Answer 1

您是否将SASlideMenuViewController作为UITableView的数据源？

检查代码：

- (void)viewDidLoad
{
    [super viewDidLoad];

    self.tableView.dataSource = self;
}

或将File的所有者连接为Xib中表视图的数据源。

Answer 2

我认为您只需设置UITableView.dataSource而不是UITableView.delegate。将它设置在你的xib中。你应该实现以下方法：

 - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath;

并且必须返回正数。
