ios - CorePlot 在通用库上出错

Question

您好，我正在尝试在我的项目中为 armv7 和 arm64 位支持重建核心图。我以前的项目版本在 core-plot 上运行良好，但它是 32 位的。

为了支持 64 位，我所做的是从 here 下载 core-plot并在框架文件夹中打开 CorePlot-CocoaTouch.xcodeproj，将架构更改为 armv7 和 arm64 并将有效架构更改为 x86_64、i386、armv6 , armv7.

然后设置Product->Scheme->Universal Library并构建它。

现在我可以看到生成的库 build/Release-universal 名称为 libCorePlot-CocoaTouch.a 和 header 文件夹 CorePlotHeaders，我将这两个复制到我的项目(32 位库和 header 所在的相同位置)，

然后我收到以下错误。

Core Plot API 在 1.x 和 2.x 之间略有变化，以适应 Swift 中缺少 NSDecimal 支持并稍微简化它。看这个wiki page有关更改的详细信息。
