iphone – ViewController在UINavigationController方向更改

概述所以我有以下层次结构： UINavigationController – > RootViewController(UIViewController) – > UITableViewController – > DetailViewController(UIViewController) 我想将RootViewController上的方向锁定到“仅”纵向,但为其余视图控制器留下所有方向. 如果我把 所以我有以下层次结构：

UINavigationController – > RootVIEwController(UIVIEwController) – > UItableVIEwController – > DetailVIEwController(UIVIEwController)

我想将RootVIEwController上的方向锁定到“仅”纵向,但为其余视图控制器留下所有方向.

如果我把它放到子类UINavigationController中：

- (BOol)shouldautorotatetoInterfaceOrIEntation:(UIInterfaceOrIEntation)interfaceOrIEntation{    // Return YES for supported orIEntations    return (interfaceOrIEntation == UIInterfaceOrIEntationPortrait);}-(NSUInteger)supportedInterfaceOrIEntations{    return UIInterfaceOrIEntationMaskPortrait;}

所有视图控制器然后被锁定到纵向.

我的问题是,有没有办法只将RootVIEwController锁定到纵向,但是为其他视图控制器留下所有选项？

解决方法 检查在这里链接修复自动转换在iOS 6和设置方向支持每视图基础： http://www.disalvotech.com/blog/app-development/iphone/ios-6-rotation-solution/

这是你可以做的：

>在.m文件中创建一个作为UINavigationController子类的自定义导航控制器：

- (BOol)shouldautorotate {      return self.topVIEwController.shouldautorotate; } - (NSUInteger)supportedInterfaceOrIEntations {      return self.topVIEwController.supportedInterfaceOrIEntations; }

>在AppDelegate.h中,

@interface AppDelegate : UIResponder <UIApplicationDelegate> {      UINavigationController *navigationController;      VIEwController *vIEwController;  }  @property (strong,nonatomic) UIWindow *window;  @property (strong,nonatomic) VIEwController *vIEwController;

在AppDelegate.m中,

- (BOol)application:(UIApplication *)application dIDFinishLaunchingWithOptions:(NSDictionary *)launchOptions  {        // set initial vIEw       self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];       vIEwController = [[VIEwController alloc] initWithNibname:@"RootVIEwController" bundle:nil];       navigationController = [[CustomNavigationController alloc]                    initWithRootVIEwController:vIEwController]; // iOS 6 autorotation fix       [navigationController setNavigationbarHIDden:YES animated:NO];        self.window = [[UIWindow alloc]           initWithFrame:[[UIScreen mainScreen] bounds]];        [self.window setRootVIEwController:navigationController]; // iOS 6 autorotation fix        //[self.window addSubvIEw:navigationController.vIEw];        [self.window makeKeyAndVisible];         return YES;  }  - (NSUInteger)application:(UIApplication *)application supportedInterfaceOrIEntationsForWindow:(UIWindow *)window  // iOS 6 autorotation fix  {          return UIInterfaceOrIEntationMaskAll;  }

>在您的rootVIEwController中,无论什么事件推动第二个视图控制器,请执行以下 *** 作：

- (IBAction)pushSecondVIEwController:(ID)sender {    // push second vIEw controller    SecondVIEwController *secondVIEwController = [[SecondVIEwController alloc] initWithNibname:@"SecondVIEwController" bundle:nil];    [self.navigationController pushVIEwController:secondVIEwController animated:YES];   }

>在你的每个视图控制器,添加

- (BOol)shouldautorotate{}   - (NSUInteger)supportedInterfaceOrIEntations{}

对于iOS 6,您可以设置每个视图控制器,无论您想要单独的方向支持.

对于iOS 5及更低版本,您可以设置

- (BOol)shouldautorotatetoInterfaceOrIEntation:(UIInterfaceOrIEntation)interfaceOrIEntation{}

所有的学分都转交给John disalvo,他在链接中写了这个示例应用程序.

希望这可以帮助.
