iOS项目冗余资源扫描脚本

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。
