iOS programmatic grouped table empty

Question

I have a programmatically implemented tableView, in the grouped style.

All I am getting is the gray pinstripes when it should be populated. So it is loading, but not ... something...

What more is necessary? If no more, then where else ought I look?

Also, how can I make the background color of the table the same as the cell's white color?

- (void)loadView {

    [super loadView];

    UITableView *view = [[UITableView alloc] initWithFrame:[UIScreen mainScreen].applicationFrame style:UITableViewStyleGrouped];

    [view setAutoresizingMask:UIViewAutoresizingFlexibleHeight|UIViewAutoresizingFlexibleWidth];

    self.view = view;

    [view reloadData];

}

Is viewDidLoad necessary?

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.
}

Thank you,

Morkrom

You have to provide your tableView with data.

For staters you'll need to define a dataSource. Its common to just use your viewController as the dataSource.

// in the .h find something similar and add <UITableViewDataSource>
@interface ViewController : UIViewController <UITableViewDataSource>

then when you make the tableView.

view.datasource = self;

Then you'll need to provide the data itself. Implement these methods:

#pragma mark - UITableView Datasource

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

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

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

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];

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

    [cell.textLabel setText:@"A Cell"];

    return cell;
}

Those methods will create 3 sections each with 3 rows. All the cells will just say A Cell. This is the basis for all tableViews. Just customize the data :)

So just for fun, what if the datasource is some other class? — Morkrom, Jan 30 '13 at 15:58
No problem. As long as that other class has the `` you just need to set your `view.datasource = THATCLASS` and it will work just fine. — Ryan Poolos, Jan 30 '13 at 16:19

You need to set dataSource and delegate properties for your table view so it will be able to pull data from them:

UITableView *view = ...
view.dataSource = self;
view.delegate = self;
