NATIVE IOS CODE CALLBACKS

If you are experiencing an issue please mention the full platform your issue applies to:
IDE: NetBeans/Eclipse/IDEA

As you mentioned in native iOS call back to call a function from iOS with NSString arg 

public static void callback(String arg) {

}

we should use fromNSString this a call like:

fromNSString(CN1_THREAD_GET_STATE_PASS_ARG nsStringValue); 

how to do the same to call this interface from iOS:

public static void callback(byte[] arg) {

}

My objective is to call an interface with byte[] arg with NSData* argument (NSData represent a data from an image)

Here's an example from the Websocket cn1lib doing exactly this.
