如何在xamarin.ios原生应用程序中显示DisplayActionSheet

// 在需要显示ActionSheet的事件处理方法中
private void ShowActionSheetButton_Clicked(object sender, EventArgs e)
{
    // 创建UIAlertController对象
    UIAlertController actionSheet = UIAlertController.Create("选择操作", null, UIAlertControllerStyle.ActionSheet);

    // 添加选项按钮
    actionSheet.AddAction(UIAlertAction.Create("选项1", UIAlertActionStyle.Default, (action) =>
    {
        // 选项1的点击事件处理
        Console.WriteLine("选项1被点击");
    }));

    actionSheet.AddAction(UIAlertAction.Create("选项2", UIAlertActionStyle.Default, (action) =>
    {
        // 选项2的点击事件处理
        Console.WriteLine("选项2被点击");
    }));

    actionSheet.AddAction(UIAlertAction.Create("取消", UIAlertActionStyle.Cancel, null));

    // 显示ActionSheet
    PresentViewController(actionSheet, true, null);
}
