Passing objects in tabbarcontroller

Question

Hi everyone,

I'm developing a tabBarController-based application, and I'm not able to pass information from one tab to another. Each one is a different class, and I would like to generate info with one tab and store it in an instance of a different class, then pass this instance to a different tab, and use that info, or generate and store there new.

I'd like to make myself clearer, but not easy to explain.

Thank you very much
