Creating a Table View Programmatically

If you choose not use UITableViewController for table view management, you must replicate what this class gives you "for free".

Adopt the Data Source and Delegate Protocols

@interface RootViewController : UIViewController <UITableViewDelegate, UITableViewDataSource>

@property (nonatomic, strong) NSArray *timeZoneNames;
@end

Create and Configure a Table View

第二步就是 allocate and initialize an instance of the UITableView class.

- (void)loadView
{
    UITableView *tableView = [[UITableView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame] style:UITableViewStylePlain];
    tableView.autoresizingMask = UIViewAutoresizingFlexibleHeight|UIViewAutoresizingFlexibleWidth;
    tableView.delegate = self;
    tableView.dataSource = self;
    [tableView reloadData];

    self.view = tableView;
}
