xcode shouldAutorotateToInterfaceOrientation 在 iOS 6 中不起作用

shouldAutorotateToInterfaceOrientation is not working in iOS 6

提问by Saif

In iOS?6, shouldAutorotateToInterfaceOrientationis not working, but it worked fine in iOS?5.0 and?5.1.

在 iOS?6 中，shouldAutorotateToInterfaceOrientation不工作，但在 iOS?5.0 和?5.1 中工作正常。

What do I need to change for iOS?6? Here is my?code:

我需要为 iOS 更改什么？6？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;    
}

When I searched for this orientation problem, all I found was thisand this, but nothing worked for me :(

当我搜索这个方向问题时，我发现的只是这个和这个，但对我来说没有任何作用:(

Please help .....

请帮忙 .....

EDIT:This is happening because Apple has changed the way of managing the Orientation of UIViewController. In iOS6 orientation handles differently. In iOS6shouldAutorotateToInterfaceOrientationmethod is deprecated. View controllers (such as UINavigationController) do not consult their children to determine whether they should autorotate. By default, an app and a view controller's supported interface orientations are set to UIInterfaceOrientationMaskAllfor the iPad idiomand UIInterfaceOrientationMaskAllButUpsideDownfor the iPhone idiom.

编辑：发生这种情况是因为 Apple 改变了管理UIViewController. 在 iOS6 方向处理不同。在iOS6 中shouldAutorotateToInterfaceOrientation方法已弃用。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。

If you want a specific view to be changed to the desired orientation you have to do some sort of subclass or category and override the autorotation methods to return the desired orientation.

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。

Place this code in your root view controller. This will help the UIViewControllerto determine its orientation.

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

Now you need to implement below methods (introduced in iOS6) in viewController for orientation

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

- (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 
   }

And put your code inside the below method. Whenever device orientation is changed this method will be called:

并将您的代码放在下面的方法中。每当设备方向更改时，将调用此方法：

 - (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;
    }                
  }    

Edit:check your window, you need to add the controller on window as rootViewControllerrather than addSubviewlike below

编辑：检查您的窗口，您需要在窗口上添加控制器，rootViewController而不是addSubview像下面那样

self.window.rootViewController=viewController;

For more information here's an article about iOS6.0 Beta 2 OTA.

I hope this was helpful.

The way I fixed this problem was to replace the following line when my app starts in Delegate Class

我解决这个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

with

和

window.rootViewController = navigationController

After I made this change my app started to handle screen rotations

进行此更改后，我的应用程序开始处理屏幕旋转

回答by Saad

This is because Apple has deprecated shouldautorate method from ios6 use these methods instead

这是因为 Apple 已经弃用了 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);

I Solved this problem just use this

please try this one it will be helpful for you.

请试试这个，它会对你有帮助。

write code in you viewcontroller class

在您的视图控制器类中编写代码

-(BOOL)shouldAutorotate
   {
      return YES;
   }

   -(NSUInteger)supportedInterfaceOrientations{
      return UIInterfaceOrientationMaskLandscape;
    }

Then in appdelegate search this line [window addSubview:viewController.view] and replace this with window.rootViewController = viewController;

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

cheers it will work.its simple solution for ios 6

this worked for me

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;
    }
