How can I show a tabbar when pushing a UIViewController onto the Navigation stack

Question

So it is very easy to hide the tabbar when you push a view controller onto the navigation controller stack:

uiViewController.hidesBottomBarWhenPushed = YES;

works just peachy.

Put let's say I want to push deeper into the stack and show it again?

Setting

 laterUIViewController.hidesBottomBarWhenPushed = NO; 

on some later view controller doesn't make it reappear. It's still hidden.

Answer 1

You could try subclassing UIViewController and overriding the

- (void)viewWillAppear:(BOOL)animated { self.hidesBottomBarWhenPushed = YES; }
- (void)viewWillDisappear:(BOOL)animated { self.hidesBottomBarWhenPushed = NO; }

And then using that subclass as the superclass of the view controller that you want to show the bottom bar.

Answer 2

This worked for me:

- (void)viewWillAppear:(BOOL)animated { self.tabBarController.tabBar.hidden = YES; }
- (void)viewWillDisappear:(BOOL)animated { self.tabBarController.tabBar.hidden = NO; }
