How to use hidesBottomBarWhenPushed if i want to hide the tabbar for only one kind of controller?

Question

I have gotten in trouble while using hidesBottomBarWhenPushed... I will push three controllers – A, B, and C – into navigationcontroller in order, and I would like to hide bottom tab bar when B is shown.(and A is one of the tabbar controllers)

Does any one have ideas?

Answer 1

In view controller A (which is on the tabBar), when it comes time to present B (no tabBar wanted):

self.hidesBottomBarWhenPushed = YES; // hide the tabBar when pushing B
[self.navigationController pushViewController:viewController_B animated:YES];
self.hidesBottomBarWhenPushed = NO; // for when coming Back to A

In view controller B, when it comes time to present C (tabBar wanted again):

self.hidesBottomBarWhenPushed = NO; // show the tabbar when pushing C
[self.navigationController pushViewController:viewController_C animated:YES];
self.hidesBottomBarWhenPushed = YES; // for when coming Back to B

Answer 2

Instead of setting it in viewDidLoad, I have found that sometimes this is too late. Set it in init or override hidesBottomBarWhenPushed to return YES for views with no bottom toolbar.
