Custom nav bar with UIImagePickerControl

I have replaced the nave bar in my iOS7 app in Xcode 5 using the following code (also removed the status bar if that matters):

AppDelegate.M

[[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:@"navBar"] forBarMetrics:UIBarMetricsDefault];

In one of my image view controllers I am using a UIImagePicker to pick a profile pic. The problem is when it goes to the photo gallery it uses the main "navBar" image which hides some controls and basically stacks 2 of the same nav bars on top. Can I have a different nav bar for the photogallery? Here is the View controllers:

FirstView.H

#import <UIKit/UIKit.h>

@interface IBFirstViewController : UIViewController <UIImagePickerControllerDelegate, UINavigationControllerDelegate>


@property (weak, nonatomic) IBOutlet UILabel *userName;
@property (weak, nonatomic) IBOutlet UILabel *userEmail;
@property (weak, nonatomic) IBOutlet UIImageView *backgroundImage;


- (IBAction)logout:(id)sender;
- (IBAction)edit:(id)sender;
@end

FirstView.M

- (IBAction)edit:(id)sender {
    UIImagePickerController *imagePickerController = [[UIImagePickerController alloc]init];
    imagePickerController.modalPresentationStyle = UIModalPresentationCurrentContext;
    imagePickerController.delegate = self;
    [self presentViewController:imagePickerController animated:NO completion:Nil];
}

So you are saying the imagePicker controller is using the image you set in your app delegate correct? If you wanted to change the image just for that imagePickers bar, maybe you could try using the following delegate method:

    - (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated
{
    if ([viewController isKindOfClass:[UIImagePickerController class]] {

    //customize your navigationController here
    [navigationController.navigationBar setBackgroundImage:[UIImage imageNamed:@"navbar.png"]    forBarMetrics:UIBarMetricsDefault];

    }
}

and then maybe change the image back when the imagePicker controller is dismissed?
