Question

我试图在表视图单元格上滑动删除，但是在刷过该单元格数次后，只有它被删除。如何使其顺利工作（一次尝试滑动和删除）？我的代码在这里：

SELECT COUNT(*) AS `doubles` FROM [table] GROUP BY `Kanji` HAVING `doubles` > 1;

首先，我想指出你在错误的地方展示警报。成功后，您在API上进行删除调用，询问他或她是否想要确认。你必须在致电删除之前询问它

func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {

var bId = Helper.businessId as String
let param = ["id" : bId] as! [String : AnyObject]
if editingStyle == .delete{
    print(Helper.memId)
    print("Deleted")

var myDictionary = self.List[indexPath.row] as! NSDictionary
var bId : String!

if myDictionary.allKeys.count>0
{
    bId = myDictionary["id"] as! String
}
var bb = bId as String
        if editingStyle == .delete{
    print(Helper.memId)
    print("Deleted")

             let myAlert = UIAlertController(title:"Alert", message: "Do You want to delete",preferredStyle:UIAlertControllerStyle.alert)
             let okAction = UIAlertAction(title:"Ok",style:UIAlertActionStyle.default,handler:{ (action: UIAlertAction!) in
                   // here you can call the delete if user accepts
                    Alamofire.request("http://api.noattabeta.com/api/v1/user/current/memberships/\(bb)", method: .delete, headers: ["Authorization":Helper.token]).responseString
        {response in
            print("In Response")

            switch response.result {
            case .success:

                   DispatchQueue.main.async {

                      // remove from your local array e.g
                      self.dataModel.remove(at: indexPath.row)
                      // Delete the row before you reload the tableView
                      self.tableView.deleteRows(at: [indexPath], with: .automatic)               
                      // Now reload your tableView
                      self.tableView.reloadData()
                    }
            case .failure(let error):
                print(error)
              })

             myAlert.addAction(okAction)
            let cancelAction = UIAlertAction(title:"Cancel",style:UIAlertActionStyle.default,handler:{ (action: UIAlertAction!) in
                     self.tableView.reloadData()
              })

               myAlert.addAction(okAction)
               myAlert.addAction(cancelAction)

               self.present(myAlert, animated: true, completion: nil)
     }

滑动即可删除UITabelViewCell
