Answer 1

Did you make SASlideMenuViewController as datasource of the UITableView ?

Check the code :

- (void)viewDidLoad
{
    [super viewDidLoad];

    self.tableView.dataSource = self;
}

or connecting File's owner as a datasource of your table view in Xib.

Answer 2

I think you just set UITableView.dataSource but not UITableView.delegate . Set it in your xib. and you should implement the method below:

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

and it must return a positive number.
