發送到實例Swift 2.1的無法識別的選擇器

下面的代碼在每次保存任務時都會導致崩潰。新數據需要輸入到Detail View控制器並保存。這可以工作，但應用程序每次都會終止。請告訴我這是爲什麼不工作：發送到實例Swift 2.1的無法識別的選擇器

代碼：

var detailViewController: DetailViewController? = nil 
var managedObjectContext: NSManagedObjectContext? = nil 


override func viewDidLoad() { 
    super.viewDidLoad() 
    // Do any additional setup after loading the view, typically from a nib. 
    self.navigationItem.leftBarButtonItem = self.editButtonItem() 

    let addButton = UIBarButtonItem(barButtonSystemItem: .Add, target: self, action: "addNewCourseWork") 
    self.navigationItem.rightBarButtonItem = addButton 
    if let split = self.splitViewController { 
     let controllers = split.viewControllers 
     self.detailViewController = (controllers[controllers.count-1] as! UINavigationController).topViewController as? DetailViewController 
    } 

    //hide blank cells 
    let backgroundView = UIView(frame: CGRectZero) 
    tableView.tableFooterView = backgroundView 

    // register for receiving notification, I need to update detail view from this exact same class, not just any MasterView class instance... 
    NSNotificationCenter.defaultCenter().addObserver(self, selector:"MasterViewController.pushNewValuesToDetail", name: "updateDetailTableValues", object: nil) 
} 

func pushNewValuesToDetail() { 
    self.performSegueWithIdentifier("showDetail", sender: nil) 
}

錯誤：

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '- MasterViewController.pushNewValuesToDetail]: unrecognized selector sent to instance 0x7fc622d1b820

隨意標記您的問題解決，如果它已解決。 – Putz1103

嘗試

NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(pushNewValuesToDetail), name: "updateDetailTableValues", object: nil)

你並不需要注意的基類，並且創建選擇器的新方法（在最新版本的Xcode中）是#selector。
