iOS 13-以错误的方向保存UIImage

Question

我在照片方向方面遇到了一些问题。 拍摄人像照片并将其保存到相机胶卷后，我看到它旋转了。但是，当我将其添加到图像视图时，它看起来还可以。 其他人发现了同样的问题吗？反馈助手中是否存在打开的错误？ 谢谢！

当我尝试使用PHPhotoLibrary保存它时发生了同样的问题

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];
    UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil); //Saves rotated
    imageView.image = image; //Appears OK
    [self dismissModalViewControllerAnimated:YES];
}

PHAssetChangeRequest *changeRequest = [PHAssetChangeRequest creationRequestForAssetFromImage:image];
assetPlaceholder = changeRequest.placeholderForCreatedAsset;

我的项目中有这个扩展名。试试吧。

extension UIImage {
    func fixOrientation() -> UIImage {
        if imageOrientation == .up {
            return self
        }
        UIGraphicsBeginImageContextWithOptions(size, false, scale)
        draw(in: CGRect(origin: .zero, size: size))
        let normalizedImage: UIImage = UIGraphicsGetImageFromCurrentImageContext() ?? self
        UIGraphicsEndImageContext()
        return normalizedImage
    }
}
