在我向下滚动 UITableView 之前，我遇到了 UITableView 无法点击的类似问题 - 我注意到，在我添加 NSNotification 以在下载管理器中下载所有图像后更新表格。我正在使用 [_tableview reloadData] 更新我的表格视图；

我意识到我犯了一个非常简单的错误——reloadData 并没有真正在主线程上调用。一旦我做到了

[self.tableView performSelectorOnMainThread:@selector(reloadData) withObject:nil waitUntilDone:NO];

代替

[_categoryTableView reloadData];

UITableView 卡住的问题消失了。

我不确定这是否正是@Rue Vitale 的问题，但如果我在寻找问题的根源时遇到了这个话题，我认为值得分享。

我不知道你在哪里创建按钮，但你应该做这样的事情：

- (UITableViewCell*) tableView: (UITableView*) tableView cellForRowAtIndexPath: (NSIndexPath*) indexPath
{
    static NSString* cellIdentifier = @"buttonsCell";

    UITableViewCell* cell = [tableView dequeueReusableCellWithIdentifier: cellIdentifier];

    if (cell == nil)
    {
        cell = [[UITableViewCell alloc] initWithStyle: UITableViewCellStyleSubtitle
                                      reuseIdentifier: cellIdentifier];

your code...        

    }

    return cell;
}
