从Table View控制器到Tab Bar控制器的Segue

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TableViewController发送到我的persoonViewController（Tab view Controller）时，它给了我这个错误Could not cast value of type 'UIViewController' (0x10ff68758) to '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)!]
    }
}

我用上面的示例解决了我的问题，感谢您的所有快速回复
