切到工程的 build phases，点左上角的+号，选择 New Run Script Phase，
添加脚本代码
APP_PATH="${TARGET_BUILD_DIR}/${WRAPPER_NAME}"
# This script loops through the frameworks embedded in the application and
# removes unused architectures.
find"$APP_PATH"-name'*.framework'-typed |whileread-r FRAMEWORK
do
FRAMEWORK_EXECUTABLE_NAME=$(defaultsread"$FRAMEWORK/Info.plist"CFBundleExecutable)
FRAMEWORK_EXECUTABLE_PATH="$FRAMEWORK/$FRAMEWORK_EXECUTABLE_NAME"
echo"Executable is $FRAMEWORK_EXECUTABLE_PATH"

done

echo "Replacing original executable with thinned version"
rm"$FRAMEWORK_EXECUTABLE_PATH"

最终效果如下图所示
