導入AsynSocket庫,導入CFNetwork系統庫
1.新建single view工程
ViewController.h文件
#import#import "AsyncSocket.h" @interface ViewController : UIViewController { NSMutableArray *_socketArray; AsyncSocket *_sendSocket;//發送 AsyncSocket *_recvSocket;//接收 } - (IBAction)sendClick:(id)sender; @property (retain, nonatomic) IBOutlet UITextField *ipField; @property (retain, nonatomic) IBOutlet UITextField *sendField; @property (retain, nonatomic) IBOutlet UITextView *msgView; - (IBAction)conClick:(id)sender; - (IBAction)sendClick:(id)sender; @end
#import "ViewController.h" @implementation ViewController @synthesize ipField; @synthesize sendField; @synthesize msgView; - (void)viewDidLoad { [super viewDidLoad]; //初始化socket數組,存放socket _socketArray = [[NSMutableArray alloc] init]; //實例化客戶端和服務器socket _sendSocket = [[AsyncSocket alloc] initWithDelegate:self]; _recvSocket = [[AsyncSocket alloc] initWithDelegate:self]; //服務器段開始監聽 [_recvSocket acceptOnPort:5566 error:nil]; } //服務器端接收到新的socket - (void)onSocket:(AsyncSocket *)sock didAcceptNewSocket:(AsyncSocket *)newSocket { //服務器端將收到的socket存入數組 [_socketArray addObject:newSocket]; //開始接收數據 [newSocket readDataWithTimeout:-1 tag:0]; } //服務器端接收到信息 - (void)onSocket:(AsyncSocket *)sock didReadData:(NSData *)data withTag:(long)tag { NSString *string = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; self.msgView.text = [NSString stringWithFormat:@"%@%@:%@\n", self.msgView.text, sock.connectedHost, string]; [sock readDataWithTimeout:-1 tag:0];//循環 } //連接 - (IBAction)conClick:(id)sender { if (_sendSocket.isConnected) { [_sendSocket disconnect]; } [_sendSocket connectToHost:self.ipField.text onPort:5566 withTimeout:30 error:nil]; } //發送消息 - (IBAction)sendClick:(id)sender { NSData *data = [self.sendField.text dataUsingEncoding:NSUTF8StringEncoding]; [_sendSocket writeData:data withTimeout:30 tag:0]; self.sendField.text = @""; } - (void)onSocket:(AsyncSocket *)sock didConnectToHost:(NSString *)host port:(UInt16)port { NSLog(@"連接服務器成功"); } - (void)onSocketDidDisconnect:(AsyncSocket *)sock { NSLog(@"斷開連接"); } - (void)dealloc { [ipField release]; [sendField release]; [msgView release]; [ipField release]; [super dealloc]; } - (void)viewDidUnload { [self setIpField:nil]; [super viewDidUnload]; } @end
