问题

[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

but when i came back from an image picker from gallery iOS reuse black color and use it in all the application. Why?

Hi using this method you can manage the navigation bar

 - (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated
    {

        [viewController.navigationItem setTitle:@"Videos"];
        [viewController.navigationController.navigationBar setTintColor:[UIColor whiteColor]];
        [viewController.navigationItem.leftBarButtonItem setTintColor:[UIColor whiteColor]];
        [viewController.navigationItem.rightBarButtonItem setTintColor:[UIColor whiteColor]];

        if ([navigationController isKindOfClass:[UIImagePickerController class]]) {
            [[UIApplication sharedApplication] setStatusBarHidden:NO];
            [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent animated:NO];
        }
    }

Thanks
