在swift 3.0中使用XMPP openfire发送消息

import XMPPFramework

let xmppStream = XMPPStream()
xmppStream.addDelegate(self, delegateQueue: DispatchQueue.main)

let jid = XMPPJID(string: "your_username@your_domain")
xmppStream.myJID = jid

let hostName = "your_xmpp_server_address"
let hostPort: UInt16 = 5222

do {
    try xmppStream.connect(withTimeout: XMPPStreamTimeoutNone)
} catch {
    print("Failed to connect to XMPP server")
}

extension YourViewController: XMPPStreamDelegate {
    func xmppStreamDidConnect(_ sender: XMPPStream!) {
        // 连接成功后进行身份验证
        do {
            try xmppStream.authenticate(withPassword: "your_password")
        } catch {
            print("Failed to authenticate")
        }
    }
    
    func xmppStreamDidAuthenticate(_ sender: XMPPStream!) {
        // 身份验证成功后，可以发送消息
        let message = XMPPMessage(type: "chat", to: XMPPJID(string: "recipient_username@recipient_domain"), elementID: xmppStream.generateUUID())
        message?.addBody("Hello, world!")
        
        xmppStream.send(message)
    }
    
    func xmppStream(_ sender: XMPPStream!, didReceive message: XMPPMessage!) {
        // 处理接收到的消息
        if let body = message.body {
            print("Received message: \(body)")
        }
    }
}
