iOS构建framework

原因：同种业务需要在不同的客户端项目中使用。

问题：

1.代码只能存在一个项目中，便于维护。

2.对业务依赖很大

几种构建的方式

1. 选择pod构建私有库的形式(略)

pod lib create ""

配置等东西自行查找

注意：在podfile里面有一个use_frameworks! 注释掉，这个选项会使生成的结构变成在[nsbundle mainbundle]/framework/xxx.framework/xxx.bundle，导致一般使用xxx.bundle/xxx.png找不到路径

配置s.subspec的时候，如果里面的文件依赖了什么，都需要s.dependency,所以，如果不是依赖关系很大的可以使用，这样会使文件结构很清晰

2. 选择library和bundle构建形式

1.创建static library

new->project->framework & library -> 任选 一个包含uikit，一个包含foundation，可后面引入
在这个target的build phases加入一个run script phases，然后加入如下代码，目的：使输出的frame拥有如下结构：

image

set -e

export FRAMEWORK_LOCN="${BUILT_PRODUCTS_DIR}/${PRODUCT_NAME}.framework"

# Create the path to the real Headers die
mkdir -p "${FRAMEWORK_LOCN}/Versions/A/Headers"

# Create the required symlinks
/bin/ln -sfh A "${FRAMEWORK_LOCN}/Versions/Current"
/bin/ln -sfh Versions/Current/Headers "${FRAMEWORK_LOCN}/Headers"
/bin/ln -sfh "Versions/Current/${PRODUCT_NAME}" \
"${FRAMEWORK_LOCN}/${PRODUCT_NAME}"

# Copy the public headers into the framework
/bin/cp -a "${TARGET_BUILD_DIR}/${PUBLIC_HEADERS_FOLDER_PATH}/" \
"${FRAMEWORK_LOCN}/Versions/A/Headers"

2.创建一个能生成bundle的target

new->target-> OS X->framework & library -> bundle

选择这个target，然后在buildsettings里面，找到baseSDK删除，会出现变成iOS的版本

加入图片等资源是，在选择的时候选择options，勾选这个bundle的target

3.创建一个管理上面bundle和frame的target

new->target->other->Aggregate
选择此target->build phases. 在target dependencies里面添加依赖的其他两个target
在这里我们需要导出.framework和.bundle，并且需要对不同平台进行编译
创建run script,添加如下代码

set -e

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

RW_FRAMEWORK_NAME=${PROJECT_NAME}
RW_INPUT_STATIC_LIB="lib${PROJECT_NAME}.a"
RW_FRAMEWORK_LOCATION="${BUILT_PRODUCTS_DIR}/${RW_FRAMEWORK_NAME}.framework"

function build_static_library {
    # Will rebuild the static library as specified
    #     build_static_library sdk
    xcrun xcodebuild -project "${PROJECT_FILE_PATH}" \
    -target "${TARGET_NAME}" \
    -configuration "${CONFIGURATION}" \
    -sdk "${1}" \
    ONLY_ACTIVE_ARCH=NO \
    BUILD_DIR="${BUILD_DIR}" \
    OBJROOT="${OBJROOT}" \
    BUILD_ROOT="${BUILD_ROOT}" \
    SYMROOT="${SYMROOT}" $ACTION
}

function make_fat_library {
    # Will smash 2 static libs together
    #     make_fat_library in1 in2 out
    xcrun lipo -create "${1}" "${2}" -output "${3}"
}

# 1 - Extract the platform (iphoneos/iphonesimulator) from the SDK name
if [[ "$SDK_NAME" =~ ([A-Za-z]+) ]]; then
RW_SDK_PLATFORM=${BASH_REMATCH[1]}
else
echo "Could not find platform name from SDK_NAME: $SDK_NAME"
exit 1
fi

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

# 3 - Determine the other platform
if [ "$RW_SDK_PLATFORM" == "iphoneos" ]; then
RW_OTHER_PLATFORM=iphonesimulator
else
RW_OTHER_PLATFORM=iphoneos
fi

# 4 - Find the build directory
if [[ "$BUILT_PRODUCTS_DIR" =~ (.*)$RW_SDK_PLATFORM$ ]]; then
RW_OTHER_BUILT_PRODUCTS_DIR="${BASH_REMATCH[1]}${RW_OTHER_PLATFORM}"
else
echo "Could not find other platform build directory."
exit 1
fi

# Build the other platform.
build_static_library "${RW_OTHER_PLATFORM}${RW_SDK_VERSION}"

# If we're currently building for iphonesimulator, then need to rebuild
#   to ensure that we get both i386 and x86_64
if [ "$RW_SDK_PLATFORM" == "iphonesimulator" ]; then
build_static_library "${SDK_NAME}"
fi

# Join the 2 static libs into 1 and push into the .framework
make_fat_library "${BUILT_PRODUCTS_DIR}/${RW_INPUT_STATIC_LIB}" \
"${RW_OTHER_BUILT_PRODUCTS_DIR}/${RW_INPUT_STATIC_LIB}" \
"${RW_FRAMEWORK_LOCATION}/Versions/A/${RW_FRAMEWORK_NAME}"

# Ensure that the framework is present in both platform's build directories
cp -a "${RW_FRAMEWORK_LOCATION}/Versions/A/${RW_FRAMEWORK_NAME}" \
"${RW_OTHER_BUILT_PRODUCTS_DIR}/${RW_FRAMEWORK_NAME}.framework/Versions/A/${RW_FRAMEWORK_NAME}"

# Copy the framework to the user's desktop
ditto "${RW_FRAMEWORK_LOCATION}" "${HOME}${PROJECT_AUCTION_DIR}/${RW_FRAMEWORK_NAME}.framework"
ditto "${BUILT_PRODUCTS_DIR}/${RW_FRAMEWORK_NAME}.bundle" \
"${HOME}${PROJECT_AUCTION_DIR}/${RW_FRAMEWORK_NAME}.bundle"
