fix LayerKit framework不能提交App Store

- 问题：

- 原因

x86_64, i386是ios模拟器用的architectures.发布时，不支持这两种。但是，默认编译出来的layerkit framework支持这两种编译器

- 解决办法

查看layerkit.frameowk所支持的architecture,可以仿照此命令

$ lipo -info Vendor/RAC/ReactiveCocoa.framework/ReactiveCocoa

→ Architectures in the fat file: ReactiveCocoa are: i386 x86_64 armv7 arm64

接下来便是，让layerkit.frameowk不支持i386 x86_64这两种architecture,做法如下:

　　1. Add a Run Script

　　2.  set it to use /bin/sh

　　3. 添加如下脚本

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_EXECUTABLE_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
