Detail view button opens another detail view according to sqlite db

I have a sqlite db and I'm populating the table view with it. Every cell opens a detail view accordingly. In this detail view I have some buttons which will have to open other detail views, (one an image view, one a map view, one to download a pdf file) but all of these will have to show things depending on the table view row selected in the first place. How can I do that? Thanx
