This page (in the comments section) may help you with that: http://code.google.com/p/core-plot/wiki/UsingCorePlotInApplications

这是以前的堆栈溢出问题，看起来像您一样：

And this is a previous Stack Overflow question that looks like yours: Using Core Plot iPhone - Linker error

有一些我在上面的页面中找到的修复程序：

Here are some fixes I found on the pages above:

• 在CorePlot-CocoaTouch项目设置中，更改 iOS部署目标 到 3.2
  
  
  
  
  • 将所有配置的 仅将活动架构构建 更改为否
  
  
  • 更改 C / C ++编译器版本 从GCC 4.2到 LLVM GCC 4.2
  
  
  • In CorePlot-CocoaTouch project settings, change iOS Deployment Target to 3.2
    • change Build Active Architecture Only to No for all configurations
    • change C/C++ Compiler Version from GCC 4.2 to LLVM GCC 4.2
