Here is an example of code how you can write/save image to Photo Library using UIImageWriteToSavedPhotosAlbum function:

- (void)saveImage:(UIImage *)image {
    UIImageWriteToSavedPhotosAlbum(self.image, self, @selector(image:didFinishSavingWithError:contextInfo:), NULL);
}
- (void)image:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo;
{
    if (!error) {
        // saved successfully

        PHFetchOptions *fetchOptions = [PHFetchOptions new];
        fetchOptions.sortDescriptors = @[[NSSortDescriptor sortDescriptorWithKey:@"creationDate" ascending:NO]];
        PHAsset *asset = [PHAsset fetchAssetsWithMediaType:PHAssetMediaTypeImage options:fetchOptions].firstObject;
        if (asset != nil) {
            // here you can use asset of your image
        }
    } else {
        NSLog(@"save image error: %@", error);
    }
}

Don't forget to add into your Info.plist a key-value pair Privacy - Camera Usage Description with description of usage.
