用CorePlot编译项目问题

Question

今天我试着用CorePlot编译一个项目。

所有的时间，我得到了以下错误：

".objc_class_name_NSNotificationCenter", referenced from: 
literal-pointer@__OBJC@__cls_refs@NSNotificationCenter in libCorePlot.a(CPGraph.o) 
literal-pointer@__OBJC@__cls_refs@NSNotificationCenter in libCorePlot.a(CPXYPlotSpace.o)

literal-pointer@__OBJC@__cls_refs@NSMutableArray in libCorePlot.a(CPScatterPlot.o) 
literal-pointer@__OBJC@__cls_refs@NSMutableArray in libCorePlot.a(CPBarPlot.o)  [ . . . ] 

我希望有人能帮助我。

编辑：它的工作，如果我尝试编译设备，但不适合模拟器。

Answer 1

通过在projectsettings中设置标题搜索路径，我错过了包括框架的头文件。 =>双击目标=>画报=>搜索头搜索路径设定值：recursiv = YES搜索和../framework/

它应该是这样的：

下载框架这里：http://code.google.com/p/core-plot/downloads/detail?name=alpharelease_0.1.zip&can=2&q=

复制框架毗邻项目的文件夹中的文件夹。

我似乎已经解决了我早些时候遇到的问题，但我最好猜测它只能通过添加其余代码来修复，它可能仍然隐藏在这7个其他错误的后面。我已经附加完整的视图controller.m文件更有经验的眼睛。
