説明
Description
When using a Tabbed Page custom renderer, a blank space will be left where the Tab Bar was when the TabBar.Hidden property is set to true. Also, the TabBar frame's height is being reset somewhere between ViewWillAppear and ViewDidAppear. TabBar height can be forced to 0 by overriding the View property and setting the TabBar frame height to 0.
Steps to Reproduce
- Create a Tabbed Page Custom Renderer.
- Set the TabBar.Hidden property to true in the constructor.
- Set the TabBar.Frame height to 0 in the ViewWillAppear method.
Expected Behavior
Tab Bar is not visible, page stretches to fill now empty space.
Actual Behavior
Tab Bar is hidden, page does not stretch leaving a blank space where the Tab Bar was.
