点击应用程序图标时无法获得推送（远程）通知
Unable to get push (remote) notification when app icon tapped
根据 Local and Remote Notification Programming Guide，当发送远程通知并且您点击 SpringBoard 中的应用程序图标时：
The user taps the default button in the alert or taps (or clicks) the app icon. If the default action button is tapped (on a device running iOS), the system launches the app and the app calls its delegate’s application:didFinishLaunchingWithOptions: method, passing in the notification payload (for remote notifications) or the local-notification object (for local notifications).
If the notification is remote, the system also calls application:didReceiveRemoteNotification:fetchCompletionHandler:.
但是，当我看到远程通知标志并点击应用程序图标时，application:didFinishLaunchingWithOptions:（应用程序将在后台 运行）、application:didReceiveRemoteNotification: 和 application:didReceiveRemoteNotification:fetchCompletionHandler: 被称为...
我在点击横幅或警报时成功获取了推送通知的有效负载，我如何在点击应用程序图标时也能获取它？
谢谢
您需要继续阅读。您引用的部分的其余部分是 -
If the app icon is clicked on a computer running OS X, the app calls
the delegate’s applicationDidFinishLaunching: method in which the
delegate can obtain the remote-notification payload. If the app icon
is tapped on a device running iOS, the app calls the same method, but
furnishes no information about the notification.
注意我加粗的部分。简短的回答是，如果应用程序是从应用程序图标启动的，则不会提供有关可能已收到的任何通知的信息。
我 运行 遇到了同样的问题，不幸的是就像 Paulw11 所说的那样，您的应用程序将不会收到有关负载的任何信息。然而！我注意到徽章编号会反映错过的通知，因此在应用程序启动时，您可以检查您的 applicationBadgeNumber != 0 是否存在，如果不是，您可以查询服务器以获取发送的最后数据。
