You may use the following code just change the name of album :

__weak ALAssetsLibrary *lib = self.library;

[self.library addAssetsGroupAlbumWithName:@"My Photo Album" resultBlock:^(ALAssetsGroup *group) {

    ///checks if group previously created
    if(group == nil){

        //enumerate albums
        [lib enumerateGroupsWithTypes:ALAssetsGroupAlbum
                           usingBlock:^(ALAssetsGroup *g, BOOL *stop)
         {
             //if the album is equal to our album
             if ([[g valueForProperty:ALAssetsGroupPropertyName] isEqualToString:@"My Photo Album"]) {

                 //save image
                 [lib writeImageDataToSavedPhotosAlbum:UIImagePNGRepresentation(image) metadata:nil
                                       completionBlock:^(NSURL *assetURL, NSError *error) {

                                           //then get the image asseturl
                                           [lib assetForURL:assetURL
                                                resultBlock:^(ALAsset *asset) {
                                                    //put it into our album
                                                    [g addAsset:asset];
                                                } failureBlock:^(NSError *error) {

                                                }];
                                       }];

             }
         }failureBlock:^(NSError *error){

         }];

    }else{
        // save image directly to library
        [lib writeImageDataToSavedPhotosAlbum:UIImagePNGRepresentation(image) metadata:nil
                              completionBlock:^(NSURL *assetURL, NSError *error) {

                                  [lib assetForURL:assetURL
                                       resultBlock:^(ALAsset *asset) {

                                           [group addAsset:asset];

                                       } failureBlock:^(NSError *error) {

                                       }];
                              }];
    }
