自定義相機全屏 記錄一下

CGSize size = [UIScreen mainScreen].bounds.size;

CGFloat cameraAspectRatio = 4.0f/3.0f;

CGFloat camViewHeight = size.width * cameraAspectRatio;

CGFloat scale = size.height / camViewHeight;

pickerController.cameraViewTransform = CGAffineTransformMakeTranslation(0, (size.height - camViewHeight) / 2.0);

pickerController.cameraViewTransform = CGAffineTransformScale(pickerController.cameraViewTransform, scale, scale);
