添加Run Script Phase

添加的内容如下：

APP_PATH="${TARGET_BUILD_DIR}/${WRAPPER_NAME}"

# This script loops through the frameworks embedded in the application and
# removes unused architectures.
find "$APP_PATH" -name '*.framework' -type d | while read -r FRAMEWORK
do
FRAMEWORK_EXECUTABLE_NAME=$(defaults read "$FRAMEWORK/Info.plist" CFBundleExecutable)
FRAMEWORK_EXECUTABLE_PATH="$FRAMEWORK/$FRAMEWORK_EX ECUTABLE_NAME"
echo "Executable is $FRAMEWORK_EXECUTABLE_PATH"

EXTRACTED_ARCHS=()

for ARCH in $ARCHS
do
echo "Extracting $ARCH from $FRAMEWORK_EXECUTABLE_NAME"
lipo -extract "$ARCH" "$FRAMEWORK_EXECUTABLE_PATH" -o "$FRAMEWORK_EXECUTABLE_PATH-$ARCH"
EXTRACTED_ARCHS+=("$FRAMEWORK_EXECUTABLE_PATH-$ARCH")
done

echo "Merging extracted architectures: ${ARCHS}"
lipo -o "$FRAMEWORK_EXECUTABLE_PATH-merged" -create "${EXTRACTED_ARCHS[@]}"
rm "${EXTRACTED_ARCHS[@]}"

echo "Replacing original executable with thinned version"
rm "$FRAMEWORK_EXECUTABLE_PATH"
mv "$FRAMEWORK_EXECUTABLE_PATH-merged" "$FRAMEWORK_EXECUTABLE_PATH"

done

优化

每次打包都要添加这个脚本，打包之后再运行时，还要删除这个脚本，难免有些麻烦，因此我想到了一个更好的解决办法。
我们在项目路径下新建一个脚本文件

touch Remove_i386.sh
vim  Remove_i386.sh//编辑文本将上面的脚本内容放到此文件中

然后在Xcode中的Run script中，添加下面的Shell命令，判断为Release模式下再去执行我们的这个脚本文件，

if [ "${CONFIGURATION=}" == "Release" ]; then
$SRCROOT/Remove_i386.sh
fi

这样我们就不用每次打包时都要去添加这个脚本，只添加这一次就可以了。
