iPhone的“相机重叠”视图未在横向模式下显示

Question

我已经使用UIImagePickerViewController启动了相机并尝试覆盖另一个视图。 我已经为“风景”模式设置了“叠加”视图，但是在叠加到“相机”视图后，它仍以“人像”模式显示。

Answer 1

我已经解决了这个问题，方法是旋转叠加视图，如下所示：tmpCamera.cameraOverlayView.transform = CGAffineTransformRotate（CGAffineTransformIdentity，117.81）; 希望这可以节省一些时间:)

   first you selected only potrait mode in app settting
then use this function in viewdidLoad
//Orientation View into LandScape Mode
    -(void)orientationToLandscape{
        CGAffineTransform rotateTransform;
        switch ([UIApplication sharedApplication].statusBarOrientation) {
            case UIInterfaceOrientationPortrait:
                rotateTransform = CGAffineTransformMakeRotation(-90*M_PI/180.0);
                break;
            case UIInterfaceOrientationPortraitUpsideDown:
                rotateTransform = CGAffineTransformMakeRotation(90*M_PI/180.0);
                break;

            default:
                rotateTransform = CGAffineTransformMakeRotation(0);
                break;
        }

        rotateTransform = CGAffineTransformTranslate(rotateTransform, +90.0, +90.0);
        [self.view setTransform:rotateTransform];


    }
