ios - 接收器没有标识符 swift 2 的 segue

Question

我正在尝试通过 segue 将值从 Realm 传递到另一个 View Controller 。问题是它因错误而崩溃:Reciever has no segue with identifier。我尝试了其他方式，prepareforsegue，但效果不如这个。

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
    let lektire = datasource[indexPath.row]
    let destinationVC = DetaljiViewController()
    destinationVC.programVar = lektire.ime
    destinationVC.performSegueWithIdentifier("oLektiri", sender: self)
}

但是，我的 segue 确实存在，并且它的标识符设置正确(见下面的屏幕截图)。

这是怎么回事，我该如何解决这个问题？

我相信这就是您要查找的内容，您必须从当前所在的 View Controller 调用 performSegueWithIdentifier 并将发送者设置为 indexPath，或者您可以将其设置为数据源项。

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
   self.performSegueWithIdentifier("oLektiri", sender: indexPath)

   // Another WAY
   self.performSegueWithIdentifier("oLektiri", sender: datasource[indexPath.row])
}

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    if(segue.identifier == "oLektiri") {
       let indexPath = sender as! NSIndexPath
       let toViewController = segue.destinationViewController as? NextViewController
       let lektire = datasource[indexPath.row]
       toViewController?.selectedObject = lektire
    }

    // Another WAY
    if(segue.identifier == "oLektiri") {
       let lektire = sender as? lektireTYPE
       let toViewController = segue.destinationViewController as? NextViewController
       toViewController?.selectedObject = lektire
    }
}

// An example of what the next view controller should look like
class NextViewController: UIViewController {
    var selectedObject: ObjectType?
}
