I guess you basically understand how we map the Cocoa API to the Java
version ;-) So probably your question is about the selector argument of
the call you pointed us to.
Basically we decided to map this kind of API to a strongly typed
interface. For the implementation that means
* we define an interface which specifies a callback method
* so our API's version of the method you mentioned does not have the
selector parameter
* our Objective C implementation would pass
action:@selector(<callbackMethod>) to initWithBarButtonSystemItem
As an example have a look at the already existing method
UIControl.addTarget in the following files: UIControl.java,
UIControlDelegate.java and org_xmlvm_iphone_UIControl.m
If this doesn't help please let me know.
