制作多架构iOS和Mac OS框架 [英] Making Multi-Architecture iOS and Mac OS Frameworks

问题描述

我在使用新的Xcode 6动态框架目标开发框架时遇到了问题。

基本上，我需要与旧方法相同的结果（在本教程中解释得非常好）。

我试过这个，但问题是只有框架生成几个ARM二进制文件。我还需要有i386 / x86_64二进制文件，所以它将是一个完整的框架。

我确定我忽略了一些东西。有没有人对这个无能为力的人有线索？

解决方案

是的，对大多数人来说这看起来并不是很有趣。 / p>

啊，好吧。我确实得到了更好的版本的Wenderlich脚本，我将在这里发布。

这具有作为头等公民框架的显着优势;不是由新目标生成的仅限iOS8的动态版本。

＃这个脚本将为$ FRAMEWORK_PRODUCT_NAME环境变量引用的项目构建多平台框架。 
＃此变量需要在此目标的构建设置中设置为用户定义的值（仅运行此脚本的聚合目标）。 
＃项目必须有一个静态lib目标，其名称由$ FRAMEWORK_PRODUCT_NAME定义，并且该目标的输出必须是
＃静态库，即lib $ {FRAMEWORK_PRODUCT_NAME} .a 。静态lib目标需要具有Debug和Release配置，其中
＃debug配置嵌入符号/分析信息（而不是单独的DSYM文件）。 
＃在任一配置中都不应对非调试进行剥离（但建议在Release中剥离调试符号）。 
＃聚合目标还应定义$ DELIVERABLE_DIRECTORY环境变量。这是从$ {BUILD_DIR} 
＃位置到用户想要传递框架的位置的相对POSIX路径。该脚本将在那里创建一个Framework目录，其中包含Debug和
＃Release目录;每个都包含框架的副本。 
＃静态lib目标需要创建一个带有导出头的Headers目录和一个Resources目录（即使它是空的）。

＃如果我们已经在这个脚本中，那么如果[-n$ MULTIPLATFORM_BUILD_IN_PROGRESS]则死掉

I'm having issues developing a Framework with the new Xcode 6 Dynamic Framework target.

Basically, I need the same result as the old way (Explained very well in this tutorial).

I tried this, but the problem is that the framework only produces a couple of ARM binaries. I need to have the i386/x86_64 binaries in there, as well, so it will be a complete framework.

I'm sure I'm overlooking something. Does anyone have a clue for this clueless person?

解决方案

Yeah, looks like this isn't very interesting to most folks.

Ah, well. I did get it going with a better version of the Wenderlich script, which I'll post here.

This has the significant advantage of being a "First Class Citizen" framework; not the iOS8-only dynamic version produced by the new target.

#! /bin/sh

# This was cribbed from here: http://www.raywenderlich.com/65964/create-a-framework-for-ios

# This script will build a multiplatform framework for the project referenced from the $FRAMEWORK_PRODUCT_NAME environment variable.
# This variable needs to be set as a user-defined value in the build settings of this target (an aggregate target that just runs this script).
# The project must have a static lib target, with the exact name defined by $FRAMEWORK_PRODUCT_NAME, and the output from that target needs to be
# a static lib that is "lib${FRAMEWORK_PRODUCT_NAME}.a". The static lib target needs to have a "Debug" and a "Release" configuration, with the
# debug configuration embedding symbols/profiling information (as opposed to a separate DSYM file).
# No stripping should be done for non-debug in either configuration (but it is advised to strip debug symbols in "Release").
# The aggregate target should also define the $DELIVERABLE_DIRECTORY environment variable. This is a relative POSIX path from the ${BUILD_DIR}
# location, to a place that the user wants to deliver the framework. The script will create a "Framework" directory there, with a "Debug" and
# a "Release" directory; each containing a copy of the framework.
# The static lib target needs to create a "Headers" directory with exported headers, and a "Resources" directory (even if it is empty).

set -e

# If we're already inside this script then die
if [ -n "$MULTIPLATFORM_BUILD_IN_PROGRESS" ]; then
    exit 0
fi
export MULTIPLATFORM_BUILD_IN_PROGRESS=1

# This function actually runs the static lib target build, in the configuration requested.
# INPUT: SDK, configuration (either "Debug" or "Release"), target name

}

# This function will build the iphoneos and iphonesimulator versions of the framework, and will
# use lipo to merge them together into a "fat" binary that contains x86 and ARM code.
# It will also copy the headers and the resources for the framework, so the static lib target needs to create
# a "Headers" directory with exported headers, and a "Resources" directory (even if it is empty).
