无法停止设备旋转

我在这里发布了一个问题。 其中一个好友回答并给出了解决办法。 虽然这个解决scheme在很less的视图控制器上工作，但是看起来不行。 当我进入一个视图控制器的TabController +导航控制器的那里标签栏项目，代码不起作用。 和意见是能够旋转。

我使用iOS 6.1的以下代码

//For iOS6 - (BOOL)shouldAutorotate { return NO; } - (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation { return UIInterfaceOrientationPortrait; } - (NSUInteger)supportedInterfaceOrientations { return UIInterfaceOrientationMaskPortrait; } 

我也必须在iOS 7中实现同样的东西。 请帮忙

Answer 1

 shouldAutorotate, supportedInterfaceOrientations, preferredInterfaceOrientationForPresentation 

如果上述方法位于navigationcontroller任何tabbarcontroller ，则不会调用viewcontroller 。 如果这些方法是在tabbarcontroller或导航控制器中声明的，那么他们将被调用。

为了解决这个问题，创build了一个FixedOrientationTab类，它是UITabBarController一个子类，和一个导航类OrientationEnabledNavigation ，它是UINavigationController一个子类。 然后执行shouldAutorotate, supportedInterfaceOrientations, preferredInterfaceOrientationForPresentation方法在FixedOrientationTab和OrientationEnabledNavigation 。

OrientationEnabledNavigation.h

 #import <UIKit/UIKit.h> @interface OrientationEnabledNavigation : UINavigationController @end 

OrientationEnabledNavigation.m

 #import "OrientationEnabledNavigation.h" @interface OrientationEnabledNavigation () @end @implementation OrientationEnabledNavigation - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; if (self) { // Custom initialization } return self; } - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view. } - (BOOL)shouldAutorotate { return [self.topViewController shouldAutorotate]; // return NO; } - (NSUInteger)supportedInterfaceOrientations { return [self.topViewController supportedInterfaceOrientations]; } - (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation { return [self.topViewController preferredInterfaceOrientationForPresentation]; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. } @end 

FixedOrientationTab.h

 #import <UIKit/UIKit.h> @interface FixedOrientationTab : UITabBarController @end 

FixedOrientationTab.m

 #import "FixedOrientationTab.h" @interface FixedOrientationTab () @end @implementation FixedOrientationTab - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; if (self) { // Custom initialization } return self; } - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view. } - (BOOL)shouldAutorotate { return [self.selectedViewController shouldAutorotate]; // return NO; } - (NSUInteger)supportedInterfaceOrientations { return [self.selectedViewController supportedInterfaceOrientations]; } - (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation { return [self.selectedViewController preferredInterfaceOrientationForPresentation]; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. } @end 

然后，如果你想在你的项目中使用导航控制器，然后使用OrientationEnabledNavigation和tabbar FixedOrientationTab 。 之后，如果你实现了shouldAutorotate, supportedInterfaceOrientations, preferredInterfaceOrientationForPresentation这些方法在你的viewcontroller里面，那么他们会被调用。

希望这可以帮助.. ：）

编辑正如Jeev指出的另一种方式是添加一些代码开始您的应用程序委托：

对于UITabBarController

 @implementation UITabBarController (AutoRotationForwarding) -(BOOL)shouldAutorotate { if ([self.selectedViewController respondsToSelector:@selector(shouldAutorotate)]) { return [self.selectedViewController shouldAutorotate]; } else { return YES; } } - (NSUInteger)supportedInterfaceOrientations { if ([self.selectedViewController respondsToSelector:@selector(supportedInterfaceOrientations)]) { return [self.selectedViewController supportedInterfaceOrientations]; } else { return UIInterfaceOrientationMaskAll; } } @end 

对于UINavigationController

 @implementation UINavigationController (AutoRotationForwarding) -(BOOL)shouldAutorotate { if ([self.topViewController respondsToSelector:@selector(shouldAutorotate)]) { return [self.topViewController shouldAutorotate]; } else { return YES; } } -(NSUInteger) supportedInterfaceOrientations { if([self.topViewController respondsToSelector:@selector(supportedInterfaceOrientations)]) { return [self.topViewController supportedInterfaceOrientations]; } return UIInterfaceOrientationMaskPortrait; } @end 

Answer 2

我有UINavigationController包含UIViewController。

您应该通过子类UINavigationController禁用UINavigationController中的旋转并执行

 - (BOOL)shouldAutorotate { return YES; } - (NSUInteger)supportedInterfaceOrientations { // return some } - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation { // return some thing that you want } 

希望这可以帮助你。

由于我使用TabBarController，我得到的唯一工作解决scheme是创build一个类别。

所以只是做一个类别

这里是类的.h类，我把它命名为AutoRotationtab

 #import <UIKit/UIKit.h> #import "AppDelegate.h" @interface UITabBarController (AutoRotationTab) @end 

这里是类的.m类

 #import "UITabBarController+AutoRotationTab.h" @implementation UITabBarController (AutoRotationTab) -(BOOL)shouldAutorotate { if(globalvariable_shouldRotate) { return YES; } else { return NO; } } - (NSUInteger)supportedInterfaceOrientations { if(globalvariable_shouldRotate) { return UIInterfaceOrientationMaskAll; } else { return UIInterfaceOrientationMaskPortrait; } } 

只是做这个类别，看看魔术，它的作品
