客戶端應用程序在使用AsyncSocket時無法按預期工作

Question

我在簡單的客戶端 - 服務器應用程序中使用AsyncSocket類。作爲第一步，我希望這一點 - 只要客戶端和服務器之間建立連接，客戶端就會發送一條歡迎消息 - 「連接到xyz服務器」到服務器，服務器以textview顯示它。

//The code in ClientController class is: 

-(void)awakeFromNib{ 
NSError *error = nil; 
    if (![connectSocket connectToHost:@"192.168.0.32" onPort:25242 error:&error]) { 
    NSLog(@"Error starting client: %@", error); 
    return; 
    } 

    NSLog(@"xyz chat client started on port %hu",[connectSocket localPort]); 
} 
- (void)onSocket:(AsyncSocket *)sock didConnectToHost:(NSString *)host port:(UInt16)port{ 
       [sock writeData:[@"connected to xyz server" dataUsingEncoding:NSUTF8StringEncoding] withTimeout:30.0 tag:0]; 
} 
- (void)onSocket:(AsyncSocket *)sock didReadData:(NSData *)data withTag:(long)tag{ 
       // some relevant code goes here 
} 
- (void)onSocket:(AsyncSocket *)sock didWriteDataWithTag:(long)tag{ 
       NSLog(@"within didWriteDataWithTag:"); // getting this message, means it should have written something to remote socket but 
    // delegate- onSocket:didReadData:withTag: at server side is not getting invoked 
} 

// The code in ServerController class is: 

- (IBAction)startStop:(id)sender{ 
NSLog(@"startStopAction"); 
if(!isRunning) 
{ 
    NSError *error = nil; 
    if(![listenSocket acceptOnPort:INPUT_PORT error:&error]) 
    { 
    NSLog(@"Error starting server: %@", error); 
    return; 
    } 

    NSLog(@"Echo server started on port %hu",[listenSocket localPort]); 
    isRunning = YES; 

    [sender setTitle:@"Stop"]; 
} 
else 
{ 
    // Stop accepting connections 
    [listenSocket disconnect]; 

    // Stop any client connections 
    int i; 
    for(i = 0; i < [connectedSockets count]; i++) 
    { 
    // Call disconnect on the socket, 
    // which will invoke the onSocketDidDisconnect: method, 
    // which will remove the socket from the list. 
    [[connectedSockets objectAtIndex:i] disconnect]; 
    } 

    NSLog(@"Stopped Echo server"); 
    isRunning = false; 

    [sender setTitle:@"Start"]; 
} 
} 
- (void)onSocket:(AsyncSocket *)sock didAcceptNewSocket:(AsyncSocket *)newSocket{ 
[connectedSockets addObject:newSocket]; 
} 
- (void)onSocket:(AsyncSocket *)sock didConnectToHost:(NSString *)host port:(UInt16)port{ 
NSLog(@"Accepted client %@:%hu", host, port); // it is getting displayed 
[sock readDataToData:[AsyncSocket CRLFData] withTimeout:READ_TIMEOUT tag:0]; 
} 
- (void)onSocket:(AsyncSocket *)sock didReadData:(NSData *)data withTag:(long)tag{ 
     NSString *msgReceived = [[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding] autorelease]; 
NSLog(@"msgReceived in didReadData- %@",msgReceived); // it is not getting displayed 
     [outputView insertText:msgReceived]; 
     [sock readDataToData:[AsyncSocket CRLFData] withTimeout:READ_TIMEOUT tag:0]; 
} 

任何人都可以建議我在哪裏可能是錯誤的？ 在此先感謝...... Miraaj

問題解決：剛剛使用：[sock readDataWithTimeout：READ_TIMEOUT tag：0];代替：[sock readDataToData：[AsyncSocket CRLFData] withTimeout：READ_TIMEOUT tag：0];
