未調用didreaddata方法。使用asyncsocket

Question

我想使用asyncsocket在ios應用程序與windows服務器（由C++編碼）之間進行通信。 ios發送數據包到服務器是好的，但ios不能從服務器讀取數據包。 我已經通過C++測試客戶端的服務器代碼，它工作正常。 這是我的一部分ios代碼。

- (int) connectServer: (NSString *) hostIP port:(int) hostPort{ 

_isBusy = YES; 
client = nil; 
client = [[AsyncSocket alloc] initWithDelegate:self]; 
self.HOST_IP = hostIP; 
self.HOST_PORT = hostPort; 
NSError *err = nil; 
if([client connectToHost:hostIP onPort:hostPort error:&err]) 
    return SRV_CONNECT_SUC; 
else{ 
    return SRV_CONNECT_FAIL; 
} 
} 

- (void)sendMsg:(NSString *)msg 
{ 
if ([client isConnected]){ 
    NSData *data = [msg dataUsingEncoding:NSUTF8StringEncoding]; 
    [client writeData:data withTimeout:-1 tag:0]; 
} 
} 

-(void*) readMsg 
{ 
[client readDataWithTimeout:-1 tag:0]; 
} 

- (void)onSocket:(AsyncSocket *)sock didReadData:(NSData *)data withTag:(long)tag{ 
NSString* aStr = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; 
NSLog(@"Hava received datas is :%@",aStr); 
[aStr release]; 
[client readDataWithTimeout:-1 tag:0]; 
} 

-(void)onSocket:(AsyncSocket*)sock didConnectToHost:(NSString *)host port:(UInt16)port{ 
NSLog(@"Socket is connected!"); 
[client readDataWithTimeout:-1 tag:0]; 
} 

-(void)onSocket:(AsyncSocket *)sock didReadPartialDataOfLength:(NSUInteger)partialLength tag:(long)tag { 
NSLog(@"Received bytes: %d",partialLength); 
} 

我做斷點在他們每個人，僅僅只有didConnectToHost叫，didReadParticalDataOfLength和didReadData不叫。

我有很多次測試，但ios無法讀取任何東西。 任何想法我做錯了什麼？

p.s.我使用asyncsocket不是GCDasyncsocket。 感謝您的時間。

Missing [readMsg];

- (void)sendMsg:(NSString *)msg { 
     if ([client isConnected]){ 
      NSData *data = [msg dataUsingEncoding:NSUTF8StringEncoding]; 
      [client writeData:data withTimeout:-1 tag:0]; 
      [readMsg]; 
     } 
    }
