ios splitviewcontroller景观失败

Question

我有spliteview项目并强制它以横向模式。 在我将iOS SDK升级到iOS6之前，它工作正常。 但升级后，当我使用iOS 5.1模拟器运行时，它总是以纵向模式显示，主视图不见了。

这是我的代码：

- (void)viewDidLoad
{
    [super viewDidLoad];

    self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];

    MasterViewController *masterViewController = [[[MasterViewController alloc] initWithNibName:@"MasterViewController" bundle:nil] autorelease];
    UINavigationController *masterNavigationController = [[[UINavigationController alloc] initWithRootViewController:masterViewController] autorelease];

    CustomverDetailViewController *custView = [[[CustomverDetailViewController alloc] initWithNibName:@"CustomverDetailViewController" bundle:nil] autorelease];

    self.splitViewController = [[[UISplitViewController alloc] init] autorelease];
    self.splitViewController.viewControllers = @[masterNavigationController, custView];


    self.window.rootViewController = self.splitViewController;

    [self.window makeKeyAndVisible];
}

有什么想法吗？

我尝试为不同的版本提供不同的代码，在iOS6中似乎没问题，但是在我进入此视图时iOS5.1仍然会改变方向，我想当我分配一个新的UIWindow时，它的原始方向是肖像。 / p>

这里我改变了我的代码：

self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];

left = [[[MasterViewController alloc] initWithNibName:@"MasterViewController" bundle:nil] autorelease];
UINavigationController *masterNavigationController = [[[UINavigationController alloc] initWithRootViewController:left] autorelease];


right = [[CustomverDetailViewController alloc] initWithNibName:@"CustomverDetailViewController" bundle:nil];


self.splitViewController = [[[UISplitViewController alloc] init] autorelease];
self.splitViewController.viewControllers = @[masterNavigationController, right];


if (([[[UIDevice currentDevice] systemVersion] floatValue ] < 6.0 )) {


    self.splitViewController.delegate = left;
    [self.splitViewController.view setFrame:CGRectMake(0, 0, 1024.0f, 768.0f)];

    self.window.rootViewController = self.splitViewController;
     [self.window makeKeyAndVisible];


}else{
    self.window.rootViewController = self.splitViewController;
    [self.window makeKeyAndVisible];
}

[right release];

尝试添加在iOS 6中添加的新委托方法

- (NSUInteger)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskLandscape;
}

- (void)shouldAutorotate {
    return NO;
}
