ios - PageViewController 不工作

Question

我正在集成 PageViewController。我遇到错误。

Could not cast value of type 'UIViewController' (0x105390ca8) to 'VeggieIndia.PageContentViewController' (0x10273bc98).

override func viewDidLoad() {
    super.viewDidLoad()

    arrPagePhoto = ["background", "background", "3.jpg"];

    self.setViewControllers([getViewControllerAtIndex(index: 0)], direction: .forward, animated: true) { (true) in

    }

    self.dataSource = self

    //  self.setViewControllers([getViewControllerAtIndex[0]] as [UIViewController], direction: UIPageViewControllerNavigationDirection.Forward, animated: false, completion: nil)

    // Do any additional setup after loading the view, typically from a nib.
}

func getViewControllerAtIndex(index: NSInteger) -> PageContentViewController {
    // Create a new view controller and pass suitable data.
    let pageContentViewController = self.storyboard?.instantiateViewController(withIdentifier: "PageContentViewController") as! PageContentViewController
    pageContentViewController.strPhotoName = "\(arrPagePhoto[index])"

    pageContentViewController.pageIndex = index
    return pageContentViewController
}

问题出在模块中，如果您在身份检查器中查看类名，您会发现模块是 None ，关注类并单击 enter 或选中 Inherit Module From Target
