ios framework 开发 之 实战 一，合并失败了

保证public 文件目录独立

在 XCode 7 中，这一条已经自动实现了

Build Settings》Public Headers Folder Path

"$(PROJECT_NAME)Headers" for all configurations

避免代码、调试符号等被剥离

在 Build Setting 中设置

"Dead Code Stripping" => No (for all settings)
"Strip Debug Symbols During Copy" => No (for all settings)//XCode7中，默认就是这样
"Strip Style" => Non-Global Symbols (for all settings)

支持全平台的版本

在Project 中的 Build Setting 中设置

"Build Active Architecture Only" => No

分为debug 和 release 版本，debug的时候可以设置为Yes.

把Framework作为依赖对象

set -e

rm -rf "${BUILT_PRODUCTS_DIR}/${PRODUCT_NAME}.framework/Versions/A/Headers"
mkdir -p "${BUILT_PRODUCTS_DIR}/${PRODUCT_NAME}.framework/Versions/A/Headers"

# Link the "Current" version to "A"
/bin/ln -sfh A "${BUILT_PRODUCTS_DIR}/${PRODUCT_NAME}.framework/Versions/Current"
/bin/ln -sfh Versions/Current/Headers "${BUILT_PRODUCTS_DIR}/${PRODUCT_NAME}.framework/Headers"
/bin/ln -sfh "Versions/Current/${PRODUCT_NAME}" "${BUILT_PRODUCTS_DIR}/${PRODUCT_NAME}.framework/${PRODUCT_NAME}"

# The -a ensures that the headers maintain the source modification date so that we don't constantly
# cause propagating rebuilds of files that import these headers.
/bin/cp -a "${TARGET_BUILD_DIR}/${PUBLIC_HEADERS_FOLDER_PATH}/" "${BUILT_PRODUCTS_DIR}/${PRODUCT_NAME}.framework/Versions/A/Headers"

该步操作只会编译一个平台的版本，但是发布的时候，并不知道第三方会用手机，还是用模拟器来使用。所以下面需要编译一个“fat library”。

编译 fat framework

适配各个平台

Step 1 : Create an Aggregate Target

File > New Target > iOS > Other and create a new Aggregate target

Step 2 : Add the Static Library as a Dependent Target

在Target Dependencies中添加当前的framework

Step 3 : 在 fat framework中添加一个新的run script

set -e
set +u
# Avoid recursively calling this script.
if [[ $SF_MASTER_SCRIPT_RUNNING ]]
then
    exit 0
fi
set -u
export SF_MASTER_SCRIPT_RUNNING=1

SF_TARGET_NAME=${PROJECT_NAME}
SF_EXECUTABLE_PATH="lib${SF_TARGET_NAME}.a"
SF_WRAPPER_NAME="${SF_TARGET_NAME}.framework"

# The following conditionals come from
# https://github.com/kstenerud/iOS-Universal-Framework

if [[ "$SDK_NAME" =~ ([A-Za-z]+) ]]
then
    SF_SDK_PLATFORM=${BASH_REMATCH[1]}
else
    echo "Could not find platform name from SDK_NAME: $SDK_NAME"
    exit 1
fi

if [[ "$SDK_NAME" =~ ([0-9]+.*$) ]]
then
    SF_SDK_VERSION=${BASH_REMATCH[1]}
else
    echo "Could not find sdk version from SDK_NAME: $SDK_NAME"
    exit 1
fi

if [[ "$SF_SDK_PLATFORM" = "iphoneos" ]]
then
    SF_OTHER_PLATFORM=iphonesimulator
else
    SF_OTHER_PLATFORM=iphoneos
fi

if [[ "$BUILT_PRODUCTS_DIR" =~ (.*)$SF_SDK_PLATFORM$ ]]
then
    SF_OTHER_BUILT_PRODUCTS_DIR="${BASH_REMATCH[1]}${SF_OTHER_PLATFORM}"
else
    echo "Could not find platform name from build products directory: $BUILT_PRODUCTS_DIR"
    exit 1
fi

# Build the other platform.
xcrun xcodebuild -project "${PROJECT_FILE_PATH}" -target "${TARGET_NAME}" -configuration "${CONFIGURATION}" -sdk ${SF_OTHER_PLATFORM}${SF_SDK_VERSION} BUILD_DIR="${BUILD_DIR}" OBJROOT="${OBJROOT}" BUILD_ROOT="${BUILD_ROOT}" SYMROOT="${SYMROOT}" $ACTION

# Smash the two static libraries into one fat binary and store it in the .framework
xcrun lipo -create "${BUILT_PRODUCTS_DIR}/${SF_EXECUTABLE_PATH}" "${SF_OTHER_BUILT_PRODUCTS_DIR}/${SF_EXECUTABLE_PATH}" -output "${BUILT_PRODUCTS_DIR}/${SF_WRAPPER_NAME}/Versions/A/${SF_TARGET_NAME}"

# Copy the binary to the other architecture folder to have a complete framework in both.
cp -a "${BUILT_PRODUCTS_DIR}/${SF_WRAPPER_NAME}/Versions/A/${SF_TARGET_NAME}" "${SF_OTHER_BUILT_PRODUCTS_DIR}/${SF_WRAPPER_NAME}/Versions/A/${SF_TARGET_NAME}"

如果使用 Cocoapods ，就需要替换掉 xcrun xcodebuild 这行
