Question

我有一个UINavigationController呈现了几个UIViewControllers。然后我想切换到UISplitviewController。

所以我在app-Delegate中实现了一个方法useSplitViewController，我从上一个UIViewController调用了该方法。它显示SplitView，但我无法旋转设备。我的ViewController中的SplitviewController s不会获得旋转事件。我的错误是什么？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];

用，

[window setRootViewController:self.splitViewController];

从UINavigationController切换到UISplitviewController
