cannot load left menu when adding a new view controller

[Steven]

Hi,

I want to add a new row index of the left menu as feedback and I tried what the example did in README. It does load the view controller but the background color is wrong(it actually shows the root view controller color) and when I tried to go back to left menu, the left button in the navigation bar is not responding.

This issue may sound pretty newbie but I am really stuck in it for couple hours.
I posted the code and picture below. Any advice is appreciated, thanks a lot.

I add a new case in DEMOLeftMenuViewController.m

create a subclass of RESideMenu as FeedbackViewController.

And link FeedbackViewController using push segue in storyboard, its background color is green but it runs in simulator as grey (same as the color of rootViewController)

When I go to the FeedbackView, the left button in the navigation bar is not responding when I tried to click it.

I found the problem was that: create a subclass of UIViewController instead of RESideMenu. I wrote here in case others have the same issue
