Question

标题解释了发生了什么。应用程序正在运行但最小化。通知将显示给用户。当用户点击通知时，应用程序将进入前台并输入方法didReceiveRemoteNotification。但是，如果用户单击应用程序图标而不是恢复应用程序，则不会执行didReceiveRemoteNotification方法。

这是我的代码：

在didFinishLaunchingWithOptions中：

 //FOR ALLOWING NOTIFICATIONS
            let notificationSettings = UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)
            UIApplication.sharedApplication().registerUserNotificationSettings(notificationSettings)
            UIApplication.sharedApplication().registerForRemoteNotifications()

 func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
        let deviceTokenStr = convertDeviceTokenToString(deviceToken)
        GlobalVariables.UserDefaults.setValue(deviceTokenStr,forKey: "Push_Notification_Reg_ID");
        RZLog.VIP("The PushNotification Device Token is: \(deviceTokenStr)")

    }

    func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) {

        RZLog.Error(error.description)
    }

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject], fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {
        RZLog.Debug("A NEW NOTIFICATION HAS BEEN RECEIVED")
        //handle

                completionHandler(UIBackgroundFetchResult.NoData)
        }
    }

Answer 1

这是设计的。在应用程序中收到远程通知时（在后台或前台）以及用户从通知中启动应用程序时，将调用此方法。

如果用户点按应用图标，则仅

applicationWillEnterForeground:

和

applicationDidBecomeActive:

将被称为

背景中的

将不会调用didReceiveRemoteNotification。你应该使用

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {

    if(application.applicationState == UIApplicationStateInactive) {

    NSLog(@"Inactive");

    //Show the view with the content of the push

    completionHandler(UIBackgroundFetchResultNewData);

} else if (application.applicationState == UIApplicationStateBackground) {

    NSLog(@"Background");

    //Refresh the local model

    completionHandler(UIBackgroundFetchResultNewData);

} else {

    NSLog(@"Active");

    //Show an in-app banner

    completionHandler(UIBackgroundFetchResultNewData);

}
}

基本上，didReceiveRemoteNotification仅在以下场景中调用：

点按推送通知横幅＆amp; app进入前台并调用didReceiveRemoteNotification。
当App在前台运行时，推送通知到达＆amp;调用didReceiveRemoteNotification。

来自Apple文档：如果在推送通知到达时应用程序未运行，则该方法将启动应用程序并在启动选项字典中提供相应的信息。该应用程序不会调用此方法来处理该推送通知。相反，您的应用程序的实现：willFinishLaunchingWithOptions：或application：didFinishLaunchingWithOptions：方法需要获取推送通知有效负载数据并做出适当的响应。

除非应用程序从通知中恢复，否则不会调用didReceiveRemoteNotification
