Navigationcontroller is not showing while loading the app for first time

[AnilkumarRabhasa]

i am an iOS apps developer. my requirement is splitviewcontroller for universal app. So, i have checked so many forums and found this api. This api is very easy to integrate to project, I followed example app. But i am facing issue is while loading first time app, the navigationcontroller is not displaying. At the second time loading app, that time only navigationcontrolle is coming. So, please fix this bug.

Thanks Anilkumar
