DidReceiveLocalNotificationのアラートハンドラ/クロージャでVCからメソッドを追加する方法？

Question

みんな！

私のアプリがフォアグランドで、DidReceiveLocalNotificationがトリガーされたときに警告を表示したいとき。

AppDelegate.swiftの模擬ローカル通知にアラートを追加することはできますが、タイマー停止時にアニメーションを終了するには、ViewControllerからUIAlertActionクロージャ（コメント行参照）にメソッドを追加する方法がわかりません。

以下の私のコード：

func application(application: UIApplication, didReceiveLocalNotification notification: UILocalNotification) { 


    let alertTimerEnds = UIAlertController(title: "Timer finished!", message: nil, preferredStyle: .Alert) 

    let okAction = UIAlertAction(title: "OK", style: .Default) { finished in 

     print("You've pressed OK button") 

     //self.ViewController().finishAnimation() 

    } 

    alertTimerEnds.addAction(okAction) 
    self.window?.rootViewController?.presentViewController(alertTimerEnds, animated: true, completion: nil) 

} 

たぶん私はViewControllerをusind AppDelegateでそれを行う必要がありますか？

let someAppDelegate = UIApplication.sharedApplication().delegate as? AppDelegate 
    someAppDelegate?.application(UIApplication.sharedApplication(), didReceiveLocalNotification: UILocalNotification) { code for alert } 

Answer 1

あなたは

func application(application: UIApplication, didReceiveLocalNotification notification: UILocalNotification) 
{ 

    var viewController : UIViewController = (application.keyWindow?.rootViewController)! 

    while ((viewController.presentedViewController) != nil) { 

     viewController = viewController.presentedViewController! 
    } 

    let alert = UIAlertController(title: "", message: notification.alertBody, preferredStyle: UIAlertControllerStyle.Alert) 
    alert.addAction(UIAlertAction(title: "Ok", style: UIAlertActionStyle.Default, handler: {(action: UIAlertAction!) in})) 

    viewController.presentViewController(alert, animated: true, completion: nil) 

}) 

Show UIAlertController in didReceiveLocalNotification method

は、以下のコードで試してみてくださいことをやりたい場合は、これは現時点では存在しているのViewControllerにアラートが表示されます。

func application(application: UIApplication, didReceiveLocalNotification notification: UILocalNotification) { 

    var latestViewController : UIViewController! 
    let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate 

    if let viewControllers = appDelegate.window?.rootViewController?.presentedViewController { 

     latestViewController = viewControllers as UIViewController 

    } 
    else if let viewControllers = appDelegate.window?.rootViewController?.childViewControllers { 

     latestViewController = viewControllers.last! as UIViewController 

    } 

    //var alert: UIAlertView! 

    //alert = UIAlertView(title: "Title", message:"Message , delegate: nil, cancelButtonTitle:"Ok") 

    //alert.show() 

    let alert = UIAlertController(title: "Title", message:"Message", preferredStyle: .Alert) 
    let action = UIAlertAction(title: "OK", style: .Default) { _ in 
    // Put here any code that you would like to execute when 
    // the user taps that OK button (may be empty in your case if that's just 
    // an informative alert) 
    } 

    alert.addAction(action) 
    latestViewController.presentViewController(alert, animated: true){} 

} 

How do I migrate from UIAlertView (deprecated in iOS8)
