建立工程

File->New->project->Cocoa Touch Static Library

然後要求你輸入Product Name

Product Name 為你framework的名字，例如以後你的framework叫Example.framework，那麼Product Name 就叫 Example

工程設定

選中TARGETS 中的Example(小房子圖示)

切換到Build Settings，設定
- Dead Code Stripping -> NO
- Strip Debug Symbols During Copy -> NO
- Strip Style -> Non-Clobal Symbols

新增檔案

然後切換到 Build Phases，點一下選項卡中的空白處

然後選擇工具欄中的Editor->Add Build Phase->Add Copy Header Build Phase(如果是灰色的不能點選，那麼點一下 Build Phases選項卡中的空白處就出來了)

這時候Build Phases 中會出現Headers 下拉列表

將你需要的.h和.m檔案複製、新增到你的Framework工程

這時候你會發現Headers 中的Project 出現了你剛剛新增的.h檔案

將想暴露出來的.h檔案拉到Public

設定靜態庫指令碼

Editor->Add Build Phase -> Add Run Script Build Phase
(如果是灰色的不能點選，那麼點一下 Build Phases選項卡中的空白處就出來了)

雙擊標題Run Script ，重新命名為 Build Framework

然後在文字框中貼上以下指令碼

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"

建立Aggregate

選中TARGETS ,點選+號，找到iOS->Other->Aggregate，點選Next，將目標命名為Framework

選中Framework，展開Target Dependencies，點選+號，選中Example

切換到Build Pheses 選項卡，點選Editor->Add Build Phase->Add Run Script Build Phase，建立一個新的Run Script Build Phase。雙擊Run Script，重新命名指令碼的名字，這次命名為MultiPlatform Build，貼上Bash指令碼

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}/Desktop/${RW_FRAMEWORK_NAME}.framework"

編譯

選擇編譯目標 Example -> Generic iOS Device，鍵盤command+B 編譯

然後選擇編譯目標Framework -> Generic iOS Device，鍵盤command+B 編譯

切換到桌面看下，你要的framework 是不是躺在桌面等你了

驗證

驗證framework架構是否正確，開啟終端，cd到你的framework裡面，執行命令

xcrun lipo -info Example

輸出

Architectures in the fat file: Example are: armv7 i386 x86_64 arm64

恭喜您framework製作成功！

後記

如果有用到category，要在Build Setting 裡面設定 Other Linker Flags -> -ObjC -all_load

如果要重新編譯，記得先Clean一下工程，確保編譯成功
