c# - Xamarin Monotouch UISplitViewController : How can I set or create the delegate for UISplitViewController?

Question

我有一个 UISplitViewController，并尝试从 MasterViewController 获取事件并完全更改 DetailViewController。据我了解，这基本上可以通过执行以下操作来完成:

ViewControllers[1] = new MyNewViewController();

当我这样做时，什么都没有改变!我知道这与设置委托(delegate)有关，但我不知道在哪里以及如何执行此操作。

Answer 1

重写 UISplitViewControllerDelegate 来执行任何需要执行的操作。我的一个应用程序的示例:

using System;

using MonoTouch.UIKit;

namespace PythonMath
{
    class SplitViewControllerDelegate : UISplitViewControllerDelegate
    {
        public override bool ShouldHideViewController(
            UISplitViewController svc,
            UIViewController viewController,
            UIInterfaceOrientation inOrientation)
        {
            return (! InAppPurchaseModel.Editor.Purchased) ||
                inOrientation == UIInterfaceOrientation.Portrait ||
                inOrientation == UIInterfaceOrientation.PortraitUpsideDown;
        }
    }
}

然后将其分配给 UISplitViewController 的委托(delegate):

var SplitViewController = new UISplitViewController();
SplitViewController.Delegate = new SplitViewControllerDelegate ();
