在iOS 6 shouldAutorotateToInterfaceOrientation无法正常工作，但它的做工精细iOS 5.0或5.1 。

我应该需要改变什么iOS 6 。 这里是我的代码 

- (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;

}

当我搜索这个方位问题，我发现这一切

但对我来说没有什么工作:(请帮助.....

Answer 1:

编辑：这是发生，因为苹果已经改变了管理的定位方式UIViewController 。 在iOS6的方向以不同方式处理。 在iOS6的 shouldAutorotateToInterfaceOrientation方法已被弃用。 视图控制器（如UINavigationController ）不咨询自己的孩子，以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接口方向设置为UIInterfaceOrientationMaskAll为iPad 成语和UIInterfaceOrientationMaskAllButUpsideDown为iPhone成语。

如果你想有一个特定的视图改变为所需的方向，你必须做一些子类或类别和覆盖自转方法返回所需方向。

将这段代码放到你的根视图控制器。 这将有助于UIViewController ，以确定其方位。 

  //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，你需要实现以下的viewController方法（在iOS6的推出）的方向

- (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 
   }

并把你的代码下面的方法中。 当设备方向改变这个方法会被称为： 

 - (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，你需要在窗口中添加控制器rootViewController ，而不是addSubview像下面

self.window.rootViewController=viewController;

欲了解更多信息， 这里是关于iOS6.0 Beta 2的OTA的文章。

我希望这可以帮到你。



Answer 2:

我解决了这个问题的方法是替换下面的行，当我的应用程序在委托类开始

 window addSubview: navigationController.view

同

window.rootViewController = navigationController

我做了这个改变后，我的应用程序开始处理屏幕旋转



Answer 3:

这是因为苹果已经过时shouldautorate方法从iOS6的使用这些方法，而不是

- (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);


Answer 4:

我解决了这个问题，只需要使用这个

    - (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;
            }
            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;    
}


Answer 5:

请试试这个这将是对你有帮助。

在你的ViewController类编写代码

-(BOOL)shouldAutorotate
   {
      return YES;
   }

   -(NSUInteger)supportedInterfaceOrientations{
      return UIInterfaceOrientationMaskLandscape;
    }

然后，在搜索的appdelegate这一行[窗口addSubview：viewController.view]并用window.rootViewController =取代的viewController这;

欢呼声，将work.its为iOS 6的简单解决方案



Answer 6:

这个工作对我来说

- (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;
    }
