Here is my view hierarchy
Input ----> Control Panel (board controller with 3 VC). From one VC panel controller 4 VCs are presented one after the other modally.
----> VC1 ----> VC2 ----> VC3 ----> VC4.
1. How to return to the control panel controller from VC4?
2.My application crashes several times due to memory. Since I do not have a return button in all view controllers, I want to remove VC1 from memory by representing VC2 and VC2 when representing VC3 etc. What is the best way to achieve this?
3. I have an exit button to one of my view controllers in a tab. What is the best way to present a magazine on screen? (I have currently connected segue to login. Is this correct?)
Thanks..
