从 UINavigationController 切换到 UISplitviewController

Question

我有一个 UINavigationController，它提供了几个 UIViewController。然后我想切换到 UISplitviewController 。

因此，我在我的应用程序委托中实现了一个方法 useSplitViewController，我从最后一个 UIViewController 调用该方法。它显示了 SplitView，但我无法旋转我的设备。我的 SplitviewController 内的 ViewController 没有获得旋转事件。我的错误是什么？我该如何解决？

 -(void)useSplitViewController{

    [self.menuViewController.view removeFromSuperview];
    self.menuViewController = nil;
    self.navcon = nil;

    self.splitViewController =[[UISplitViewController alloc]init];
    self.rootViewController=[[RootViewController alloc]init];
    self.detailViewController=[[[FirstDetailViewController alloc]init] autorelease];

    UINavigationController *rootNav=[[UINavigationController alloc]initWithRootViewController:rootViewController];
    UINavigationController *detailNav=[[UINavigationController alloc]initWithRootViewController:detailViewController];


    self.splitViewController.viewControllers=[NSArray arrayWithObjects:rootNav,detailNav,nil];
    self.splitViewController.delegate=self.detailViewController;

    // Add the split view controller's view to the window and display.
    [window addSubview:self.splitViewController.view];
    [window makeKeyAndVisible];
}

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


    self.navcon = [[UINavigationController alloc] init];
    self.menuViewController = [[MenuViewController alloc] init];
    self.menuViewController.appDelegate = self;
    [self.navcon pushViewController:self.menuViewController animated:NO];


    [window addSubview:self.menuViewController.view];
    [window makeKeyAndVisible];

    //[self useSplitViewController];

    return YES;
}

您需要设置窗口的根视图控制器：

替换

[window addSubview:self.splitViewController.view];

为，

[window setRootViewController:self.splitViewController];
