Add object on a tableViewController

In the storyboard I have a static UItableViewController. I want to add a tableView on top of that tableVC. So I created a custom class that's a subclass of UITableViewController. Here's that code:

- (void)viewDidLoad {
    [super viewDidLoad];

    self.tableView.bounds = self.textField.bounds;
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

// -----------------------------------------------------------------------------
#pragma mark - TableView delegate
// -----------------------------------------------------------------------------
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    return 1;
}

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

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *cellID = @"cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellID];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellID];
    }

    [cell.textLabel setText:self.resultArray [indexPath.row]];

    return cell;
}

Then in the main viewControllers class I did the following:

resultTableVC *tableView = [[resultTableVC alloc] initWithStyle:UITableViewStylePlain];
tableView.textField = self.tagsTextField;

[self.view addSubview:tableView.tableView];

When I run the app, I get the following error message:

Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<mainTableViewController 0x7fe35a550530> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key tagResultView.'

I don't know what the error means, or how to fix it. (If this isn't correct) What's the proper way to add a tableView on top of an existing tableViewController?

You are getting the error because there is no property called tagResultView. There is bad link to a mainTableViewController object that probably is specifying tagResultView. Check your storyboard/xib and remove any link to the undefined key specified(tagResultView). This happens when you remove something from the view controller improperly or when you rename views.

For creating an autocomplete UITextField I don't think you need to add a UITableView to another UITableView, Why not trying to have UIView or CustomTextField that will contain a UITextField and a UITableView for the autocomplete stuff then with the UITextFieldDelegate protocol you can present the UITableView anywhere you want it using Autolayout. Then just create a UITableViewCell and add the CustomTextField to it.
