制作多架构 iOS 和 Mac OS 框架

Question

我在使用新的 Xcode 6 动态框架目标开发框架时遇到问题。

基本上，我需要与旧方法相同的结果 (Explained very well in this tutorial)。

我尝试了this，但问题是该框架只生成了几个 ARM 二进制文件。我还需要在其中包含 i386/x86_64 二进制文件，因此它将是一个完整的框架。

我确定我忽略了一些东西。有人知道这个无知的人吗？

是的，看起来这对大多数人来说不是很有趣。

啊，好吧。我确实使用了更好的 Wenderlich 脚本版本，我将在此处发布。

这具有成为“一等公民”框架的显着优势；不是新目标生成的仅限 iOS8 的动态版本。

#! /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).
