UITableView does not load data

问题

I am relative new to iOS development. Right now, I created 2 ViewController using storyboard. The one consist one button that lead into another controller using segue (show).

This controller is TableViewController that embedded in Navigation Controller and already connected with its responsible class that inherit from UITableViewController.

My problem is this page doesn't load its data (NSMutableArray) that already initialized in viewDidLoad using

_dataClient = [NSMutableArray arrayWithObjects:@"First City",@"Second City",@"Third City",@"Forth City",@"Fift City", nil];

This is my table delegate and datasource:

#pragma mark - Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    return 0;
}

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

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    NSString *cellIdentifier = @"cellItem";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier forIndexPath:indexPath];

    // Configure the cell...
    if (!cell) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
    }

    cell.textLabel.text = [_dataClient objectAtIndex:indexPath.row];

    return cell;
}

Is there any step that I forgot to do?

You must return 1 section at least. Change this line:

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