问题描述
我在项目中加入了Apple KML Viewer的类KMLParser.m.我遇到的问题是，当我尝试构建项目时遇到了两个错误:
I have included the class KMLParser.m of Apple's KML Viewer in my project.The problem that I have is that when I try to build the project i get two errors like these:
_CLLocationCoordinate2DMake，引用自:KMLParser.o中的_strToCoords
_CLLocationCoordinate2DMake,referenced from:_strToCoords in KMLParser.o
_CLLocationCoordinate2DisValid，引用自:KMLParser.m
我不知道为什么会发生此错误，因为我保留了文件KMLParser.m和KMLParser.h完整无缺，因此我没有对其进行任何更改.构建KML Viewer时，一切都很好.请照亮我.
I don't have any idea why this error occurs, because i have left the files KMLParser.m and KMLParser.h intact, I haven't made any change to them.When I build KML Viewer, everything is fine. Please,illuminate me.
推荐答案
您需要向项目中添加Core Location框架(仅#import是不够的).
You need to add the Core Location framework to your project (an #import alone is not enough).
对于Xcode 3.x，右键单击项目文件，然后转到添加-现有框架".
For Xcode 3.x, right-click on the project file and go to Add - Existing Frameworks.
对于Xcode 4.x，请参见如何添加现有内容"框架"在Xcode 4中?.
For Xcode 4.x, see How to "add existing frameworks" in Xcode 4?.
