iOS tableView的cell上添加控件，上拉出现控件复的解决方法

1、给控件添加tag值

- (void)Report:(LSXCommunityCell *)cell{
        self.dropView = [[PGGDropView alloc] initWithFrame:CGRectMake(200, 150 ,100, 200) withTitleArray:@[@"屏蔽此信息",@"举报该用户"]];
        [self.dropView beginAnimation];
        self.dropView.delegate = self;
        self.dropView.tag=100;
        [cell.contentView addSubview:self.dropView];    
}

2、在-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath方法中，添加
[[cell viewWithTag:100] removeFromSuperview];

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
    // 通过indexPath创建cell实例 每一个cell都是单独的
     LSXCommunityCell *cell=[tableView dequeueReusableCellWithIdentifier:_Identifier];
    [[cell viewWithTag:100] removeFromSuperview];
    
    if (cell == nil) {
        //重构Cell的时候，通过 _Identifier判断是否创建打电话按钮
        cell = [[LSXCommunityCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:_Identifier];
    }
    [[cell viewWithTag:100] removeFromSuperview];
    cell.selectionStyle=UITableViewCellSelectionStyleNone;
    cell.delegate=self;

    self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
    if(self.dataArray.count>0){
        _model =self.dataArray[indexPath.row];
        cell.Model=_model;
        __weak typeof(self) weakSelf = self;
        cell.ReportBlock = ^(LSXCommunityCell *cell) {
            [weakSelf Report:cell]; 
        };
        cell.CommunityIdBlock = ^(NSString *str) {
            _idStr =str;
        };
        cell.bjbrPhoneBlock = ^(NSString *str) {
            _bjbrPhoneStr=str;
        };
    }
    return  cell;
}
