使用Xcode和SDK 4+构建胖静态库(设备+模拟器)
看起来,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没有关于此的文档,我可以找到它,而Xcode的默认模板未配置为执行此操作。
我正在寻找一种简单,便携,可重复使用的技术,可以在Xcode中完成。
有些历史:
参考文献:
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提问者询问了如何在没有xcode的情况下做到这一点,以及关注arm6 vs arm7部分的回应 - 但忽略了i386部分:我如何为armv6,armv7和i386编译一个静态库(fat)
备择方案:
轻松复制/粘贴最新版本(但安装说明可能会更改 - 请参阅下文!)
Karl的库需要更多的努力来设置,但更好的长期解决方案(它将您的库转换为框架)。
使用它,然后调整它以添加对存档构建的支持 - cf @ Frederik对他正在使用的更改进行评论,以使其与存档模式很好地配合使用。
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)
关于如何将这个脚本与项目嵌入到另一个项目中使用的信息(尽管我强烈建议不要那么做 - 如果你在Xcode中相互嵌入项目的话,苹果在Xcode中会遇到一些显示停止的bug 3.x到Xcode 4.6.x)
Bonus脚本让你自动包含Bundles(即包括PNG文件,PLIST文件等等) - 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(我可能通过将来更改脚本来简化此操作,但现在不想冒险)
“复制标题”部分现在考虑公共标题位置的构建设置(由Frederik Wallner提供)
感谢Doug Dickinson,增加了SYMROOT的显式设置(可能需要设置OBJROOT?)
脚本(这是你必须复制/粘贴)

# Version 2.82
#
# Latest Change:
# - MORE tweaks to get the iOS 10+ and 9- working
# - Support iOS 10+
# - Corrected typo for iOS 1-10+ (thanks @stuikomma)
#
# Purpose:
# Automatically create a Universal static library for iPhone + iPad + iPhone Simulator from within XCode

# Author: Adam Martin - http://twitter.com/redglassesapps
# Based on: original script from Eonil (main changes: Eonil's script WILL NOT WORK in Xcode GUI - it WILL CRASH YOUR COMPUTER)

安装说明
...奖金可选用法:
如果你找不到输出文件,这是一个解决方法:
将以下代码添加到脚本的最后(由Frederik Wallner提供):打开“$ {CREATING_UNIVERSAL_DIR}”
Apple在200行后删除所有输出。 选择你的目标,并在运行脚本阶段,你必须取消:“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,则XCode会将所有“意外”文件放在错误的位置。
...这是您的Universal Build的位置。
如何在项目中包含“非源代码”文件(PNG,PLIST,XML等)
脚本自动将构建的软件包复制到FAT静态库所在的文件夹中:
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}"
我花了很多时间试图建立一个可以在armv7,armv7s和模拟器上工作的胖静态库。 终于找到了解决办法。
要点是分别建立两个库(一个用于设备,另一个用于模拟器),重命名它们以区别对方,然后将lipo - 创建为一个库。
lipo -create libPhone.a libSimulator.a -output libUniversal.a
我试了一下,它的工作原理!
我制作了一个XCode 4项目模板,可以让您像制作常规库一样轻松制作通用框架。
