Any suggestions?

Answer 1

Because in ios7 navigationBar color should taken from view background color

 -(void)viewDidDisapper{

     self.navigationController.navigationBar.barTintColor = [UIColor redColor];// Your nav image
    }

 -(void)viewWillDisapper{

     self.navigationController.navigationBar.barTintColor = [UIColor redColor];// Your nav image
    }

or set your appdelegate in case your common UINavigation Bar image throughout project

[[UINavigationBar appearance] setTintColor:[UIColor barColor]];

Answer 2

I finally found the answer! you have to set at your root view controller (where the action to the partial curl triggers) extend edges under top bar!
