如何从推送通知响应Swift 3 / iOS获取数据

https://github.com/edamov/pushok

我得到了推送通知,但我不知道如何在Swift 3中提取响应.

这就是我所拥有的.

// Push notification received
    func application(_ application: UIApplication, didReceiveRemoteNotification data: [AnyHashable : Any]) {
        // Print notification payload data
        print("Push notification received: \(data)")

        let aps = data[AnyHashable("aps")]!

        print(aps)
    }

我可以创建推送通知和控制台消息工作但打印出来…

Push notification received: [AnyHashable("samplekey"): samplevalue, AnyHashable("aps"): {
    alert =     {
        body = hey;
        title = "Hello!";
    };
    sound = default;
}]
{
    alert =     {
        body = hey;
        title = "Hello!";
    };
    sound = default;
}

所以我的问题是如何访问’body’和’title’的alert中的数据？

我尝试访问变量,但我不断收到错误,因为我不确定我应该如何访问它,并且在任何教程中找不到关于此主题的任何文档.

guard
    let aps = data[AnyHashable("aps")] as? NSDictionary,
    let alert = aps["alert"] as? NSDictionary,
    let body = alert["body"] as? String,
    let title = alert["title"] as? String
    else {
        // handle any error here
        return
    }

print("Title: \(title) \nBody:\(body)")
