Ios 在PubNub Swift中访问PNMessageResult

根据以下功能，我能够收到响应

func client(client: PubNub!, didReceiveMessage message: PNMessageResult!) {
println(message)

但是，我只能以message.data的格式访问数据，该格式为PNMessageData

即使这样，也会以以下格式返回数据：

{
message = "{}";
subscribedChannel = 123;
timetoken = 14392105288780634;}

如何访问message.data（PNMessageData）中message的值？

您已经非常接近访问数据了。SDK序列化接收到的JSON，并将消息作为字典存储在message.data.message上，后者应该是字典

试试这个：

func client(client: PubNub!, didReceiveMessage message: PNMessageResult!) {
    let dictionary: AnyObject = message.data.message
    println(dictionary["accelertiony"]);
    println(dictionary["accelerationx"]);
}

我已经编写了解析PNMessageResult的简单方法

func client(_ client: PubNub, didReceiveMessage message: PNMessageResult) {

    //Message Received on Channel:
    let channel = message.data.channel

    //Message Received:
    guard let messageData = message.data.message as? [String : AnyObject] else { return }

    //Event:
    guard let event:String = messageData["event"] as? String 

    let data:AnyObject = messageData["data"] else { return }

    guard let dict = data as? NSDictionary else { fatalError("Couldn't parse pubnub message") }

    //This will be message in dictionary
    let mutableDict = dict.mutableCopy() as! NSMutableDictionary

}

虽然很少有更改，但服务器发布的数据是反序列化的，并且只有在此之后才能工作。var错误：N错误？设x=NSJSONSerialization.JSONObjectWithData（（字典为！NSString）。数据使用编码（NSUTF8StringEncoding，allowossyconversion:true）！，选项：NSJSONReadingOptions.MutableContainers，错误：&错误）为！字典
