Question

我正在尝试读取UNNotificationResponse的userInfo对象。我尝试将其投射到Dictionary。但它返回nil。

我打印了对象。

let userInfo = response.notification.request.content.userInfo
if let messageID = userInfo["taskDoc"] {
            print("Message ID: \(messageID)")
}

它会打印以下内容。

{"assigned_user":"+sddadad","assigned_user_image":"","assigned_user_name":"Chandima 68","assignee_comment":"","checklist":[],"created_at":{"_seconds":1559297826,"_nanoseconds":851644000},"created_by":"+94711555268","description":"","due_at":{"_seconds":1559297824,"_nanoseconds":745725000},"group_id":"I0W3Nrrr0IpUVaI33SnU","group_name":"Photo Group new","status":0,"title":"Ada","updated_at":{"_seconds":1559297826,"_nanoseconds":851644000}}

但是当我尝试投射对象时，它返回nil。

let task = userInfo["taskDoc"] as? Dictionary<String, Any>

Answer 1

要获取userInfo["taskDoc"]的值，您可以像这样

let test = userInfo["taskDoc"] as? NSDictionary

如果您希望获取通知的信息，可以按照以下方式进行操作

let title = response.notification.request.content.title
let subtitle = response.notification.request.content.subtitle
let body = response.notification.request.content.body

无法从Swift读取FCM消息内容
