Broken navigation in UIImagePickerController

There seems to be problem with hiding status bar in UIImagePicker/UIPopoverController , below code is used to hide status bar but in UIImagePickerController navigation breaks when swiped back(In the image below you can see back button is gone).Any solution for this?

-(BOOL)prefersStatusBarHidden
{
    return YES;
}

-(void)viewWillAppear:(BOOL)animated
{
    [[UIApplication sharedApplication] setStatusBarHidden:YES];

}

- (void)popoverControllerDidDismissPopover:(UIPopoverController *)popoverController
{
    [[UIApplication sharedApplication] setStatusBarHidden:YES];
}

-(void)navigationController:(UINavigationController *)navigationController
     willShowViewController:(UIViewController *)viewController
                   animated:(BOOL)animated
{
    [[UIApplication sharedApplication] setStatusBarHidden:YES];
}
