如何更改Xamarin.Forms标签栏高度(iOS)

Question

如何在Xamarin.Forms(iOS)中更改Tab栏的高度？TabbedRenderer可以吗？

Answer 1

是的,这可以从a修改CustomRenderer.

您需要TabbedPage在Forms项目中继承子类并使用此类导出渲染.

然后在CustomRenderer中覆盖该ViewWillLayoutSubviews方法.就像是:

public class MyTabbedPageRenderer : TabbedRenderer
{
    // Modify this variable with the height you desire.
    private readonly float tabBarHeight = 55f;

    public override void ViewWillLayoutSubviews()
    {
        base.ViewWillLayoutSubviews();

        TabBar.Frame = new CGRect(TabBar.Frame.X, TabBar.Frame.Y + (TabBar.Frame.Height - tabBarHeight), TabBar.Frame.Width, tabBarHeight);
    }
}

希望这可以帮助.-
