在 iOS 6shouldAutorotateToInterfaceOrientation中无法正常工作，但在 iOS 5.0 和 5.1 中运行良好。

对于 iOS 6，我需要更改哪些内容？这是我的代码：

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
if([[[SampleApplicationAppDelegate instance].callInfoDictionary valueForKey:IS_CHAT] isEqualToString:NO_RESPONSE])
{
    int nAngle = 0;
    BOOL bRet = NO;
    
    switch (interfaceOrientation) {
        case UIInterfaceOrientationPortrait:
            nAngle = 90;
            bRet = YES;
            NSLog(@".......Preview = %f %f",_previewCamera.frame.size.width,_previewCamera.frame.size.height);
            
            _previewCamera.transform = CGAffineTransformMakeRotation(M_PI*1.5);
            
            NSLog(@"Preview = %f %f",_previewCamera.frame.size.width,_previewCamera.frame.size.height);
            break;
            
        case UIInterfaceOrientationPortraitUpsideDown:
            nAngle = 270;
            bRet = YES;
            _previewCamera.transform = CGAffineTransformMakeRotation(M_PI_2);
            break;
            
        case UIInterfaceOrientationLandscapeLeft:
            nAngle = 0;
            bRet = YES;
            //_previewCamera.transform = CGAffineTransformMakeRotation(M_PI*1.5);
            break;
            
        case UIInterfaceOrientationLandscapeRight:
            nAngle = 180;
            bRet = YES;
            //_previewCamera.transform = CGAffineTransformMakeRotation(M_PI_2);
            break;
            
        default:
            break;
    }                
    return bRet;
}    
if(interfaceOrientation == UIInterfaceOrientationPortrait || interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown)
    return YES;     
return NO;    
}

当我搜索这个方向问题时，我发现的只有这个和这个，但对我没有任何帮助:(

请帮忙 .....

编辑：发生这种情况是因为 Apple 改变了管理UIViewController. 在 iOS6 中，方向处理方式不同。在iOS6 中， shouldAutorotateToInterfaceOrientation方法已被弃用。视图控制器（例如UINavigationController）不会咨询他们的孩子来确定他们是否应该自动旋转。默认情况下，应用程序和视图控制器支持的界面方向设置UIInterfaceOrientationMaskAll为 iPad惯用语和UIInterfaceOrientationMaskAllButUpsideDowniPhone 惯用语。

如果您希望将特定视图更改为所需的方向，您必须执行某种子类或类别并覆盖自动旋转方法以返回所需的方向。

将此代码放在您的根视图控制器中。这将有助于UIViewController确定其方向。

  //RotationIn_IOS6 is a Category for overriding the default orientation.

  @implementation UINavigationController (RotationIn_IOS6)

 -(BOOL)shouldAutorotate
    {
      return [[self.viewControllers lastObject] shouldAutorotate];
    }

  -(NSUInteger)supportedInterfaceOrientations
   {
     return [[self.viewControllers lastObject] supportedInterfaceOrientations];
   }

 - (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
 {
     return [[self.viewControllers lastObject]  preferredInterfaceOrientationForPresentation];
 }

 @end

现在您需要在 viewController 中实现以下方法（在 iOS6 中引入）以进行定位

- (BOOL)shouldAutorotate
{
    //returns true if want to allow orientation change
    return TRUE;


}
- (NSUInteger)supportedInterfaceOrientations
{   
     //decide number of origination tob supported by Viewcontroller.
     return UIInterfaceOrientationMaskAll;


}

 - (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
   {
     //from here you Should try to Preferred orientation for ViewController 
   }

并将您的代码放入以下方法中。每当更改设备方向时，都会调用此方法：

 - (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)  interfaceOrientation duration:(NSTimeInterval)duration
{
if([[[SampleApplicationAppDelegate instance].callInfoDictionary valueForKey:IS_CHAT] isEqualToString:NO_RESPONSE])
{
    int nAngle = 0;
    BOOL bRet = NO;

    switch (interfaceOrientation) {
        case UIInterfaceOrientationPortrait:
            nAngle = 90;
            bRet = YES;
            NSLog(@".......Preview = %f %f",_previewCamera.frame.size.width,_previewCamera.frame.size.height);

            _previewCamera.transform = CGAffineTransformMakeRotation(M_PI*1.5);

