iOS项目冗余资源扫描脚本
随着iOS项目的版本不断迭代,app中冗余文件会越来越多,app size也持续增加,是时候需要对app冗余资源进行检测,对app进行瘦身。
使用方法:
1. 运行环境为mac, 首先准备好工程源代码;
2. 新建check.sh,将下面的代码粘贴到check.sh中并且保存;(可将txt文件改成sh后缀)
#!/bin/sh ##### several cases that the scripts does not work: ##### 1) there is space or slash in the resources file, such as "aaa .png" 资源文件名中含有空格或者/ ##### 2) reference resources in commented code 资源引用代码被注释了 ##### 3) you need to manually checked the resources one by one in the result 对于脚本检查结果,最好人工检查一遍 ##### 4) you can add some other types more than png, jpg, gif, wav, m4a 如果需要检查其他资源,请自行修改脚本; ##### 5)默认文件后缀都是如@2x.png格式,如果后缀格式不同,请自行修改脚本; #### set parameters:PrjPath为项目工程所在目录,包含.m .xib文件;ResPath为被扫描的资源文件目录,包含.png .wav #### xcodeprojPath为工程xcodeproj位置 PrjPath=/Users/....... ResPath=/Users/....... xcodeprojPath=/Users/....../******.xcodeproj if [ -f ~/Desktop/resource_san_result.txt ];then rm -f ~/Desktop/resource_san_result.txt fi cd $PrjPath files=$(find . -name "*.m" -o -name "*.xib" -o -name "*.mm" -o -name "*.plist") cd $ResPath for png in $(find . -name "*.png" -o -name "*.jpg" -o -name "*.gif" -o -name "*.wav" -o -name "*.m4a") do basename='basename/'$png basename=${basename##*/} # echo $basename if [ "${basename##*.}" == "png" ];then echo $basename|grep -q @2x.png if [ $? -eq 0 ];then name=${basename%%@2x.png} else echo $basename|grep -q @3x.png if [ $? -eq 0 ];then name=${basename%%@3x.png} else name=${basename%.png} fi fi elif [ "${basename##*.}" == "jpg" ];then echo $basename|grep -q @2x.jpg if [ $? -eq 0 ];then name=${basename%%@2x.jpg} else echo $basename|grep -q @3x.jpg if [ $? -eq 0 ];then name=${basename%%@3x.jpg} else name=${basename%%.jpg} fi fi elif [ "${basename##*.}" == "gif" ];then echo $basename|grep -q @2x.gif if [ $? -eq 0 ];then name=${basename%%@2x.gif} else echo $basename|grep -q @3x.gif if [ $? -eq 0 ];then name=${basename%%@3x.gif} else name=${basename%%.gif} fi fi elif [ "${basename##*.}" == "wav" ];then name=${basename%%.wav} elif [ "${basename##*.}" == "m4a" ]; then name=${basename%%.m4a} else name='' fi if [ ${#name} -gt 0 ];then # # name=${name%%[0-9]*} cd $PrjPath if grep -q $name $files;then echo "$png" is used else cd $xcodeprojPath if grep -q $name project.pbxproj;then echo "$png" is not used >> ~/Desktop/resource_san_result.txt else echo "$png" is not packaged fi fi else echo name is empty fi done if [ -f ~/Desktop/resource_san_result.txt ]; then echo ***************the end of scan. Please see result from resource_san_result.txt else echo ***************the end of scan, everything is OK fi
3. 设置脚本中参数:
PrjPath为项目工程所在目录,包含.m .xib文件;
ResPath为被扫描的资源文件目录,包含.png .wav;
xcodeprojPath为工程xcodeproj位置;
例如:
PrjPath=/Users/zhuquan/Documents/secret-develop/Project ResPath=/Users/zhuquan/Documents/secret-develop/Project/Phoenix/Res xcodeprojPath=/Users/zhuquan/Documents/secret-develop/Project/Phoenix.xcodeproj
4. 执行脚本check.sh;
5. 最后会出检测结果,检测出来的冗余资源最好人工检查一遍。
[zhuquandeMacBook-Pro:Desktop zhuquan$ ./check.sh ./1.png is used ./2.png is used ./3.png is used ./4.png is used ./5.png is used ./ajax-loader.gif is not packaged ./运动记录.png is not packaged ***************the end of scan, everything is OK
使用总结:
脚本使用过程中有一些注意事项如下,
1. 如果资源文件名中含有空格或者/,比如”aaa .png”,该资源无法正常检测;
2. 如果资源文件在代码中被引用了,但是该引用代码被注释掉了,也无法成功检测;
3. 对于最终脚本输出的脚本检查结果,最好人工检查一遍,有些资源可能并非是冗余资源;
4. 目前脚本中支持的资源类型有.png .jpg .gif .wav .m4a,如果需要检查其他资源,请自行修改脚本。
