Question

I am trying to call reloadData on my UITableView. I am making my app without interface builder.

This code would works with Interface Builder, but does not seem to without.

When I compare my code to what I used to do in interface builder, I am missing the bit in code where I would drag the View Controller to the UITableView. I have the delegates and datasource set and working. Is there something I am missing in my code?

EDIT:
This is set up in my viewDidLoad
The _tableView has the property set and is Synthesized.

//Data is set into an NSArray then copied into an NSMutableArray
_nsarray = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:docPath error:NULL];

_nsmArray = [[NSMutableArray alloc] init];
[_nsmArray addObjectsFromArray:_nsarray];

_tableView = [[UITableView alloc] initWithFrame:CGRectMake(0, 0, 320, 416)];
_tableView.delegate = self;
_tableView.dataSource = self;
[self.view addSubview:_tableView];


-(void)refreshTable {
    //_tableView = [[UITableView alloc] initWithFrame:CGRectZero];
    [self.tableView reloadData];
}

How are you managing your table data? NSArray?

You need to provide these details as what you have posted should work: setting the dataSource and delegate and calling reloadData. When you simply “reloadData” you need to ensure there were changes to the dataSource. If no changes were made to the dataSource (i.e. add / remove an object from the array), then nothing is going to happen.
