创建Framework的流程这里就不在多说，直接介绍生成通用Framework的方法；
1:在 TARGETS 中 点击“+”号，添加Aggregate；
2：在TARGETS——>MyFrameworkAggregate——>Build Phases 中点“+”号添加 Run Script
3：在Run Script中添加命令
# Sets the target folders and the final framework product.
FMK_NAME=${PROJECT_NAME}
# Install dir will be the final output to the framework.
# The following line create it in the root folder of the current project.
INSTALL_DIR=${SRCROOT}/Products/${FMK_NAME}.framework
# Working dir will be deleted after the framework creation.
WRK_DIR=build
DEVICE_DIR=${WRK_DIR}/Release-iphoneos/${FMK_NAME}.framework
SIMULATOR_DIR=${WRK_DIR}/Release-iphonesimulator/${FMK_NAME}.framework
# -configuration ${CONFIGURATION}
# Clean and Building both architectures.
xcodebuild -configuration "Release" -target "${FMK_NAME}" -sdk iphoneos -arch armv7 -arch armv7s -arch arm64 clean build
xcodebuild -configuration "Release" -target "${FMK_NAME}" -sdk iphonesimulator -arch x86_64 -arch i386 clean build
# Cleaning the oldest.
if [ -d "${INSTALL_DIR}" ]
then
rm -rf "${INSTALL_DIR}"
fi
mkdir -p "${INSTALL_DIR}"
cp -R "${DEVICE_DIR}/" "${INSTALL_DIR}/"
# Uses the Lipo Tool to merge both binary files (i386 + armv6/armv7) into one Universal final product.
lipo -create "${DEVICE_DIR}/${FMK_NAME}" "${SIMULATOR_DIR}/${FMK_NAME}" -output "${INSTALL_DIR}/${FMK_NAME}"
rm -r "${WRK_DIR}"
open "${SRCROOT}/Products/"
4：选择MyFrameworkAggregate 编译即可 command + B；
