ios - 接收 UDP 消息
<p><p>我在特定端口接收消息时遇到问题。发送工作正常。</p>
<p>代码如下:</p>
<pre><code>import Foundation
import CocoaAsyncSocket
class InSocket: NSObject, GCDAsyncUdpSocketDelegate {
//let IP = "192.168.1.196"
let PORT:UInt16 = 14000
var isocket:GCDAsyncUdpSocket!
override init(){
super.init()
setupConnection()
}
func setupConnection(){
isocket = GCDAsyncUdpSocket(delegate: self, delegateQueue: DispatchQueue.main)
do{
try isocket.bind(toPort:PORT)
try isocket.beginReceiving()
} catch {print("ErrorReceive")}
}
func udpSocket(sock: GCDAsyncUdpSocket!, didReceiveData data: NSData, fromAddress address: NSData!, withFilterContext filterContext: AnyObject!) {
let str = NSString(data: data as Data, encoding: String.Encoding.ascii.rawValue)
print(str)
}
}
</code></pre>
<p>我在网络统计中看到应用程序正在接收数据包:
<a href="http://i.stack.imgur.com/MNz2z.png" rel="noreferrer noopener nofollow">Packets</a> </p>
<p>但我在控制台中看不到任何内容。
一些想法？</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>在委托(delegate)函数前添加:func udpSocket(....) 那个属性</p>
<p>@objc(udpSocket:didReceiveData:fromAddress:withFilterContext:)</p>
<p>XCode 8 会发出警告，但不要注意，UDP 数据包会到达。</p></p>
