看来我们可以——理论上——构建一个包含模拟器和 iPhone 和 iPad 的静态库。
但是,Apple 没有我能找到的这方面的文档,并且 Xcode 的默认模板未配置为执行此操作。
我正在寻找一种可以在 Xcode 中完成的简单、可移植、可重用的技术。
一些历史:
参考:
这是一个好主意,这是一个很好的方法,但它不起作用:http ://www.drobnik.com/touch/2010/04/universal-static-libraries/
另一个 SO 提问者询问如何在没有 xcode 的情况下做到这一点,并且回答集中在 arm6 与 arm7 部分 - 但忽略了 i386 部分:我如何为 armv6、armv7 和 i386 编译静态库(fat)
由于 Apple 的最新更改,模拟器部分不再与 arm6/arm7 的差异相同 - 这是一个不同的问题,见上文)
备择方案:
轻松复制/粘贴最新版本(但安装说明可能会更改 - 见下文!)
Karl的库需要更多的精力来设置,但更好的长期解决方案(它将您的库转换为框架)。
使用它,然后对其进行调整以添加对存档构建的支持- 参见下面@Frederik的评论,关于他用来使其与存档模式很好地配合使用的更改。
iOS 10 更新:
我在使用 iphoneos10.0 构建 fatlib 时遇到了问题,因为脚本中的正则表达式只需要 9.x 和更低版本,并且为 ios 10.0 返回 0.0
解决这个问题只需更换
SDK_VERSION=$(echo ${SDK_NAME} | grep -o '.\{3\}$')
和
SDK_VERSION=$(echo ${SDK_NAME} | grep -o '[\\.0-9]\{3,4\}$')
最近的变化: 1. 增加了对 iOS 10.x 的支持(同时保持对旧平台的支持)
有关如何将此脚本与项目嵌入在另一个项目中的信息(尽管我强烈建议不要这样做,如果您将项目相互嵌入,Apple 在 Xcode 中有几个显示停止器错误,来自 Xcode 3.x 到 Xcode 4.6.x)
奖励脚本,让您自动包含捆绑包(即从您的库中包含 PNG 文件、PLIST 文件等!) - 见下文(滚动到底部)
现在支持 iPhone5(使用 Apple 的解决方法来解决 lipo 中的错误)。注意:安装说明已更改(我可能会通过更改脚本来简化此操作,但现在不想冒险)
“复制标头”部分现在尊重公共标头位置的构建设置(由 Frederik Wallner 提供)
添加了 SYMROOT 的显式设置(也许也需要设置 OBJROOT?),感谢 Doug Dickinson
脚本(这是您必须复制/粘贴的内容)
有关使用/安装说明,请参见下文

安装说明
…奖金可选用途:
如果找不到输出文件,这里有一个解决方法:
将以下代码添加到脚本的最后(由 Frederik Wallner 提供): open “${CREATING_UNIVERSAL_DIR}”
Apple 删除 200 行之后的所有输出。选择您的目标,在运行脚本阶段,您必须取消勾选:“在构建日志中显示环境变量”
如果您使用 XCode4 的自定义“构建输出”目录,那么 XCode 会将所有“意外”文件放在错误的位置。
…那是您的 Universal Build 的位置。
如何在项目中包含“非源代码”文件(PNG、PLIST、XML 等)
将构建的包自动复制到与 FAT 静态库相同的文件夹中的脚本:
echo "RunScript2:" echo "Autocopying any bundles into the 'universal' output folder created by RunScript1" CREATING_UNIVERSAL_DIR=${SYMROOT}/${CONFIGURATION}-universal cp -r "${BUILT_PRODUCTS_DIR}/"*.bundle "${CREATING_UNIVERSAL_DIR}"
