如何在iOS远程消息中处理其他数据GCM

Question

我正在通过Google云消息接收远程通知。弹出一条消息，徽章附加到应用程序项目，声音也正常工作。现在我正在尝试访问其他数据，但有点挣扎。这就是消息的样子：

Notification received: [gcm.notification.shops: ["548","525"], gcm.message_id: 0:1472546619970126%1dfec10a1dfec10a, gcm.notification.vibrate: 1, aps: {
alert =     {
    body = "2 neue Gutscheine verf\U00fcgbar";
    title = "Neue Gutscheine";
};
  badge = 2;
  "content-available" = 1;
  sound = 1;
}]

我现在如何访问商店阵列？这不起作用：

var shops :[String] = userInfo["shops"] as! [String]

我正在尝试在didReceiveRemoteNotification（）函数中处理它。

Answer 1

将元素从数组更改为字符串并在最后将其转换为数组就可以了：

 if let v = userInfo["gcm.notification.shops"] as? NSString{
   let new_vouchers_string = v.componentsSeparatedByString(",")
   let new_vouchers = new_vouchers_string.map { Int($0)!}
 }
