我有 spliteview 项目并在横向模式下强制它。在我将我的 iOS SDK 升级到 iOS6 之前它工作正常。但是升级后，当我使用 iOS 5.1 Simulator 运行时，它总是以纵向模式显示，并且主视图消失了。
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];
}
有任何想法吗？
我尝试为不同的版本提供不同的代码，在 iOS6 中似乎还可以，但在 iOS5.1 中，当我进入这个视图时仍然会改变方向，我想当我分配一个新的 UIWindow 时，它的原始方向是纵向的。
在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];
