Ios 行给出了奇怪的值

我有一个定制的手机。在

cellforrowatinexpath

方法中，我将

indexPath.row

编号显示为自定义

UILabel

，也在

cellforrowatinexpath

中定义。该标签将作为该自定义单元格的子视图添加。当我有很多单元格并向下滑动tableview时，那

indexath.row

数字有奇怪的值，如果我滚动更多，值就会变大。我怎么能绕过这个

[编辑]我的代码：

    self.sksTableViewCell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    self.sksTableViewCell.textLabel.text = [NSString stringWithFormat:@"  %@",[[[ArraySingleton sharedManager].sharedArray objectAtIndex:indexPath.row] name]];
    self.sksTableViewCell.backgroundColor = [UIColor clearColor];

    if ([[[[ArraySingleton sharedManager].sharedArray objectAtIndex:indexPath.row] times] count]) {
        self.sksTableViewCell.expandable = YES;

避免在cellForRow方法中创建新的UIButton和UILabel。UITableView中的单元格被重用，因此当您滚动时从屏幕上消失的对象将再次用于显示新行。每次发生这种情况时，您都会添加一个新视图

相反，您应该只创建一次所有视图层次结构，并更新需要更新的视图

if (!cell) {
    cell = [[SKSTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
    //create all your subviews here
}

//update subviews here

---

不要为每个单元创建新的UI组件对象，只需在单元重用后再创建一次即可

你能给我们看一下你的代码吗？也许每次调用

cellForRow

时你都在添加一个新标签？如果是这样，您不应该这样做。为什么要使用属性保留对最后一个单元格的引用？
