Question

I am having issues with what I can only imagine is a very simple problem. I am loading a UITableViewController class called LocationViewController from one UIViewController:

LocationViewController *lvc = [[LocationViewController alloc] init];
[self.navigationController pushViewController:lvc animated:true];

In this class I have the 3 following method implemented:

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return 3;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"CityCell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    cell.textLabel.text = @"Test";
    return cell;
}

And I am getting the following error:

UITableView dataSource must return a cell from tableView:cellForRowAtIndexPath:'

I have had this error before when transitioning between ViewControllers using the StoryBoard this was because the CellIdentifier was not correct. I have no idea what I am doing wrong. I have tried loading a nib file with this ViewController but that throws the same error.

You have to allocate the cell. use this code.

static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
   if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
