you can also use the scrollview delegate since uicollectionview inherits from uiscrollview , just implement the uiscrollview delegate method : 

- (void)scrollViewDidScroll:(UIScrollView *)scrollView;

and do something like : 

- (void)scrollViewDidScroll:(UIScrollView *)scrollView{
    if (scrollView.contentOffset.y == scrollView.contentSize.height - scrollView.frame.size.height)
    {
      //LOAD MORE
      // you can also add a isLoading bool value for better dealing :D
   }
}

You can simply implement the fetching operation inside - 

  (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath

and check for the condition 

 if(indexPath.row==your_array.count-1).
