利用shell脚本抽取ipa中的图片资源

目的很简单,就是从ipa包中抽取图片资源,然后按照ipa中的目录结构存放.

#!/bin/sh

#usage:extra-p_w_picpath-from-ipa <ipa-file>|<Payload-dir> <target-dir>

echo $#

if [[ $# != 2 ]]; then

echo "extra-p_w_picpath-from-ipa <ipa-file>|<Payload-dir> <target-dir>"

exit 1

fi

IPA_FILE=$1

TARGET_DIR=$2

if [[ -f "$IPA_FILE" ]]; then

echo "解压ipa包到临时目录"

IPA_DIR="/tmp/extra-p_w_picpath-from-ipa/temp/`date "+%Y%m%d-%H%M%S"`"

echo "temp-dir: " $IPA_DIR

#rm -rf $IPA_DIR

mkdir -p $IPA_DIR

echo "unzip $IPA_FILE begin ..."

unzip -q "$IPA_FILE" -d "$IPA_DIR"

if [[ $? != 0 ]]; then

echo "unzip $IPA_FILE failed"

exit 2

else

echo "unzip $IPA_FILE successed"

fi

# 定位到*.app目录

IPA_DIR="$IPA_DIR/""Payload/""`ls "$IPA_DIR/"Payload`"

else

IPA_DIR=$IPA_FILE

fi

copy_p_w_picpath()

{

#echo "begin copy p_w_picpath"

R="$1"

D="$2"

S="$3"

#echo "建立和ipa包相同层次的目录机构"

T=${S/$R/$D}

mkdir -p `dirname $T`

cp -rf $S $T

if [[ $T =~ \.png$ ]]; then

#echo "利用PNGCrush还原被优化的png图片"

mv $T $T.orign

xcrun -sdk iphoneos pngcrush -revert-iphone-optimizations -q $T.orign $T

if [[ $? != 0 ]]; then

echo "revert failed: " $T.orgin

else

rm $T.orign

fi

fi

#echo "end copy p_w_picpath"

}

# 导出函数 供下面的find方法使用

export -f copy_p_w_picpath

echo "copy jpg p_w_picpath"

find "$IPA_DIR" -name "*.jpg" -exec sh -c "copy_p_w_picpath $IPA_DIR $TARGET_DIR {}" \;

echo "process png p_w_picpath"

find "$IPA_DIR" -name "*.png" -exec sh -c "copy_p_w_picpath $IPA_DIR $TARGET_DIR {}" \;

echo "finished"
