Thank you very much

NSString *string = fieldTesto.txt;
// I Find an istruction for insert s string in to the CFSocketSend
UInt8 message[] = "Hello world";
CFDataRef data = 
             CFDataCreate(NULL, message, sizeof(message));
CFSocketSendData(s, NULL, data, 0);
CFRelease(data);

You can convert your string to NSData and then use the toll-free bridging to CFData.

NSData *data = [string dataUsingEncoding: NSASCIIStringEncoding];
...
CFSocketSendData(s, NULL, (CFDataRef)data, 0);
