Getting a white screen when the application is opened in IOS7

Question

Sometimes I'm getting a white screen when the application is opened. I also killed the app in the task manager and opened it. But when i saw the console the "applicationDidFinishLaunchingWithOptions" method is running as i have included some logs to confirm it. Not getting any crashes. None of the http requests are done in main thread. Though there are core data insertion for which i have used "Core data concurrency" so it will be running in a separate queue. Any help would be greatly appreciated. And right now i'm testing the app through ad-hoc distribution
