swift - 应用程序运行时 didReceiveRemoteNotification 未运行(前台)

Question

我有一个奇怪的案例。我的 swift ios 应用程序已连接到 Cloudkit。如果应用程序未运行(后台状态)，我每次都会收到通知徽章和警报!如果应用程序正在运行，则不会收到任何通知!我知道它没有击中 Remote ，因为我这样做:1.在didReceiveRemoteNotification事件中添加断点2. 在插入的 iPhone 中运行 xcode3. NSLog("检测到didReceiveRemoteNotification")，所以最终代码如下

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]){
  NSLog("detected didReceiveRemoteNotification")
}

我知道错误不是来自 cloudkit 或 APNS，因为当手机处于后台状态时，我确实收到了警报横幅和徽章。

你能指导我为前台状态正确设置它吗!？

我运行的是 ios v9.3

更新#1我认为文档的措辞很差。它清楚地表明两者都在前台运行，这是我关心的；尽管如此，修复比文档更准确!

Unlike the application:didReceiveRemoteNotification: method, which is called only when your app is running in the foreground, the system calls this method when your app is running in the foreground or background.

您实现了错误的方法。实现:

func application(_ application: UIApplication,
    didReceiveRemoteNotification userInfo: [NSObject : AnyObject],
    fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void)

正如文档所解释的:

Unlike the application:didReceiveRemoteNotification: method, ... the system calls this method when your app is running in the foreground or background.
