UITableview称重传感器长期Swift-需要建议调整

请参考附件中的代码以及图片中的代码。我需要你的建议我怎样才能更快地装货

哇，为什么在单元格创建中使用

dispatch\u async（dispatch\u get\u main\u queue（），{（）->Void）呢？不必。删除此方法，代码应该如下所示：

override func tableView(tableView: UITableView?, cellForRowAtIndexPath indexPath: NSIndexPath?) -> UITableViewCell {
let wishRow = self.wishDataList.objectAtIndex(indexPath!.row) as! NSMutableArray
println(userImageList.count)
switch (wishRow).count{

case 4:

    let cell = tableView!.dequeueReusableCellWithIdentifier("CellHeader", forIndexPath: indexPath!) as! WishHeaderTableViewCell
        let dateFormatter = NSDateFormatter()
        cell.LblCity.text = wishRow[1] as? String
        cell.ImgAddWish.layer.cornerRadius = 20
        cell.ImgAddWish.clipsToBounds = true
        cell.ImgAddWish.autoresizesSubviews = false
        //           cell.ImageViewTripOwner.layer.cornerRadius = 20
        //           cell.ImageViewTripOwner.clipsToBounds = true
        cell.ImageViewTripOwner.autoresizesSubviews = false
        for object in self.userImageList{
            if object[0] as? String == (wishRow[3] as? PFUser)?.objectId{

                cell.ImageViewTripOwner.image = UIImage(data: (object[1] as! PFFile).getData()!)

                //SharedFunction.imageResize(UIImage(data: (object[1] as PFFile).getData())!, sizeChange: CGSize(width: 40, height: 40))
            }
        }

    return cell
