看看Header Search Paths 为
'/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk/usr/include/libxml2'
看看Base SDK 为 ios 6.1
于是把Header Search Paths 该为
'/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk/usr/include/libxml2'
问题解决,但是有一个问题,如果这样做的话每升级一次版本就要修改一次。
正确做法因该是Header Search Paths 该为 ${SDKROOT}/usr/include/libxml2
