關於tableview的移動，apple提供了官方的做法，但是無法做擴充套件，生成的cell往往不符合實際需求，所以這裡提供自定義移動操作：

//為tableview新增對應的手勢來模擬移動手勢。
UILongPressGestureRecognizer* longPressGesture=[[UILongPressGestureRecognizer alloc]initWithTarget:self action:@selector(handlerLongPress:)];
longPressGesture.minimumPressDuration=0.5;
[_sortTableView addGestureRecognizer:longPressGesture];


-(void
 
)handlerLongPress:(UILongPressGestureRecognizer*)sender{
    switch (sender.state) {
        case UIGestureRecognizerStateBegan:
            [self handlerLongPressBegan:sender];
            break;

        case UIGestureRecognizerStateChanged:
            [self handlerLongPressChanged:sender];
            break
 
;
        case UIGestureRecognizerStateCancelled:
            [self handlerLongPressEnded:sender];
            break;
        case UIGestureRecognizerStateEnded:
            [self handlerLongPressEnded:sender];
            break;
        default:
            break;
    }
}

-(void)handlerLongPressBegan:(UILongPressGestureRecognizer*)longPressGesture{
    //手勢識別開始階段獲取對應的觸碰位置.
 

    CGPoint location=[longPressGesture locationInView:_sortTableView];
    NSIndexPath* indexPath=[_sortTableView indexPathForRowAtPoint:location];

    //判斷觸碰位置是否為tableview的某一行
    if(indexPath){
          //_sourceIndexPath為屬性變數用於儲存初始被移動的cell的位置。
        _sourceIndexPath=indexPath;
        //獲取cell
        QTShortcutsListenSortTableCell* cell=[_sortTableView cellForRowAtIndexPath:indexPath];
        //對cell進行截圖並儲存到屬性變數
        _snapshot=[cell resizableSnapshotViewFromRect:CGRectMake(0, 0, cell.frame.size.width, 50) afterScreenUpdates:NO withCapInsets:UIEdgeInsetsZero];
        //得到初始位置的cell的中心。然後隱藏cell，並將截圖放到cell對應的位置，用此截圖來假裝一個cell來拖動。
        CGPoint center=cell.center;
        [_sortTableView addSubview:_snapshot];
        center.y=location.y;
        _snapshot.center=center;
        _snapshot.transform=CGAffineTransformMakeScale(1, 1);
        _snapshot.alpha=1;
        _snapshot.backgroundColor=cell.backgroundColor;
        cell.backgroundColor=[UIColor clearColor];
        cell.hidden=true;

    }
}

-(void)handlerLongPressChanged:(UILongPressGestureRecognizer*)longPressGesture{
    //當手勢改變的時候，獲取所處的位置，然後一步步交換截圖以及對應的cell和相對應的資料。
    CGPoint location=[longPressGesture locationInView:_sortTableView];
    NSIndexPath* indexPath=[_sortTableView indexPathForRowAtPoint:location];
    CGPoint center=_snapshot.center;
    center.y=location.y;
    _snapshot.center=center;

    if(indexPath&&![indexPath isEqual:_sourceIndexPath]){
        //這裡的_sortModelArr對應著資料模型陣列
        QTShortcutsListenSortModel* modelToMove=_sortModelArr[_sourceIndexPath.row];
        [_sortModelArr removeObjectAtIndex:_sourceIndexPath.row];
        [_sortModelArr insertObject:modelToMove atIndex:indexPath.row];
        [_sortTableView moveRowAtIndexPath:_sourceIndexPath toIndexPath:indexPath];
        _sourceIndexPath=indexPath;
    }
}

-(void)handlerLongPressEnded:(UILongPressGestureRecognizer*)longPressGesture{
    QTShortcutsListenSortTableCell* cell=[_sortTableView cellForRowAtIndexPath:_sourceIndexPath];
    //手勢結束以後，將截圖置為nil，將原來的cell展示出來。
    [UIView animateWithDuration:0.25 animations:^{
        _snapshot.center=cell.center;
        _snapshot.transform=CGAffineTransformIdentity;
        _snapshot.alpha=0;
        cell.backgroundColor=_snapshot.backgroundColor;
        cell.hidden=false;
    } completion:^(BOOL finished) {
        [_snapshot removeFromSuperview];
        _snapshot=nil;
    }];
    _sourceIndexPath=nil;
}
