ios - 从 Table View controller 到 Tab Bar Controller

Question

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    if segue.identifier == "naarPersoonView"
    {
        let tabCtrl = segue.destination as! UITabBarController
        let vc = tabCtrl.viewControllers![0] as! PersoonViewController
        let indexPath = self.tableView.indexPathForSelectedRow
        vc.persoon = personen[(indexPath?.row)!]
    }
}

当我尝试将一个人从我的 TableViewController 发送到我的 persoonViewController(Tab view Controller)时，它给了我这个错误无法将类型“UIViewController”(0x10ff68758)的值转换为“DriesVD.PersoonViewController”(0x10e312750)。

Answer 1

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    if segue.identifier == "naarPersoonView"
    {
        let tabCtrl =  segue.destination as! UITabBarController
        let desView: PersoonViewController = tabCtrl.viewControllers?.first as! PersoonViewController
        let indexPath = self.tableView.indexPathForSelectedRow
        desView.persoon = personen[(indexPath?.row)!]
    }
}

我用上面的例子解决了我的问题，感谢您的快速回复
