Ios 无法将数据从UIViewController传递到UIPageViewController和其他视图

我有一个segue指向一个PageViewControlr，它控制两个ViewControls，虽然我认为它设置正确并且可以顺利运行，但我无法将数据传递给其他两个视图。 我错过了什么？
无论如何，这是我从一个单元格指向一个PageViewController的序列：

   class HomeViewController:  UIViewController, UITableViewDelegate, UITableViewDataSource {
     if segue.identifier == "showDetails" {

            let localDetails = segue.destination as! localDetails

            let IndexPath = self.tableView.indexPathForSelectedRow!
            let row = IndexPath.row

        tableView.deselectRow(at: IndexPath, animated: true)

            localDetails.index = row
            let singleLocalInfo = restaurants[row]
            localDetails.localName = singleLocalInfo.locale }}

class PageViewController: UIPageViewController, UIPageViewControllerDelegate, UIPageViewControllerDataSource {

   func newVc(viewController: String) -> UIViewController {
         return UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: viewController)
     }

    lazy var orderedViewControllers: [UIViewController] = {
         return [self.newVc(viewController: "localDetails"),
                 self.newVc(viewController: "blueScreen")]
     }()  etc,etc... }

我的PageViewController：

   class HomeViewController:  UIViewController, UITableViewDelegate, UITableViewDataSource {
     if segue.identifier == "showDetails" {

            let localDetails = segue.destination as! localDetails

            let IndexPath = self.tableView.indexPathForSelectedRow!
            let row = IndexPath.row

        tableView.deselectRow(at: IndexPath, animated: true)

            localDetails.index = row
            let singleLocalInfo = restaurants[row]
            localDetails.localName = singleLocalInfo.locale }}

class PageViewController: UIPageViewController, UIPageViewControllerDelegate, UIPageViewControllerDataSource {

   func newVc(viewController: String) -> UIViewController {
         return UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: viewController)
     }

    lazy var orderedViewControllers: [UIViewController] = {
         return [self.newVc(viewController: "localDetails"),
                 self.newVc(viewController: "blueScreen")]
     }()  etc,etc... }

最后是需要显示数据的ViewControlr：

class localDetails: UIViewController {

  var localName: String = ""

  etc... 

}

我不得不删掉大部分代码，但你明白了。 谢谢

基本上

在实例化和分段到页面视图控制器的类中，在那里设置属性，然后在各自的控制器中设置属性

假设“showDetails”是页面视图控制器的序列标识符：

class HomeViewController:  UIViewController, UITableViewDelegate, UITableViewDataSource {

    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {

        if segue.identifier == "showDetails" {

            let pageVC = segue.destination as! PageViewController

            let IndexPath = self.tableView.indexPathForSelectedRow!
            let row = IndexPath.row

            tableView.deselectRow(at: IndexPath, animated: true)

            pageVC.index = row
            let singleLocalInfo = restaurants[row]
            pageVC.localName = singleLocalInfo.locale
            pageVC.blueValue = "the value for blueScreen"

        }

    }
}

class PageViewController: UIPageViewController, UIPageViewControllerDelegate, UIPageViewControllerDataSource {

    var index: Int = 0
    var localName: String = ""
    var blueValue: String = ""

    func newVc(viewController: String) -> UIViewController {
        return UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: viewController)
    }

    lazy var orderedViewControllers: [UIViewController] = {
        let v1 = self.newVc(viewController: "localDetails")
        v1.localName = self.localName
        let v2 = self.newVc(viewController: "blueScreen")
        v2.blueValue = self.blueValue
        return [v1, v2]
    }()

    //etc,etc...

}

检查委派和闭包以获取pas数据我做了，但据我所知，委派是用于返回数据的。

tableView.deselectRow（at:IndexPath，animated:true）

为什么调用此函数？哦，这只是为了获得所选行的索引号。嗨，DonMago，感谢您的帮助。一开始它不起作用，但当我添加“as！localDetails”时，它设法传递数据。：）谢谢
