C# Monotouch：通过编程方式使用动态视图控制器创建UITabbar
我尝试了很多方法，在网上搜索都没有成功。以下是我尝试过但无法运行的最简单方法： 如果我运行此代码，它将正确显示选项卡栏，但当我单击选项卡时，我会得到一个异常，我将其粘贴在下面的代码示例下 这是my MainMenu.cs中的一个方法，它是条目xib 我很感激你对我的帮助。提前非常感谢C# Monotouch：通过编程方式使用动态视图控制器创建UITabbar,c#,mono,xamarin.ios,uitabbar,C#,Mono,Xamarin.ios,Uitabbar,我尝试了很多方法，在网上搜索都没有成功。以下是我尝试过但无法运行的最简单方法： 如果我运行此代码，它将正确显示选项卡栏，但当我单击选项卡时，我会得到一个异常，我将其粘贴在下面的代码示例下 这是my MainMenu.cs中的一个方法，它是条目xib 我很感激你对我的帮助。提前非常感谢 private void Render_Screen (object sender, RenderScreenEventArgs e) { UITabBarController tabbar
