CFSocket Error: Operation not permitted

[ccp]

Hi.

I wanted to send a photo to a server on my laptop via socket. I created an instance of CFSocket, and configured everything. Now, client(my iphone) and server(my laptop) are connected.

But when i send the photo data, it keeps saying that "Operation not permitted". I know it's not allowed to write files outside of Application Home folder. But is socket now allowed in iPhone? I don't think so, as a lot of apps are using it. Does anyone know how to deal with this?

Here I show you a part of my code:

- (void)sendPhoto:(CGImageRef)image
{

    //Get JPEG data
    NSData *data = UIImageJPEGRepresentation((UIImage*)image, 1.0);

    //Get file descripter
    CFSocketNativeHandle fd = CFSocketGetNative(tcpClient);

    //Check if it's valid
    if (fd < 0) 
        return;

    //Get size
    size_t size = [data length];

    //Send data
    int bytesSent = send(fd,[data bytes],size,MSG_EOR);

    //I should check if bytesSent is -1,
    //but i'm getting this error every time.
    NSLog(@"%s",strerror(errno)); //"Operation not permitted"
}

Thanks.
