代码中用到的工具类

import Foundation
import XMPPFramework

class ZJ_Xmpp{
    static func stringValue(_ element:DDXMLElement?) -> String{
 
        if(element == nil){
            return "";
        }else{

            return element!.stringValue!;
        }
    }
    
    static func stringValue(_ node:DDXMLNode?) -> String{

        if(node == nil){
            return "";
        }else{
            
            return node!.stringValue!;
        }
    }
}

用户状态改变的代理(暂时没用)

import Foundation
protocol ChatDelegate{
    func newBuddyOnline(buddyName:String)
    func buddyWentOffline(buddyName:String)
    func didDisconnect()
}

接受消息的代理(通知消息列表页面刷新)

import Foundation
protocol MessageDelegate {
    func newMessageReceived(sendMsg: SendMsg)
}
