Sample showing issue
I have a tabbed page with a page and a page in a navigation controller. On the page with the navigation controller, there is a button that will do a push to another page. When the page is pushed I want to remove the tab bar. And when the user hits back, I want the tab bar to reappear. The property HidesBottomBarWhenPushed on a UIViewController is supposed to do just that.
Setting that property in a Xamarin.ios project works perfectly, does exactly what it is supposed to do.
Setting the property in a custom renderer in a Xamarin.forms project does nothing, the tab bar won't disappear when the page is pushed.
Tested on 18.104.22.168 and 22.214.171.124-pre2
The attached zip has the Xamarin.ios project as well as the Xamarin forms project.
Thanks for the reproduction; setting to confirmed for further investigation.
For others having this problem, found a workaround.
Set TabBarController.TabBar.Hidden to true in a custom renderer.
It will leave an empty space where the bar was, to fix, set the frame to:
TabBarController.View.Subviews.Frame = new CGRect(TabBarController.View.Subviews.Frame.X, TabBarController.View.Subviews.Frame.Y, TabBarController.View.Subviews.Frame.Width, 0);
I can confirm that this is still occurring in Forms 2.5 using the sample project provided.
