    [self.navigationController.navigationBar setHidden:YES];
}

bView.m

-(void)viewWillAppear:(BOOL)animated{

Answer 1

I got what is your problem. You are hiding your navigation bar in the viewWillAppear: method of viewA and you are doing it without animation.

Try this

// This will add an animation like slide out. So you may won't like it.
[self.navigationController setNavigationBarHidden:YES animated:YES];

If it is not working, then add this code in bView.m

- (void)viewWillDisappear:(BOOL)animated {
[self.navigationController setNavigationBarHidden:YES animated:NO];
[super viewWillDisappear:animated]
}
