Iphone UIImagePickerController方向
我正在使用自定义覆盖视图为全屏相机创建一个Iphone UIImagePickerController方向,iphone,objective-c,xcode,overlay,uiimagepickercontroller,Iphone,Objective C,Xcode,Overlay,Uiimagepickercontroller,我正在使用自定义覆盖视图为全屏相机创建一个UIImagePickerController，但每次旋转设备时，我都会收到一个错误，上面写着“CGAffineTransformInvert:singular matrix.”作为我如何进行此操作的参考，我将遵循本教程：以下是旋转相机覆盖视图的代码 cameraOverlayView.transform = CGAffineTransformMakeRotation(-3.141592/2); 它用于缩放变换： cameraOverlayView.t
UIImagePickerControllerCGAffineTransformInvert:singular matrix.cameraOverlayView.transform = CGAffineTransformMakeRotation(-3.141592/2);
cameraOverlayView.transform = CGAffineTransformMakeRotation(-3.141592/2);
cameraController.cameraViewTransform=CGAffineTransformScale(cameraController.cameraViewTransform, 1, 1.25);
