ios - 接收器没有标识符为 'contact_segue' 的 segue

Question

我有一个问题，self.performSegueWithIdentifier("contact_segue", sender: self) 不工作并提示Receiver has no segue with identifier 'contact_segue'即使我有标识符。我使用 SWReveal 框架构建了与 TableView (类:slidingMenuController)一起使用的左侧滑动菜单。单击单元格后调用 MainNavigationController 的 changeView 函数来更改 View 。

import UIKit

class MainNavigationController: UINavigationController {

override func viewDidLoad() {
    super.viewDidLoad()


}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}
override func viewDidAppear(animated: Bool){
    super.viewDidAppear(false)
    self.performSegueWithIdentifier("Home", sender: self)
}


override func prepareForSegue(segue: UIStoryboardSegue!, sender: AnyObject!) {
    if segue.identifier == "Contact_se" {

    }
}
func changeView(){
       self.performSegueWithIdentifier("contact_segue", sender: self)      
    }
}

由tablecell中的左侧滑动菜单(类:slidingMenuController)调用的changeView:

 override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {

        let selectedItemMenu = arrayOfSlider[indexPath.row]

        let mainNav = MainNavigationController()

         mainNav.changeView()
    }

只需在您的 didSelectRowAtIndexPath 上添加此代码 self.performSegueWithIdentifier("contact_segue", sender: self) 吗？我相信这里不需要 MainNavigationController。
