我正在使用Monotouch开发iPad应用程序。
以下是我的情景：
我创建了选项卡式基础应用程序。 例如家庭，管理，报告......等 主页选项卡是UIViewController。
我想在Home标签中找到三个部分： 例如类别（具有导航控件的表视图（因为我们在类别中有子类别而使用导航的原因）在类别表旁边，所选类别的项目（其他表格视图）和右侧是所选项目的详细视图。
这就是我做的......
动态创建两个tableview控制器并添加到主视图控制器。
HomeViewController.cs：
public override void ViewDidLoad ()
{
base.ViewDidLoad ();
RootViewController rvc = new RootViewController("",UITableViewStyle.Grouped);
// navigation controller will manage the views displayed and provide navigation buttons
navigationController = new UINavigationController();
navigationController.PushViewController(rvc, false);
navigationController.TopViewController.Title ="Category";
navigationController.View.Frame = new RectangleF (0, 50, (50), (600));
// Main window to which we add the navigation controller to
this.View.AddSubview(navigationController.View);
itemtable.Delegate = new TableViewDelegate (list);
itemtable.DataSource = new TableViewDataSource (list);
// Perform any additional setup after loading the view, typically from a nib.
}

我不完全确定你想做什么。我采取了最好的猜测，并用两种解决方案创建了一个样本。每个标签一个解决方案第一个使用内置的拆分视图控制器。我已经阅读了几个地方，UISplitViewController必须是应用程序的根。我通过将其添加为制表符控件的子项来打破该规则。
第二个创建分割控件的自定义版本。
