ios - 使用 GCM 在 IO 中实现推送通知

Question

我已经实现了谷歌云消息传递。我收到通知。但我不知道如何将其转换为推送通知。谁能帮我这个？我从 GCM 收到此结果收到通知:[消息:Simon 在您的个人资料中刷了"is"，collapse_key:do_not_collapse，来自:857170554763]

这是代码。有人可以帮我吗？

在GCM Notifications docs上找到了这个.

If you want to send messages consisting of only custom key/values to an iOS device when the app is in the background, set custom key/value pairs in data and set "content_available" to true. It seems that maybe the missing part of your code.

示例:

 {
  "to": "gcm_token_of_the_device",
  "content_available":true,
  "notification": {
    "sound": "default",
    "badge": "2",
    "title": "default",
    "body": "Test Push!"
  }
}
