我在特定端口上接收消息时遇到问题。发送工作正常。
代码如下:
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)
}
}
我在网络统计中看到应用程序正在接收数据包: Packets
但我在控制台中看不到任何东西。 一些想法?
答案 0 :(得分:0)
在委托函数之前添加:func udpSocket(....)该属性
@objc(udpSocket:didReceiveData:FROMADDRESS:withFilterContext:)
XCode 8会发出警告,但不注意,UDP数据包会到达。
