phonegap及libCordova.a编译问题

libCordova.a编译问题可以分为两种：

一种错误是提示：
error: no such file or directory: '/Users/xxxx/Library/Developer/Xcode/DerivedData/FirstProject-ctanrqwggcfoubbeqbjrfvcqozpg/Build/Products/Debug-iphoneos/libCordova.a'。
可以通过修改CordovaLib.xcodeproj和xxxx.xcodeproj工程的的“Build Active Architecture Only”选项来解决，将选项从NO改为YES;
第二种错误是提示：（archive或真机调试）
file not found: /Users/xxxx/Library/Developer/Xcode/DerivedData/xxxx-gylybvwifdxjmtajtbvdsdpjcvkl/Build/Intermediates/ArchiveIntermediates/xxxx/InstallationBuildProductsLocation/Applications/libCordova.a
error: linker command failed with exit code 1 (use -v to see invocation)
解决办法是
Target's Build Settings-> Other Linker Flags
将 $(TARGET_BUILD_DIR)/libCordova.a 修改为 $(BUILT_PRODUCTS_DIR)/libCordova.a