            NSLog(@"Preview = %f %f",_previewCamera.frame.size.width,_previewCamera.frame.size.height);
            break;

        case UIInterfaceOrientationPortraitUpsideDown:
            nAngle = 270;
            bRet = YES;
            _previewCamera.transform = CGAffineTransformMakeRotation(M_PI_2);
            break;

        case UIInterfaceOrientationLandscapeLeft:
            nAngle = 0;
            bRet = YES;
            //_previewCamera.transform = CGAffineTransformMakeRotation(M_PI*1.5);
            break;

        case UIInterfaceOrientationLandscapeRight:
            nAngle = 180;
            bRet = YES;
            //_previewCamera.transform = CGAffineTransformMakeRotation(M_PI_2);
            break;

        default:
            break;
    }                
  }

编辑：检查你的窗口，你需要在窗口上添加控制器，rootViewController而不是addSubview像下面这样

self.window.rootViewController=viewController;

有关详细信息，请参阅有关iOS6.0 Beta 2 OTA 的文章。

我希望这可以帮到你。

我解决此问题的方法是在我的应用程序在委托类中启动时替换以下行

 window addSubview: navigationController.view

和

window.rootViewController = navigationController

进行此更改后，我的应用程序开始处理屏幕旋转

这是因为 Apple 已弃用 ios6 中的 shouldautorate 方法，而是使用这些方法

- (BOOL)shouldAutorotate NS_AVAILABLE_IOS(6_0);
- (NSUInteger)supportedInterfaceOrientations NS_AVAILABLE_IOS(6_0);
// Returns interface orientation masks.
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation NS_AVAILABLE_IOS(6_0);

我解决了这个问题就用这个

    - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {    
    if(![AppDelegate instance])
        return (interfaceOrientation == UIInterfaceOrientationPortrait) || (interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown);

    if([[[AppDelegate instance].callInfoDictionary valueForKey:IS_CHAT] isEqualToString:NO_RESPONSE])
    {
        int nAngle = 0;
        BOOL bRet = NO;

        switch (interfaceOrientation) {
            case UIInterfaceOrientationPortrait:
            {
                nAngle = 90;
                bRet = YES;
                NSLog(@".......Preview = %f %f",_previewCamera.frame.size.width,_previewCamera.frame.size.height);

                NSComparisonResult order = [[UIDevice currentDevice].systemVersion compare: @"6.0" options: NSNumericSearch];
                if (order == NSOrderedSame || order == NSOrderedDescending)
                {
                    // OS version >= 6.0
                    NSLog(@"ami iOS 6 er device");
                    _previewCamera.transform = CGAffineTransformMakeRotation(M_PI_2);
                }
                else
                {
                    // OS version < 6.0
                    _previewCamera.transform = CGAffineTransformMakeRotation(M_PI*1.5);
                }

                NSLog(@"Preview = %f %f",_previewCamera.frame.size.width,_previewCamera.frame.size.height);
                NSLog(@"-->%s %d",__FUNCTION__,__LINE__);
                break;
            }

            case UIInterfaceOrientationPortraitUpsideDown:
            {

                nAngle = 270;
                bRet = YES;
                NSComparisonResult order = [[UIDevice currentDevice].systemVersion compare: @"6.0" options: NSNumericSearch];
                if (order == NSOrderedSame || order == NSOrderedDescending)
                {
                    // OS version >= 6.0
                    NSLog(@"ami iOS 6 er device");
                    _previewCamera.transform = CGAffineTransformMakeRotation(M_PI*1.5);
                }
                else
                {
                    // OS version < 6.0
                    _previewCamera.transform = CGAffineTransformMakeRotation(M_PI_2);
                }
                break;
            }

                //_previewCamera.transform = CGAffineTransformMakeRotation(M_PI*1.5);
                break;

            case UIInterfaceOrientationLandscapeRight:

请试试这个，它会对你有所帮助。

在你的 viewcontroller 类中编写代码

-(BOOL)shouldAutorotate
   {
      return YES;
   }

   -(NSUInteger)supportedInterfaceOrientations{
      return UIInterfaceOrientationMaskLandscape;
    }

然后在 appdelegate 中搜索这一行 [window addSubview:viewController.view] 并将其替换为 window.rootViewController = viewController;

欢呼它会起作用。它适用于 ios 6 的简单解决方案

这对我有用

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations
    return [super shouldAutorotateToInterfaceOrientation:interfaceOrientation];
}


    - (BOOL)shouldAutorotate {

        UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation];

        if (orientation == UIInterfaceOrientationPortrait) {
            // your code for portrait mode

        }

        return YES;
    }
    - (NSUInteger)supportedInterfaceOrientations
    {
        return UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskLandscapeLeft | UIInterfaceOrientationMaskLandscapeRight | UIInterfaceOrientationMaskPortraitUpsideDown;
    }
