Crash on iOS7 using sockets

[Dario Ogniben]

Hi, i have an issue with CN1 using sockets on iOS.
Everything works fine on the simulator, but when i build and deploy on an iPhone5 with iOS7 the app crashes on Socket.connect(...)
On the app side i have a button that once pressed triggers this action:

    protected void onGUI1_ConnectButtonAction(Component c, ActionEvent event) {       
                    Socket.connect("192.168.11.106", 3333, new SocketConnection() {
                        @Override
                        public void connectionError(int errorCode, String message) {
                            System.out.println("Error");
                        }

                        @Override
                        public void connectionEstablished(InputStream is, OutputStream os) {
                            System.out.println("Connected!");
                        }
                    });
    }

The action makes the app crash with the following report:

ReportCrash[4147] <Notice>: ReportCrash acting against PID 4146
ReportCrash[4147] <Notice>: Formulating crash report for process HS3Application[4146]

That's all. For my app is fundamental the socket communication, so i started from that but i'm quite blocked.
Thanks for any help or advice you can give.

I also tried Steve Hannah CN1Sockets implementation, but my test app crashes with the following error:

HS3Application[4851] <Error>: -[ca_weblite_codename1_net_impl_NativeSocketImpl isInputStreamShutdown]: unrecognized selector sent to instance 0x15d7ad80
HS3Application[4851] <Error>: *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[ca_weblite_codename1_net_impl_NativeSocketImpl isInputStreamShutdown]: unrecognized selector sent to instance 0x15d7ad80'

Anyone has more luck with CN1 sockets and iOS 7 ?
I forgot to mention (if may be important) that my builds are sent by IntelliJ 13.0

I haven't had any problems with the CN1Sockets on iOS 7.   Can you post a simple test case that is failing for you and I'll take a look?  Are you on the newVM or the old one?

Hi Steve, thank you for your interest!

I solved the previous problem by slightly changing a line on ca_weblite_codename1_net_impl_NativeSocketImpl.m, from:

-(BOOL)isSocketConnected{
    return ![self isInputStreamShutdown] && ![self isOutputStreamShutdown];
}

to:

-(BOOL)isSocketConnected{
    return ![self isInputShutdown] && ![self isOutputShutdown];
}

Now the isSocketConnected method seems to work fine. I have another problem that i'm investigating, but it could be due to a firewall policy.
I'm using the old VM and a simple test case, a button that when pressed tries to establish a socket connection.

Thanks
Dario
