Passing arguments between cocoa apps

Question

I need to pass the values between 2 cocoa application.I have explored 2 ways -

Using NSDistributionNotification Center as in the below - how to pass parameters between cocoa applications

Problem here is this is does not seems to work in sandboxed scenario.

Using MDAdditions class as in Pass arguments between Objective-C applications

Not sure, If this works in sandbox scenario. Problem here is I am not able to get changed arguments when it is reopen from dock scenario. It shows initial argument passed.Every time app2 is called/invoked from app1, different arguments will be passed. First time when app2 is opened, I am getting param. But when I hide/minimize app2 and it becomes active again (when app2 is called again from app1), it is not getting new argument. I need the param in applicationDidBecomeActive:.

Any solution for the above case?

dist notifs dont work in sandbox mode for sure – Daij-Djan Mar 05 '14 at 16:59 — Daij-Djan, Mar 05 '14 at 16:59

the recommended way is to use XPC to pass arguments from one app to another as I get it

that works in sandbox mode too

but XPC is async and you cant guarantee the param is available when you need it to be – Daij-Djan Mar 05 '14 at 16:58
