//創建UIPageViewController
let pageViewController:UIPageViewController = UIPageViewController(transitionStyle: .scroll, navigationOrientation: .horizontal, options: nil);

pageViewController.setViewControllers([BBPlayWhatViewController() as UIViewController], direction: .forward, animated: false, completion: nil)
