访问自定义推送通知负载

Question

我正在与Xcode 9.4.1 (9F2000)和一起工作Swift 3。

我将这些数据用于推送通知：

{
    "aps":{
        "alert":{
            "title":"Hello",
            "body":"How are you?"
            },
            "badge":0,
            "sound":"default",
            "my_value":"This is a test!"
    }
}

这是我的功能：

func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {

    let action = response.actionIdentifier
    let request = response.notification.request
    let content = request.content

    print("payload data: \(action)\(request)\(content)\n")

    completionHandler()
}

我认为自定义有效负载应该在request或 中content。但是在执行时print("payload data: \(action)\(request)\(content)\n")，它不会出现。

我究竟做错了什么？

你可以带着字典

let content = response.notification.request.content.userInfo
if let aps = content["aps"] as? [String: AnyObject] {
    let myValue = aps["my_value"]
    // DO STUFF, in myValue you will find your custom data
}
