如何更改相机Overlayview方向横向左右iPhone？

Question

在我的iPhone应用程序中,我有一个用于拍照的UIImagePickerController.我隐藏了所有默认的相机控件,并在UIImagePickerController中添加了带有两个按钮的UIView作为CameraOverLayView.我的应用程序始终只在横向模式下运行.相机也仅启动横向模式.现在,CameraOverlayView仅在Landscape左侧不变为Landscape to Right.当设备方向改变时,如何左右更改CameraOverlayView LandscapeMode？请帮我修理一下.这是我的应用程序中的主要问题.此代码在横向模式下保持Overlayview为Left

imgpicker.cameraOverlayView.transform = CGAffineTransformRotate(CGAffineTransformIdentity, 117.81);

并且此代码在横向模式下保持cameraoverlayview权限GAffineTransform transform = self.view.transform;

    transform = CGAffineTransformRotate(transform, (M_PI / 2.0));

    imgpicker.cameraOverlayView.transform = transform;

我在这样的UIInterfaceOrientation方法中使用了这些代码,

UIInterfaceOrientation orientation= [[UIApplication sharedApplication] statusBarOrientation];
    if (orientation == UIInterfaceOrientationLandscapeLeft) 
    {
        imgpicker.cameraOverlayView.transform = CGAffineTransformRotate(CGAffineTransformIdentity, 117.81);
    }
    else if (orientation == UIInterfaceOrientationLandscapeRight)
    {
        CGAffineTransform transform = self.view.transform;
            transform = CGAffineTransformRotate(transform, (M_PI / 2.0));
        imgpicker.cameraOverlayView.transform = transform;
    }

但是,这些并没有帮助我.当我左右旋转设备方向横向时,相机覆盖视图不会改变.你能解决我的问题吗？谢谢.

谢谢大家.我自己解决了Camera OverlayView方向问题.我使用了我的问题中提到的相同代码.我已经为方向更改添加了UIDeviceOrientation Notification.请找到下面的代码,

[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(orientationChanged:) name:@"UIDeviceOrientationDidChangeNotification" object:nil];


- (void) orientationChanged:(NSNotification *)notification
{
    UIDeviceOrientation orientation = [[UIDevice currentDevice] orientation];
if(orientation == UIDeviceOrientationLandscapeLeft)
        {                  
            CGAffineTransform transform = self.view.transform;
            transform = CGAffineTransformRotate(transform, (M_PI/2.0));
            imgpicker.cameraOverlayView.transform = transform;
        } 
        else if(orientation == UIDeviceOrientationLandscapeRight) 
        {   
            imgpicker.cameraOverlayView.transform = CGAffineTransformRotate(CGAffineTransformIdentity,117.81);
        }  
}

我刚刚在我的代码中添加了此方法.因此,当用户更改设备方向时,此方法将调用并更改相机覆盖视图的方向.请检查此方法中的条件,否则应用程序将崩溃.谢谢.
