ios - 无法将 Bool 类型的值分配给类型 String 数据库表示

Question

如何将非字符串类型的数据添加到 DatabaseRepresentation。我尝试过 AnyObject，但不符合哈希协议(protocol)。

lastMessageRead 是 Bool 类型还是我只是将其存储为字符串？

extension Channel: DatabaseRepresentation {

    var representation: [String : Any] {
        var rep = ["ownerName": ownerName]
        rep["ownerId"] = ownerId
        rep["participantName"] = participantName
        rep["participantId"] = participantId
        rep["lastMessage"] = lastMessage
        rep["lastMessageId"] = lastMessageId

        if let lastMessageRead = lastMessageRead {
            rep["lastMessageRead"] = lastMessageRead **Cannot assign Bool to String
        }

        if let id = id {
            rep["id"] = id
        }
        return rep
    }
}

你可以试试这个:

var representation: [String : String]

rep["yourData"] = "\(your data)"

对于日期:

    let formatter = DateFormatter()
    formatter.dateStyle = DateFormatter.Style.medium
    formatter.timeStyle = DateFormatter.Style.none
    formatter.dateFormat = "dd.MM.yyyy"
    let text = formatter.string(from: yourDateValue)
    rep["yourDate"] = text

希望能帮助到你...
