以编程方式填充的UITableView无法填满屏幕

Question

I am following this tutorial: http://www.appcoda.com/ios-programming-tutorial-create-a-simple-table-view-app/ which shows how to create an UITableView and populate it programmatically. All's good, it works.

Now, I am trying to make the table fill the screen: regardless of the device or orientation. I did this:

But now the table view simply does not appear in my screen (I imagine it is somewhere far away due to a problem with the constraints?).

There really isn't much code for me to show. I literally just placed an UITableView into the interface builder, and followed that tutorial to set the delegate to my view controller. The methods would be

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return [tableData count];
}

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

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];

    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
    }

    cell.textLabel.text = [tableData objectAtIndex:indexPath.row];
    return cell;
}

Where tableData is an array with 16 strings.

Try to remove all constraints, then select your tableView and add their again and press Add 4 constraints . Be sure, you don't have some ambiguity.
