前段时间谷歌发布了j2objc工具（java代码转换成objective-c工具），我把工具的使用方法写在这上面
J2objc的使用
< h2 style="margin: 0px; padding: 0px; color: rgb(73, 73, 73); font-family: Arial, Helvetica, sans-serif; font-style: normal; font-variant: normal; letter-spacing: normal; orphans: 2; text-align: -webkit-auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; ">1 要求：
< p style="margin: 10px auto; padding: 0px; text-indent: 0px; color: rgb(73, 73, 73); font-family: Arial, Helvetica, sans-serif; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: 22px; orphans: 2; text-align: -webkit-auto; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; ">
Xcode 4
or higher< p style="margin: 10px auto; padding: 0px; text-indent: 0px; color: rgb(73, 73, 73); font-family: Arial, Helvetica, sans-serif; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: 22px; orphans: 2; text-align: -webkit-auto; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; ">
Java for OS X
（JDK1.6）< p style="margin: 10px auto; padding: 0px; text-indent: 0px; color: rgb(73, 73, 73); font-family: Arial, Helvetica, sans-serif; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: 22px; orphans: 2; text-align: -webkit-auto; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; ">
Apache Maven
（可有可无，根据使用j2objc的方式）< h2 style="margin: 0px; padding: 0px; color: rgb(73, 73, 73); font-family: Arial, Helvetica, sans-serif; font-style: normal; font-variant: normal; letter-spacing: normal; orphans: 2; text-align: -webkit-auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; ">2 使用方式及步骤
< h3 style="margin: 0px; padding: 0px; color: rgb(73, 73, 73); font-family: Arial, Helvetica, sans-serif; font-style: normal; font-variant: normal; letter-spacing: normal; orphans: 2; text-align: -webkit-auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; ">2.1 使用方式
< p style="margin: 10px auto; padding: 0px; text-indent: 0px; color: rgb(73, 73, 73); font-family: Arial, Helvetica, sans-serif; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: 22px; orphans: 2; text-align: -webkit-auto; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; ">在xcode中使用j2objc有两种方式：第一种是在外部构建工程作为一个独立的生成文件。第二种是为xcode工程类型添加规则。外部构建工程的的优点是仍然可以使用现有的java工具，如IDE支持错误的检查的重构。建立规则的优点是java源作为xcode工程中的一部分，且java源很快可以在调试时使用。< h3 style="margin: 0px; padding: 0px; color: rgb(73, 73, 73); font-family: Arial, Helvetica, sans-serif; font-style: normal; font-variant: normal; letter-spacing: normal; orphans: 2; text-align: -webkit-auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; ">2.2 使用步骤
< p style="margin: 10px auto; padding: 0px; text-indent: 0px; color: rgb(73, 73, 73); font-family: Arial, Helvetica, sans-serif; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: 22px; orphans: 2; text-align: -webkit-auto; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; ">以xcode工程添加规则的使用方式为例：
< ol style="margin: 0px; padding: 0px 0px 0px 50px; color: rgb(73, 73, 73); font-family: Arial, Helvetica, sans-serif; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: 22px; orphans: 2; text-align: -webkit-auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; ">
先下载安装Xcode工具以及 javaforOSX。
下载解压 j2objc 0.5.3。
在Xcode中配置规则：如下
