Question

我正在尝试导航到特定的viewController。我在两个viewControllers中都有相同的tableView插座，一个是主VC，第二个是requestHistory VC。例如，如果用户在第一个viewController上并在tableview中选择单元格，它应该导航到特定的viewController，如果用户在第二个VC上并且选择了它应该重定向到另一个VC的相同单元格，则应该导航到第二个VC。请注意，我使用相同的表格视图单元格出口的VC和所需的结果是每个VC故事板应重定向到他们的特定目的地。我不确定我正面临的错误如下这是我目前的代码：

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    print("Row \(indexPath.row) selected")

    var currentStoryboard = UIStoryboard(name: "DoctorHomeViewController", bundle: nil)

    if currentStoryboard == "DoctorHomeViewController" {
    let storyboardd = UIStoryboard(name: "DoctorHome", bundle: Bundle.main)
    let eventViewController = storyboardd.instantiateViewController(withIdentifier: "EventDetailsNav") as? UIViewController
    self.navigationController?.pushViewController(eventViewController!, animated: true)
    }

    else{
        let storyboardd = UIStoryboard(name: "DoctorHome", bundle: Bundle.main)
        let eventViewController = storyboardd.instantiateViewController(withIdentifier: "RequestsHistory") as? UIViewController
        self.navigationController?.pushViewController(eventViewController!, animated: true)
    }
    }
}

任何帮助都会非常明显。

首先，您需要在身份检查器中为故事板中的相应视图控制器标记“使用故事板ID”，然后获取故事板ID并将其与您的View控制器进行比较。

 let currentStoryboard : String! = self.restorationIdentifier
    if currentStoryboard == "DoctorHomeViewController" {
        let storyboard = UIStoryboard(name: "DoctorHome", bundle: Bundle.main)
        let eventViewController = storyboard.instantiateViewController(withIdentifier: "EventDetailsNav") as! EventDetailsNav
        self.navigationController?.pushViewController(eventViewController!, animated: true)
    }

    else{
        let storyboard = UIStoryboard(name: "DoctorHome", bundle: Bundle.main)
        let eventViewController = storyboard.instantiateViewController(withIdentifier: "RequestsHistory") as RequestsHistory
        self.navigationController?.pushViewController(eventViewController!, animated: true)
    }

希望这会对你有所帮助。

如果当前viewController在tableView didSelect中导航，则为XCode swift 3
