Question

I created a UITableView programmatically, but none of its methods were called. I must have missed something:

- (void)viewDidLoad
{
    [super viewDidLoad];
    ...     
    self.transactionView = [[UITableView alloc] initWithFrame:CGRectMake(0.0, CARD_VIEW_Y, 320.0, CARD_VIEW_H)];
    self.transactionView.delegate = self;
    [self.view addSubview:self.transactionView];

Answer 1

You need to wire both the delegate AND the dataSource of the tableview. UITableViewDataSource provides the methods to fill the actual table with data.
