ios - 将数据从 TableView Controller 传递到 View Controller

Question

我在从 TableView Controller 移动到 View Controller 以显示有关所选特定单元格的信息时遇到问题。

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    if segue.identifier == "SentDetailView" {
        let indexPath: NSIndexPath = self.tableView.indexPathForSelectedRow! as NSIndexPath
        let referrals = referralsSent[indexPath.row]

        let destViewController = segue.destination as! SentDetailViewController
        destViewController.referringTo = referrals.referTo
        destViewController.patientsName = referrals.patientsName
        //print("Contained value during segue " + destViewController.patientsName!)
        destViewController.patientsPhoneNumber = referrals.patientsNumber
        destViewController.patientsEmail = referrals.patientsEmail
        destViewController.comments = referrals.comment
    }
}

Storyboard设置:

我得到以下结果:

我选择一个单元格，它只是突出显示，不执行任何操作。

Answer 1

您应该覆盖didSelectRowAt并调用performSegue，并将sender作为选定的索引路径。试试这个。

override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    self.performSegue(withIdentifier: "SentDetailView", sender: indexPath)        
}

还有这个。

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    if segue.identifier == "SentDetailView"{
        let indexPath = sender as! IndexPath
        let referrals = referralsSent[indexPath.row]

        let destViewController = segue.destination as! SentDetailViewController
        destViewController.referringTo = referrals.referTo
        destViewController.patientsName = referrals.patientsName
        //print("Contained value during segue " + destViewController.patientsName!)
        destViewController.patientsPhoneNumber = referrals.patientsNumber
        destViewController.patientsEmail = referrals.patientsEmail
        destViewController.comments = referrals.comment
    }
}
