ios - PageViewController不起作用

我正在积分PageViewController。我有个错误。
无法将“UIViewController”（0x105390ca8）类型的值强制转换为“veggieinda.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
}

最佳答案

问题是在模块中如果您在identity inspector中查看类名，就会发现module is None，关注类并单击enter或checkInherit Module From Target
