i need to send 4 bytes message like 0x1001 to server and receive answer from it
i use AsyncSocket and wrote the next code:
...
[socket connectToHost:[arr objectAtIndex:0] onPort:theInteger error:&err];
...
-(void)onSocket:(AsyncSocket *)sock didConnectToHost:(NSString *)host
port:(UInt16)port
{
NSLog(@"Connect to %@:%u", host,port);
MTMessageBroker*newBroker = [[[MTMessageBrokeralloc]
initWithAsyncSocket:socket] autorelease];
[sock release];
newBroker.delegate = self;
self.messageBroker = newBroker;
[selfsendConfirmationToServer];
}
-(void) sendConfirmationToServer
{
NSString*myString = @"0x1001";
const char *utfMyString = [myString UTF8String];
NSData *sendMe = [NSData dataWithBytes:utfMyString length:4];
MTMessage *newMessage = [[[MTMessage alloc] init] autorelease];
newMessage.tag = 0;
newMessage.dataContent = sendMe;
[self.messageBroker sendMessage:newMessage];
}
#pragma mark MTMessageBroker Delegate Methods
-(void)messageBroker:(MTMessageBroker *)server didReceiveMessage:(MTMessage
*)message
{
if ( message.tag == 0 )
{
[selfdisplay:@"Message broker"];
NSString*str = [[[NSStringalloc]
initWithData:message.dataContentencoding:NSUTF8StringEncoding] autorelease];
NSLog(@"%@",str);
}
}
- (void)onSocket:(AsyncSocket *)sock didReadData:(NSData *)data
withTag:(long)tag
{
NSData *strData = [data subdataWithRange:NSMakeRange(0, [data length])];
NSString*msg = [[[NSStringalloc] initWithData:strData
encoding:NSUTF8StringEncoding] autorelease];
NSLog(@"%@",msg);
}
