@Ckouta 感谢您的快速回复。我提到了那个链接，它没有解决我的问题。

【参考方案1】：

为您的项目添加新的核心绘图库框架。删除旧库。这些是要遵循的步骤

下载核心绘图库。 打开 xcode CorePlot-CocoaTouch.xcodeproj 进入项目并点击构建 现在转到您的 mac 中的核心绘图框架文件夹。您可以在其中看到 build 文件夹。 现在打开终端并提供您的核心绘图路径 cd CorePlot_1.4/Source/build/ 类型 lipo -create ./Debug-iphoneos/libCorePlot-CocoaTouch.a ./Debug-iphonesimulator/libCorePlot-CocoaTouch.a -output core_plot_all.a 已创建新库，现在将此库和核心头文件添加到您的项目中。 现在构建您的项目。

然后将 -ObjC 添加到其他链接器标志
