{
    return self.dataArray.count;
}

- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
    LxGridViewCell * cell = [collectionView dequeueReusableCellWithReuseIdentifier:LxGridViewCellReuseIdentifier forIndexPath:indexPath];
    
    cell.delegate = self;
    cell.editing = _gridView.editing;
    
    //	...	config cell
    
    return cell;
}

- (void)collectionView:(UICollectionView *)collectionView itemAtIndexPath:(NSIndexPath *)sourceIndexPath willMoveToIndexPath:(NSIndexPath *)destinationIndexPath
{
    NSDictionary * dataDict = self.dataArray[sourceIndexPath.item];
    [self.dataArray removeObjectAtIndex:sourceIndexPath.item];
    [self.dataArray insertObject:dataDict atIndex:destinationIndexPath.item];
}

- (void)deleteButtonClickedInGridViewCell:(LxGridViewCell *)gridViewCell
{
    NSIndexPath * gridViewCellIndexPath = [_gridView indexPathForCell:gridViewCell];
    
    if (gridViewCellIndexPath) {
        [self.dataArray removeObjectAtIndex:gridViewCellIndexPath.item];
        [_gridView performBatchUpdates:^{
            [_gridView deleteItemsAtIndexPaths:@[gridViewCellIndexPath]];
        } completion:nil];
