int saveGifToGallery(const char *path0){

    NSString *path = [NSString stringWithUTF8String:path0];
    NSData *data = [NSData dataWithContentsOfFile:path];
    [[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{
        PHAssetResourceCreationOptions *options = [[PHAssetResourceCreationOptions alloc] init];
        [[PHAssetCreationRequest creationRequestForAsset] addResourceWithType:PHAssetResourceTypePhoto data:data options:options];
