iPhone SDK：如何从登录界面切换到导航界面？ [英] iPhone SDK: how to switch from a login screen to a navigation interface?

问题描述

我开始从事iPhone开发，并且已经学过一些教程，但请指出我是否走错了方向。我已经实现了自己的UInViewController和一个登录屏幕视图（带有xib）。

I am beginning in iPhone development and have followed a few tutorials, but please indicate me if I'm going in the wrong direction. I have implemented my own UInViewController and a login screen view (with its xib).

我想要做的是点击登录按钮后，它会显示RootViewController.xib，其中包含Xcode的默认导航应用程序模板。

What I would like to do is that after clicking on the login button, it displays the RootViewController.xib, which includes the Xcode's default navigation application template.

这可能吗？怎么样？

非常感谢你的帮助。

推荐答案

发送一个登录时通知您的AppDelegate并从keyWindow中删除视图并将navigationController添加到同一个keyWindow。

Send a notification to your AppDelegate when you do the login and remove the view from the keyWindow an add the navigationController to the same keyWindow.

- (void) applicationDidFinishLaunching: (UIApplication*) application {
    [_window addSubview: [_loginViewController view]];
    [_window makeKeyAndVisible];
}

// This method is on AppDelegate   
- (void) loginComplete {
    [[_loginViewController view] removeFromSuperview];
    [_window addSubview: [_navigationController view]];
}
