I want to fetch more data from server if the last cell will display, but UICollectionView don\'t have method -willDisplayCell like UITableview. So I have no idea about this
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).
