  • ios 实现在tableViewCell上面添加长按手势 删除该条cell以及列表后台数据等

    自己的代码  需要   把属性更改成自己要使用的

    //创建长按手势

        在cellForRowAtIndexPath代理方法中

                    UILongPressGestureRecognizer *longPressGR = [[UILongPressGestureRecognizer alloc]initWithTarget:self action:@selector(lpGR:)];

                    //设定最小的长按时间 按不够这个时间不响应手势

                    longPressGR.minimumPressDuration = 1;

                    [cell addGestureRecognizer:longPressGR];

    //实现手势对应的功能

    -(void)lpGR:(UILongPressGestureRecognizer *)lpGR

    {

        if (lpGR.state == UIGestureRecognizerStateBegan) {//手势开始

            CGPoint point = [lpGR locationInView:self.tbFirst];

            self.index = [self.tbFirst indexPathForRowAtPoint:point]; // 可以获取我们在哪个cell上长按

            self.indexNum = self.index.row;

        }

        if (lpGR.state == UIGestureRecognizerStateEnded)//手势结束

        {

            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"是否删除" message:nil delegate:self cancelButtonTitle:@"确认" otherButtonTitles:@"取消", nil];

            [alert show];

        }

    }

     //提示框代理方法

    - (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{

        if (buttonIndex == 0) {

            NSDictionary * dic = self.hopeDs[self.indexNum];

            NSString *url = [NSString stringWithFormat:@"%@%@",JJBaseUrl,@"/v1/infomarket/delPost"];

            NSMutableDictionary *params = [NSMutableDictionary dictionary];

            params[@"postId"] = dic[@"id"];

            params[@"ticket"] = [JJUserInfoModel userInfoFromFile].ticket;

            [JJHttpTools deleteUrl:url params:params success:^(id json) {

                [JJMBProgressTool showSuccessProgressViewWithText:@"已删除"];

                [self.hopeDs removeObjectAtIndex:self.indexNum];

                //删除列表内容

                [self.tbFirst deleteRowsAtIndexPaths:[NSArray arrayWithObject:self.index] withRowAnimation:UITableViewRowAnimationFade];

            } failure:^(NSError *error) {

                

            }];

        }else{
