应用程序：didReceiveRemoteNotification：fetchCompletionHandler：未调用iOS 9 [重复]

Question

我想在应用程序中保存一些推送通知数据。但是如果用户通过在多任务查看器上向上滑动应用程序来终止应用程序（暂停或未运行状态），我无法保存数据。我使用了 application:didReceiveRemoteNotification:fetchCompletionHandler ：处理它。但我仍然无法保存推送通知数据

我已经设置了这样的应用设置

和有效载荷，

 {
    "aps" : {
       "alert" = "Notification with custom payload",
    },
   "content-available" = 1
 }

而 application:didReceiveRemoteNotification:fetchCompletionHandler: 看起来像这样

- (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");

        NSString *info = [[userInfo valueForKey:@"aps"]valueForKey:@"alert"];

        completionHandler(UIBackgroundFetchResultNewData);

    } else {

        NSLog(@"Active");

        //Show an in-app banner

        completionHandler(UIBackgroundFetchResultNewData);

    }
}

这是完全正常的。如果您检查设备的控制台日志，您将看到来自系统的消息，指出它不会唤醒应用程序，因为它已被用户终止。
