在我的xamarin.ios项目中,使用自定义渲染器来实现透明的主详细信息页后,我现在遇到的问题是,在实现此功能后,我注意到主详细信息页的外部有一个灰色边框,我尝试通过几个属性来访问它,但似乎都不起作用。
以下是客户呈现程序代码
public override void ViewWillLayoutSubviews()
{
base.ViewWillLayoutSubviews();
var master = ViewControllers[0];
master.View.BackgroundColor = UIColor.Clear;
var detail = ViewController.ChildViewControllers[1];
}
下面是用于设计侧菜单的xaml代码:
