问题描述

我有基于视图的应用程序，我不想从第一个标准视图开始，我应该如何从另一个视图开始?！

I've got view-based application, I don't want to start with the first standart view, how should I start with another view?!

推荐答案

您可以更改 MainWindow.xib 文件，以将视图控制器添加为主窗口的子视图.或者，您可以通过以下代码在 applicationdidFinishLaunchingWithOptions:方法中执行此操作.

You can change the MainWindow.xib file to add your view controller as the subview of the main window. Or, you can do it by code like this, in applicationdidFinishLaunchingWithOptions: method.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    YourViewController *vc = [[YourViewController alloc] init];

     // You can add it as subView
    [self.window addSubview:vc]; 

    // Or, add it as rootViewController (available from iOS 4.0)
    self.window.rootViewController = vc;

    [vc release];
    [self.window makeKeyAndVisible];
    return YES;
}
