Select 显示推送通知的参数

Question

我收到如下所示的推送通知：

{
    "aps" : {
        "alert" : {
            "loc-key" : "localized_pn_text",
            "loc-args" : [ "France", "Frank"]
        },
        "sound" : "chime.aiff"
    },
    "acme" : "foo"
}

在我的 Localizable.strings 中，我现在可以添加一个带有关键字 "localized_pn_text" 的字符串来本地化推送通知。

有没有办法订购或select特定参数。例如，我可以将 "Frank, you got a push notification" 显示为 localised 文本吗？

Answer 1

您可以简单地在 dictionary 中添加自定义键，例如

{
    "aps" : {
        "alert" : {
            "loc-key" : "localized_pn_text",
            "loc-args" : [ "France", "Frank"]
        },
        "sound" : "chime.aiff"
    },
    "acme" : "foo",
    "customText": "Frank, you got a push notification"
}

使用

读取customText的值

if let customText = notification.request.content.userInfo["customText"] as? String {
    print(customText)
}

Answer 2

您有两个选择：

在您的 Localizable.strings 中添加 "localized_pn_text" = "%@, you got a push notification"，然后只发送 "Frank" 作为 "loc-args" ("loc-args" : [ "Frank"])
实现一个Notification Service Extension来拦截推送通知并以编程方式创建其内容，下面是一个示例：

class NotificationService: UNNotificationServiceExtension {

    var contentHandler: ((UNNotificationContent) -> Void)?
    var bestAttemptContent: UNMutableNotificationContent?

    override func didReceive(_ request: UNNotificationRequest, withContentHandler contentHandler: @escaping (UNNotificationContent) -> Void) {
        self.contentHandler = contentHandler
        bestAttemptContent = (request.content.mutableCopy() as? UNMutableNotificationContent)

        if let bestAttemptContent = bestAttemptContent {
            handleContent(bestAttemptContent: bestAttemptContent)

            contentHandler(bestAttemptContent)
        }
    }

    override func serviceExtensionTimeWillExpire() {
        if let contentHandler = contentHandler, let bestAttemptContent =  bestAttemptContent {
            handleContent(bestAttemptContent: bestAttemptContent)

            contentHandler(bestAttemptContent)
        }
    }

    func handleContent(bestAttemptContent: UNMutableNotificationContent) {
        if let data = bestAttemptContent.userInfo as? [String: Any], let aps = bestAttemptContent.userInfo["aps"] as? [String: Any], let alert = aps["alert"] as? [String: Any] {
            if let locKey = alert["loc-key"] as? String, let locArgs = alert["loc-args"] as? [String] { 
                bestAttemptContent.body = //Uptaded notification text
            }
        }
    }
}

Answer 3

实际上，您可以 select 参数 %<parameter index starting with 1>$@

例如，我可以在 Localizable.strings 文件中写入： "localized_pn_text" = "%2$@, you got a push notification"
