Navigation Bar hiding when moving to new view controller

When I am trying to move from one view controller to other by pressing on a table view cell in the present view controller. The problem is when I do this :

FGTipViewController *vc = [[FGTipViewController alloc] initWithNibName:@"FGTipViewController" bundle:nil];

[self.navigationController pushViewController:vc animated:YES];

It takes me to the new view controller but the navigation bar disappears. This happens for a particular view controller only and works fine for others. I am not able to make out any elementary difference between these classes. What could be the cause of this kind of problem? Let me know if more details are required.

Try these lines when you push your view,

FGTipViewController *vc = [[FGTipViewController alloc] initWithNibName:@"FGTipViewController" bundle:nil];

[self.navigationController pushViewController:vc animated:YES];
[self.navigationController setNavigationBarHidden:NO animated:YES];

And also in the viewWillAppear method of FPTipViewController,

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];

    [self.navigationController setNavigationBarHidden:NO animated:YES];
}

I did this and it works. Thanks!

UINavigationBar* navBar = self.navigationController.navigationBar;

    if (navBar) {
        [UIView animateWithDuration:ANIMATION_DURATION animations:^{
            [navBar setFrame:CGRectMake(0, 20, navBar.frame.size.width, navBar.frame.size.height)];
        }];
    }

In FGTipViewController,

-(void) viewWillAppear:(BOOL) animated {

    [super viewWillAppear];
    [[self navigationController] setNavigationBarHidden:NO animated:YES];

}
