Objective-C Corutin

Question

Objective-C - how can I create an objective-c coroutine? When I have an IBAction called by a button, it freezes the application until IBAction completes the data extraction (from the website). How can I run this run as a coroutine for the main application?

Thanks Christian Stewart
