如何在ios 10中处理后台推送通知？

Question

我不是在后台处理推送通知.

对于以下步骤中的处理推送通知: -

1. 在功能 - >启用远程通知.
2. 在功能 - >后台模式 - >启用远程通知.
3. 在didFinishLaunchingWithOptions中给出了ios 10的所有权限.
4. 用于推送通知UNUserNotificationCenter.

5. App In Foreground然后推送通知工作正常并且在方法调用之下:

   userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler
   

但我的问题是app在后台然后没有调用任何方法.所以任何人有想法或解决方案的背景为ios 10处理推送通知然后请帮助我.

谢谢.

Answer 1

当app在前台时调用willPresentNotification.看看他们的文档

 - (void)userNotificationCenter:(UNUserNotificationCenter *)center
       willPresentNotification:(UNNotification *)notification
         withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler {
    // The method will be called on the delegate only if the application is in the foreground.
    // If the method is not implemented or the handler is not called in a timely manner then the notification will not be presented.
    // The application can choose to have the notification presented as a sound, badge, alert and/or in the notification list.
    // This decision should be based on whether the information in the notification is otherwise visible to the user.

}

- (void)userNotificationCenter:(UNUserNotificationCenter *)center
didReceiveNotificationResponse:(UNNotificationResponse *)response
         withCompletionHandler:(void(^)())completionHandler {
    // The method will be called on the delegate when the user responded to the notification by opening the application,
    // dismissing the notification or choosing a UNNotificationAction.
    // The delegate must be set before the application returns from applicationDidFinishLaunching:.

}

尝试办理登机手续即可didReceiveNotificationResponse获得所需资料.

另外如果需要获取任何数据或任何处理,请在后台模式下启用后台获取并使用以下方法

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

    completionHandler(UIBackgroundFetchResultNewData);
}

根据应用程序状态处理APNS

   if(application.applicationState == UIApplicationStateInactive)
     {
        /* 
        # App is transitioning from background to foreground (user taps notification), do what you need when user taps here!
         */    
    }
    else if(application.applicationState == UIApplicationStateActive)
    {
        /*
         # App is currently active, can update badges count here
       */
    }
    else if(application.applicationState == UIApplicationStateBackground)
    {
        /* # App is in background, if content-available key of your notification is set to 1, poll to your backend to retrieve data and update your interface here */
    }
