多个ios推送通知导致应用程序崩溃。由于信号6（SIGABRT）而终止

Question

当我从收到的通知启动我的应用程序，应用程序午餐成功并进入受人尊敬的窗口，现在再次当我收到通知，而应用程序是打开然后应用程序崩溃，意味着每当我的应用程序不在后台或前台运行，我启动我的应用程序使用通知...然后再次当我收到通知应用程序崩溃

我的代码在下面，请帮忙

只需删除一行代码就可以完美地工作，我在didFinishLaunchingWithOptions方法中添加了观察者。我更正的代码如下：，

Func应用程序（应用程序：UIApplication，didFinishLaunchingBackOptions启动选项：[NSObject： AnyObject]？）-

let barAppearace = UIBarButtonItem.appearance()
barAppearace.setBackButtonTitlePositionAdjustment(UIOffsetMake(0, -60), forBarMetrics:UIBarMetrics.Default)  //CODE TO REMOVETITLE OFACK BUTTON ITEM IN NAVIGATIION CONTROLLER


let notificationTypes : UIUserNotificationType = [.Alert, .Badge, .Sound]
let notificationSettings : UIUserNotificationSettings = UIUserNotificationSettings(forTypes: notificationTypes, categories: nil)
UIApplication.sharedApplication().registerUserNotificationSettings(notificationSettings)




if let notification = launchOptions?[UIApplicationLaunchOptionsRemoteNotificationKey] as? [String: AnyObject] {

//从这里删除了这个观察者，并将其放置在所需的视图控制器i.e.the位置

     NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(AgentAllTab.readyNotificationAction), name: "AgentReadyNotification", object: nil)

//还可以在放置此观察者的位置添加Denit，并从viewcontroller中删除该观察者，以便在应用程序终止时从通知中心删除该观察者

让userInfo=launchOptions！[UIApplicationLaunchActionsRemoteNotificationKey]作为？[字符串：AnyObject]

    let aps = userInfo!["aps"] as! [String: AnyObject]
    print("Remote noti data from didFinishLaunchingWithOptions \(aps)")

    let data = aps["data"]  as! [String: AnyObject]
    let type = aps["type"] as! Int
    print("notification TYPE  \(type)")

开关类型{案例0:

        NSUserDefaults.standardUserDefaults().setObject(aps, forKey: "notificationlauch")

    break
   default:
   break

}

返回真实

}
