Core-Plot：在Interface Builder文件中的未知类CPLayerHostingView [英] Core-Plot: Unknown class CPLayerHostingView in Interface Builder file

问题描述

使用核心图似乎不是一个简单的集成任务。标题路径已设置。在Interface-Builder中，我创建一个 CPLayerHostingView ，属于View Controller，由Interface Builder实例化。

Using core-plot does not seem to be an easy integration task. Header path are already setup. In Interface-Builder I create an CPLayerHostingView which belongs to a View Controller which is instantiated by Interface Builder.

当加载nib文件时，我收到以下消息：

When the nib file is loaded I get the message:

Unknown class CPLayerHostingView in Interface Builder file

推荐答案

有两个不同的版本的对象。一个用于Mac的仅称为CPLayerHostingView，一个用于iPhone的仅称为CPGraphHostingView。

I found, that there are two different versions of that object. One for Mac-Only called "CPLayerHostingView", one for iPhone only called "CPGraphHostingView".

如果按照 http://www.switchonthecode.com/tutorials/using-core-plot-in-an-iphone-application 如果构建一个iPhone应用程序，你将使用以下行：

If following the poplular example at http://www.switchonthecode.com/tutorials/using-core-plot-in-an-iphone-application you would use the following lines, if building an iPhone-App:

CPGraphHostingView *graphView = (CPGraphHostingView*)self.view;
graphView.hostedGraph = graph;
