CorePlot - 未找到CPTAnnotation.h [英] CorePlot - CPTAnnotation.h not found

问题描述

我正在尝试使用 CorePlot 绘制一个简单的情节。

I'm trying to use CorePlot to draw a simple plot.

我正在使用本教程，但是当我在 ViewController.h中输入：

I'm working from this tutorial, but when I type this in my ViewController.h:

<CPPlotDataSource>
{
   CPXYGraph *graph;
}    

我遇到错误： CPTAnnotation.h文件没有发现

可能是什么原因？

推荐答案

自编写该教程以来，Core Plot类前缀已从CP更改为CPT。如果您在Core Plot 0.3之后使用任何内容，则还需要对代码进行更改。该帖子的评论中还讨论了其他一些必要的更改。

The Core Plot class prefix has changed from "CP" to "CPT" since that tutorial was written. If you're using anything later than Core Plot 0.3, you'll need to make the change in your code, too. There are several other needed changes that are discussed in the comments on that post.
