Swift didReceiveRemoteNotification方法

Question

我遇到警告问题：

此方法来自官方文档，因此我不了解它（或实现）的错误

Answer 1

试试这段代码：

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject], fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {
        if application.applicationState == .Inactive || application.applicationState == .Background {
            self.sendGoogleAnalyticsEventWithInfo(userInfo)
        }
    }
