Xcode 4.1安装iOS 4.3 Library和Mac OS X Lion Library


系统环境：Lion正式版10.7.1(build 11B26)

Xcode 4.1.1 (build 4B110)

PS：Xcode 4.1和 4.1.1的区别在于安装界面，本身内容没有变化，build号4B110就是4.1.1的

在全新安装Lion之后，App Store下载安装了Xcode，发现并没有附带iOS和Mac OS X Lion的编程参考文档(Library)。

在Preferences-->Documentation中点击Check and Install Now

根据得到的版本号和feed地址，使用safari或者firefox打开页面选择最新的版本下载，解压缩到安装目录，如图中所示

然后要修改解压出来的docset所有者信息和文件属性

sudo chown -R -P _devdocs:wheel com.apple.adc.documentation.AppleLion.CoreReference.docset

sudo chmod 775 com.apple.adc.documentation.AppleLion.CoreReference.docset

sudo chown -R -P _devdocs:wheel com.apple.adc.documentation.AppleiOS4_3.iOSLibrary.docset

sudo chmod 775 com.apple.adc.documentation.AppleiOS4_3.iOSLibrary.docset

然后重新启动Xcode，就能查看文档了
