Slide Out Navigation not working when I use revealToggle: method (SWRevealViewController Class)

Question

I have successfully implemented SWRevealViewController Class in my project.

https://github.com/John-Lluch/SWRevealViewController

But when I use revealToggle: method as my left bar button item action, it shows a complete black screen. The View is completely black. But when I use rightRevealToggle: method, the view loads normally.

I'm including the code of AppDelegate.h,AppDelegate.m and Main view.

Slide out view is an empty view now. Just background colour changed.

Check it and let me know what is wrong.

Here is the screenshot of the project in simulator
