iphone – iOS 6中视图控制器的旋转错误

基本上,这是帮助我的信息：

我必须在中设置window.rootViewController = mainViewController

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

2.对于视图控制器在哪里

- (BOOL)shouldAutorotateToInterfaceOrientation: (UIInterfaceOrientation)interfaceOrientation

不只是返回YES,我不得不补充

- (NSUInteger)supportedInterfaceOrientations

返回相同的值

3.补充说

- (BOOL)shouldAutorotate {
    return YES;
}

- (NSUInteger)supportedInterfaceOrientations {
    return (UIInterfaceOrientationMaskPorTrait | UIInterfaceOrientationMaskLandscapeLeft |
            UIInterfaceOrientationMaskLandscapeRight | UIInterfaceOrientationMaskPorTraitUpsideDown);
}

到mainViewController.m

4.补充说

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window {
    return (UIInterfaceOrientationMaskPorTrait | UIInterfaceOrientationMaskLandscapeLeft |
            UIInterfaceOrientationMaskLandscapeRight | UIInterfaceOrientationMaskPorTraitUpsideDown);
}

到appDelegate.m(我相信这是可选的,用于设置默认值,以防它们未在应用程序的Info.plist文件中或在单个视图控制器中指定)

由于我希望我的代码向后兼容回3.0,我没有使用All orientation mask,因为我需要使用XCode 4.3进行编译
