in app implemented push notification. when app in running state , if push notification come handle code.

func application(application: uiapplication, didreceiveremotenotification userinfo: [nsobject : anyobject]) {               print(userinfo)      myid = (userinfo["id"] as? string)!     print(myid)     if let notification = userinfo["aps"] as? nsdictionary,         let alert = notification["alert"] as? string {             var alertctrl = uialertcontroller(title: "notification", message: alert string, preferredstyle: uialertcontrollerstyle.alert)             alertctrl.addaction(uialertaction(title: "ok", style: uialertactionstyle.default, handler: nil))             // find presented vc...             var presentedvc = self.window?.rootviewcontroller             while (presentedvc!.presentedviewcontroller != nil)  {                 presentedvc = presentedvc!.presentedviewcontroller             }             presentedvc!.presentviewcontroller(alertctrl, animated: true, completion: nil)        } 

what want :: when app not running , if push notification come want open perticular post based on notification post id. how can this? here code

func application(application: uiapplication, didfinishlaunchingwithoptions launchoptions: [nsobject: anyobject]?) -> bool {     svprogresshud.setdefaultmasktype(svprogresshudmasktype.black)     uiapplication.sharedapplication().applicationiconbadgenumber = 0     let dictemp = launchoptions?["uiapplicationlaunchoptionsremotenotificationkey"]     if dictemp != nil{           window = uiwindow(frame: uiscreen.mainscreen().bounds)         storyboard = uistoryboard(name: "main", bundle: nil)          myid = (dictemp["id"] as? string)!           let controller:pushnotificationpostviewcontroller = self.storyboard.instantiateviewcontrollerwithidentifier("pushnotificationpostviewcontroller") as! pushnotificationpostviewcontroller         navigation = uinavigationcontroller(rootviewcontroller: controller)         window?.rootviewcontroller = navigation         window?.makekeyandvisible()      }      else     {         window = uiwindow(frame: uiscreen.mainscreen().bounds)         storyboard = uistoryboard(name: "main", bundle: nil)         let controller:mainviewcontroller = self.storyboard.instantiateviewcontrollerwithidentifier("mainviewcontroller") as! mainviewcontroller         navigation = uinavigationcontroller(rootviewcontroller: controller)         window?.rootviewcontroller = navigation         window?.makekeyandvisible()     }       //print(nsuserdefaults.standarduserdefaults().valueforkey("pushnotify")as! bool)      let notificationtypes: uiusernotificationtype = [uiusernotificationtype.alert, uiusernotificationtype.badge, uiusernotificationtype.sound]     let pushnotificationsettings = uiusernotificationsettings(fortypes: notificationtypes, categories: nil)     application.registerusernotificationsettings(pushnotificationsettings)      if (nsuserdefaults.standarduserdefaults().valueforkey("pushnotify")) != nil    {         pushnotification = nsuserdefaults.standarduserdefaults().valueforkey("pushnotify") as! bool        // let notificationcheck = nsuserdefaults.standarduserdefaults().valueforkey("pushnotify") as! bool          if (pushnotification == true)         {             application.registerforremotenotifications()         }         else         {             application.unregisterforremotenotifications()         }     }   else    {         application.registerforremotenotifications()     }       return true } 

but code not getting id means myid getting nil. how can this?

i think when quit application didreceiveremotenotification method not gets called when tap on notification, instead method didfinishlaunchingwithoptions gets called there have check weather application launched notification

put below code in didfinishlaunchingwithoptions :

var notification: uilocalnotification = (launchoptions[uiapplicationlaunchoptionsremotenotificationkey] as! uilocalnotification) if notification != nil { // handle notification } 

above code handling push notifications if using local notification try:

// if launched local notification var notification: uilocalnotification = (launchoptions[uiapplicationlaunchoptionslocalnotificationkey] as! uilocalnotification) if notification != nil {  }
