（转）打理一下IOS项目中的图片资源

#如果没有找包含@"imageName"或@"imageName.png"的.h.m文件,则认为项目里不再需要这个图片
find ./Resources -name "*.png" \
|grep -v @ \
|while read line;do
iname=$(basename "$line"|sed -e "s/\.png//");
[ -z "`find ./ \( -name "*.m" -or -name "*.h" \)|xargs grep -E "@\\\"${iname}(\\\.png)?\\\""`" ] && echo $line && img2x="`echo "$line"|sed -e "s/\.png/@2x\.png/"`" && [ -e "$img2x" ] && echo $img2x;
done

find ./Resources -name "*.png" \
|while read line;do
iname=$(basename "$line"|sed -e "s/\.png//" -e "s/@2x//");
dname="$(dirname "$line")/"
[ ! -e "${dname}${iname}.png" ] && echo "$line 缺少单倍图片"
[ ! -e "${dname}${iname}@2x.png" ] && echo "$line 缺少2倍图片"
done
