Navigation bar style in popover view controller

In iPhone SDK 4.2.3, use default Split View template to cook-up a dummy application.

In landscape mode, the master view uses default navigation bar style. In portrait mode, the master view uses black navigation bar style inside the popover. How can i change the bar style/tint color to make it consistent for both views?

I've tried to do this in split view delegate method, but it doesn't work.

pc.contentViewCon开发者_高级运维troller.navigationController.navigationBar.barStyle = UIBarStyleDefault;
pc.contentViewController.navigationController.navigationBar.tintColor = [UIColor redColor];

I've also tried to explicitly set the navigation bar style in the master view controller class, but that doesn't seem to have any impact as well.

After playing around, i can safely say that it's not possible.
