xcodebuild 使用注意事项

##1.xcodebuild cocoapod CONFIGURATION_BUILD_DIR ###现象 ``` bash xcodebuild命令用法示例 xcodebuild -sdk iphoneos -configuration ${BUILD_CONFIGURATION} -derivedDataPath=”../build” -workspace ‘../SohuInk.xcworkspace’ -scheme ‘SohuInk_Jenkins’ -archivePath “../SohuInk_Jenkins.xcarchive” archive

如果项目中使用了cocoapod并且xcodebuild 命令参数中指定了CONFIGURATION_BUILD_DIR并且值为相对路径,此时在Xcode Tools Version 5.0下的xcodebuild构建会报如下错误:  

``` bash error_info
ld: warning: directory not found for option '-L/XXXX/XXXX/pop'
ld: library not found for -lAFNetworking
clang: error: linker command failed with exit code 1 (use -v to see invocation)

** ARCHIVE FAILED **

The following build commands failed:
	Ld /Users/XXXX/XXXX/Objects-normal/arm64/SohuInk normal arm64
	Ld /Users/XXXX/XXXX normal armv7
(2 failures)

###解决方案
####方案1,不好用
Xcode Tools version 5.0 支持参数 derivedDataPath 可以放弃CONFIGURATION_BUILD_DIR配置指定该参数,我实际操作是发现使用相对路径的情况下,虽然可以archive success,但是build的目录没有改变,依然在xcode默认的derivedData目录下.
####方案2,OK CONFIGURATION_BUILD_DIR的值指定为绝对路径,一切OK,可成功archive. ###结论

xcodebuild中的CONFIGURATION_BUILD_DIR值需要使用绝对路径
