_gridView = LxGridView(frame: GRIDVIEW_FRAME, collectionViewLayout: _gridViewFlowLayout)
//	...	congif _gridView

_gridView.registerClass(LxGridViewCell.classForCoder(), forCellWithReuseIdentifier: GRIDVIEW_CELL_REUSE_IDENTIFIER)

//	implement delegate method
func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {

    return dataArray.count
}

func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {

    let cell = collectionView.dequeueReusableCellWithReuseIdentifier(LxGridViewCellReuseIdentifier, forIndexPath: indexPath) as! LxGridViewCell
    
    cell.delegate = self
    cell.editing = _gridView.editing
    
    //	...	config cell
    
    return cell
}

func collectionView(collectionView: LxGridView, itemAtIndexPath sourceIndexPath: NSIndexPath, willMoveToIndexPath destinationIndexPath: NSIndexPath) {
    
    let dataDict = dataArray[sourceIndexPath.item]
    dataArray.removeAtIndex(sourceIndexPath.item)
    dataArray.insert(dataDict, atIndex: destinationIndexPath.item)
}

func deleteButtonClickedInGridViewCell(gridViewCell: LxGridViewCell) {

    if let gridViewCellIndexPath = _gridView!.indexPathForCell(gridViewCell) {
    
        dataArray.removeAtIndex(gridViewCellIndexPath.item)
        _gridView.performBatchUpdates({ [unowned self] () -> Void in
            self._gridView.deleteItemsAtIndexPaths([gridViewCellIndexPath])
        }, completion: nil)
    }
}
