and viewDidDisappear:messages. Send them yourself before switching controllers if you're interested in them.
是的，您可以更改窗口的根控制器。将窗口的属性设置rootViewController为新控制器，您就完成了。不要忘记尽管第一个控制器（您要删除的控制器）不会收到viewWillDisappear:和viewDidDisappear:消息。如果您对它们感兴趣，请在切换控制器之前自己发送它们。
