XCode 5, iOS7 project, using Storyboard, but mostly to define the flow, no UI is created by it.
I have this scenario (sorry for no screenshot, but the storyboard is actually pretty big):
I've setup ECSlidingViewController as it should. It's initial VC (the subclass of ECSlidingViewController) is rootVC and inside him I define the under ViewController and top ViewController.
I have UITableVC with embed in UINavigationVC as underLeftViewController. As my topViewController I have UITabbarVC with three tabs. Each of the childVC of the Tabbar has its own navigationBar a button which opens the side menu (underLeftViewController).
In one of my tabs I have UITableVC with embed in UINavigationVC. Lets call this one Screen1.
When pressed on some row I push PSCollectionView (collectionView with customisable cell). A grid displaying image thumbnails. Lets call this one Screen2.
When pressed on some image, I push fullscreen image. This one is Screen3.
There is a button which when pressed it presents a modalVC with embed in UINavigationVC which present image details.
Now when I dismiss the modalVC I'm back on Screen3. Then I press back and from Screen3 i go back to Screen2 successfully, but then when i press back once again to navigate to Screen1 (first tab of the tabbarVC where the side menu button is) the app crushes with this error:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UnderViewController _mainContext]: unrecognized selector sent to instance 0xa640610'
I can't find what actually is happening. I don't even try to reach UnderViewController (even if I want I can't - no button to display it). Searched on the Internet for some solution, but nothing. Seems like I'm the only one with this problem, so I must be doing something wrong.
Just to mention, in underLeftViewController when selected row from different section I present modalVC which when i dismiss it, the app is still functioning without problem. The problem arise only in that scenario.
Any tips, suggestions are welcome.
