架构x86_64的重复符号

Question

在使用Core plot API和ESRI map Arc GIS API时,我遇到了重复的符号问题.在我的应用程序中,我使用的是Core plot和ArcGIS API.为了提供对64位设备的支持,我已经为ArcGI(ESRI map)下载了新的API,并因此更新了64位的CorePlot API.在进行更改后,我面临的问题是:

错误描述在这里:

duplicate symbol _squareOfDistanceBetweenPoints in:
    /Users/xxxx/Library/SDKs/ArcGIS/iOS/ArcGIS.framework/ArcGIS(AGSCPTUtilities.o)
    /Users/xxxx/Desktop/18 Nov/SCM_iPad/SCM/CorePlot/coreplot_new.a(CPTUtilities.o)

ld: 5 duplicate symbols for architecture x86_64

如果有人面临问题请建议.我无法弄清楚这些API中有什么重复这些两个工作正常(没有64位支持的OLD api)

您可能已导入.m而不是.h文件
