Please help me. I'm developing chat using XMPP in iPhone.I want to send image file and emoticons when user chat message,but I get failed as following:

   

- (void)turnSocketDidFail:(TURNSocket *)sender {
    
    NSLog(@"TURN Connection failed!");
    [turnSockets removeObject:sender];
    
}

- (void)turnSocket:(TURNSocket *)sender didSucceed:(GCDAsyncSocket *)socket {
    
    NSLog(@"TURN Connection succeeded!");
    NSLog(@"You now have a socket that you can use to send/receive data to/from the other person.");
    NSData *dataF = [[NSData alloc] initWithContentsOfFile:
                     [[NSBundle mainBundle] pathForResource:@"defaultPerson" ofType:@"png"]];
    
    [socket writeData:dataF withTimeout:60.0f tag:0];

    
    [turnSockets removeObject:sender];
}
