导入“SOTC_CorePlotViewController.h”

Question

今天我尝试使用CorePlot编译项目。

我一直遇到以下错误：

  ".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(CPBarPlot.o)      [ . . . ]

我希望有人可以帮助我。

编辑：如果我尝试编译设备而不是模拟器，它会工作。

Answer 1

通过在projectsettings中设置标题搜索路径，我错过了包含框架的头文件。 =＆GT;双击Target =＆gt; bild =＆gt;搜索标题搜索路径将值设置为： recursiv = YES 搜索和 ../ framework /

应该如下所示： alt text

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

复制项目文件夹旁边的框架文件夹。

我似乎已经解决了我之前遇到的问题，但我最好的猜测只是通过添加其余的代码来修复，它可能仍然隐藏在这7个其他错误背后。我已经附上了完整的视图controller.m文件，供更有经验的人使用。
