UISplitView master view button through storyboard

Evening,

Firstly, I apologise for my code - I am too aware of its bugs; once I have all running as I want I shall be going back and addressing it.

I have a split view ipad storyboard (table and detail) which shares its code with the iphone storyboard. It works fine. However, I want the master view for the ipad to remain in view all times. Otherwise, to have a button to bring it into view. I have looked a tutorials and added the methods I’ve found online into various parts of my code trying to get it to work to no avail. My code is below - one VC supplies the table data and the other the detail view. I have tried dragging the toolbar and toolbar item onto the storyboard and linking that via segue to the table view - but it crashes the second time I click the button.

Summary: How do I 1) add a button to the storyboard to bring the master to view whilst sharing the view controllers. 2) how do I permanently have the master in view sharing view controllers.

The RCVC is master, detailVC detail view

Thank you

The iPad storyboard takes this format - the SplitViewController, leading to a nav controller and table view (master) and the detail view being a view with a number of labels and adbanner. I've used a replace segue between the detail view and master view which works - I'm not sure if this is the wrong thing to do.
