PushViewController with NavigationBarHidden = YES about tlyshynavbar

Hi @basilmariano, I am glad you liked it.

If I understand the question correctly, you are making the setNavigationBarHidden: call in a view controller that uses the shyNavBar? If that is the case, it probably won't work, since you are hiding the navigation bar anyway, why would you want to attach the shyNavBarManager to it?

If you mean the shyManager is attached to the previous controller, it should work, I just tested it myself. Make sure your call is like this:

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
    [self.navigationController setNavigationBarHidden:YES animated:animated];
}

Cheers,

If you are pushing to a view controller that does not have a shyNavBar from a view controller that does have a shyNavBar and you are hiding the nav bar in viewWillAppear of the new controller it will not work. Here is the solution that works great for me.

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

    //We have to manually animate hiding the nav bar because TLYShyNavBar prevents
    //[self.navigationController setNavigationBarHidden:YES animated:YES]; from animating properly.
    //First animate the bar out in viewWillAppear:, then call setNavigationBarHidden: in viewDidAppear:
    //This will allow user interaction underneath where the bar would normally be.

    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:0.25];
    self.navigationController.navigationBar.alpha = 0;
    [UIView commitAnimations];
}

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

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


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

    //Prevents showing the navigation bar when moving to another of the same controller
    if (![self.navigationController.topViewController isKindOfClass:[YourViewController class]]) {
        [self.navigationController setNavigationBarHidden:NO animated:YES];

        [UIView beginAnimations:nil context:NULL];
        [UIView setAnimationDuration:0.25];
        self.navigationController.navigationBar.alpha = 1;
        [UIView commitAnimations];
    }

}
