I have been banging my head and moving things around on this for a while. Maybe a (much more) experienced developer will immediately see the error of my ways?
From logs I can see that:
I enter the init method, which leads into the initWithParentViewController method. Then I go into viewDidLoad. Then, in initWithParentViewController, I proceed to:
[self.view addSubview:table_To_Enter_First_TriView];
and then back into viewDidLoad (for the second time).
After leaving viewDidLoad I immediately crash with:
....TriViewController superview]: unrecognized selector sent to instance...
I am providing most of the .m file here although I believe the problem to be in the init or initWithParentViewController methods.
I really appreciate your help!
