最近有个同事问我，他工程运行时就会有如下提示，但是不影响功能：You've implemented -[<UIApplicationDelegate> application:didReceiveRemoteNotification:fetchCompletionHandler:], but you still need to add "remote-notification" to the list of your supported UIBackgroundModes in your Info.plist.
该如何解决，如下：
capablilties->background modes->remote notifications
