今天做到5s打开自定义相机时 取景无法全屏问题 如下图
添加以下代码可以解决问题 将取景框变成全屏
{
CGSize screenBounds = [UIScreen mainScreen].bounds.size;
CGFloat cameraAspectRatio = 4.0f/3.0f;
CGFloat camViewHeight = screenBounds.width * cameraAspectRatio;
CGFloat scale = screenBounds.height / camViewHeight;
pickerController.cameraViewTransform = CGAffineTransformMakeTranslation(0, (screenBounds.height - camViewHeight) / 2.0);
pickerController.cameraViewTransform = CGAffineTransformScale(pickerController.cameraViewTransform, scale, scale);
}
