GCDAsyncSocket這個(gè)框架有接近1萬(wàn)個(gè)star,six six six .
即時(shí)通訊我們用的是TCP協(xié)議進(jìn)行通訊.
準(zhǔn)備:先下載GCDAsyncSocket框架,和到MAC商店下載一個(gè)xSocket測(cè)試工具.
第一步:建橋文件,在橋文件中加入#import "GCDAsyncSocket.h"
第二步: 在對(duì)應(yīng)的 控制器里定義一個(gè)端口,你電腦的IP地址和GCDAsyncSocket對(duì)象
let serverPort: UInt16 = 8080
var host = "222.2.11.127"
var sendSocket:GCDAsyncSocket?
第三步:在viewDidLoad中寫(xiě)連接方法,已進(jìn)入頁(yè)面就使其連接,添加協(xié)議GCDAsyncSocketDelegate
sendSocket = GCDAsyncSocket(delegate: self, delegateQueue: DispatchQueue.global(qos: .default))
do {
try sendSocket?.connect(toHost: host, onPort: UInt16(serverPort))
print("連接--成功")
}catch _ {
print("失敗")
}
第四步:添加代理方法
func socket(_ sock: GCDAsyncSocket, didAcceptNewSocket newSocket: GCDAsyncSocket) {
//開(kāi)始接受數(shù)據(jù)
sendSocket?.readData(withTimeout: -1, tag: 0)
}
//讀到數(shù)據(jù)后的回調(diào)代理
func socket(_ sock: GCDAsyncSocket, didRead data: Data, withTag tag: Int) {
//后臺(tái)給的是字符串的時(shí)候
// let str = String.init(data: data, encoding: .utf8)
// print(str as Any)
// DispatchQueue.main.async {
// self.labelStr.text = str
// }
//后臺(tái)返回的是json的時(shí)候
let json = JSON.init(data: data)
print(json)
sendSocket?.readData(withTimeout: -1, tag: 0)
}
func socket(_ sock: GCDAsyncSocket, didConnectToHost host: String, port: UInt16) {
print(host)
print("連接成功")
//發(fā)起一個(gè)讀取的請(qǐng)求箱靴，當(dāng)收到數(shù)據(jù)時(shí)didReadData才能被回調(diào),設(shè)置一個(gè)分割,也就是讀到某個(gè)data的時(shí)候就會(huì)停止(分隔符即為0A).可以解決丟包問(wèn)題
sendSocket?.readData(to: GCDAsyncSocket.lfData(), withTimeout: -1, tag: 0)
// sendSocket?.readData(withTimeout: -1, tag: 0)
}
func socketDidDisconnect(_ sock: GCDAsyncSocket, withError err: Error?) {
print("斷開(kāi)連接")
}
第五步:使用xSocket建立本地服務(wù)
選擇server

然后點(diǎn)擊start service運(yùn)行程序就可以進(jìn)行通訊了

完成!!!!
