Question

这些是应用崩溃之前和之后的图像，控制台只显示消息来自调试器的消息：由于信号6终止 [[ 我的应用程序通过推送通知成功启动（未运行时），并且我获得了所需的屏幕和结果，但在应用程序处于活动状态时再次通过通知时会再次收到通知时崩溃。当应用程序正常启动从主屏幕通知功能和行动工作正常应用程序活动和后台。我发布我的代码下面请帮助我。

当我从收到的通知中启动我的应用程序时，应用程序成功午餐并转到受尊重的窗口，现在再次当应用程序打开时我收到通知然后应用程序崩溃，意味着每当我的应用程序未在后台或前台运行时我使用通知启动我的应用..然后当我收到通知应用程序崩溃时再次

我的代码如下，请帮助

导入UIKit

只需删除一行代码就可以完美地运行，我在didFinishLaunchingWithOptions方法中添加了观察者。我更正后的代码如下，

func application（application：UIApplication，didFinishLaunchingWithOptions launchOptions：[NSObject：AnyObject]？） - ＆gt;布尔{ //在应用程序启动后覆盖自定义点。

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] {

//从此处移除此观察者并将其放置在需要它的位置即所需的视图控制器

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

//还在放置此观察者的位置添加deinit，并从viewcontroller中删除观察者，以便在终止app时将观察者从通知中心移除

让userInfo = launchOptions！[UIApplicationLaunchOptionsRemoteNotificationKey]为？ [String：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)")

切换类型{案例0：

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

    break
   default:
   break

}

返回true

}

//剩下的事情保持不变，谢谢@David V

多个ios推送通知会导致应用程序崩溃。由于信号6（SIGABRT）而终止
