我正在尝试使用以下代码为我的自定义视图的移动设置动画（我最好的翻译来自苹果自己的文档的objective-c）

        var animDict = new NSMutableDictionary ();
        animDict [NSViewAnimation.TargetKey] = this.View;
        animDict [NSViewAnimation.StartFrameKey] = NSValue.FromRectangleF (this.View.Frame);
        animDict [NSViewAnimation.EndFrameKey] = NSValue.FromRectangleF (new RectangleF (0, 150 * index, 400, 150));

        var theAnim = new NSViewAnimation ();
        theAnim.SetValuesForKeysWithDictionary (animDict);
        theAnim.Duration = 2;
        theAnim.StartAnimation ();

但是，在运行应用程序时出现以下运行时错误： 2011-05-08 00:53:30.827 EpisodeNext[61715:613] [ setValue:forUndefinedKey:]: 此类与键 NSViewAnimationTargetKey 的键值编码不兼容.

知道我做错了什么吗？谢谢！

您不能使用该方法SetValuesForKeysWithDictionary将动画键传递给NSViewAnimation实例。

您必须使用NSViewAnimation(NSDictionary[] viewAnimations)构造函数来传递动画字典。

// 为第一个视图创建属性字典。

        NSMutableDictionary firstViewDict = new NSMutableDictionary ();


        //var firstViewRect = new NSDictionary[] { };
        firstViewDict [NSViewAnimation.TargetKey] = animateWindow;
        firstViewDict [NSViewAnimation.StartFrameKey] = NSValue.FromRectangleF (new RectangleF (1000, 300 , this.Frame.Width - 40, 0));
        firstViewDict [NSViewAnimation.EndFrameKey]  = NSValue.FromRectangleF (SettingNSWindow.Frame);


        //var NSDict = new NSDictionary[]{ };
        NSDictionary[] NSDict =  new NSDictionary[]{firstViewDict};

        //NSDict.Cast(NSMutableDictionary = (NSDictionary[])firstViewDict;

        NSViewAnimation theAnim = new NSViewAnimation(NSDict);

        //theAnim.SetValuesForKeysWithDictionary (firstViewDict);
        theAnim.Duration = 2;
        theAnim.StartAnimation ();
