概述
之前用的一个批量导出APP图标和启动图的软件,今天发现收费了,于是自己造了个简单的轮子。
实现
Mac上的sips
命令,可以很方便的帮助用户修改图片尺寸
Xcode里面的APP启动图资源包含两部分
- 图片资源
- 描述文件
所以这个脚本的功能就是两个
- 生成描述文件
Contents.json
- 修改图片尺寸并关联描述文件
生成描述文件
使用echo
简单粗暴的写入
setContents(){
echo { >> ./AppIcon/Contents.json
echo " \"images\"" : [>> ./AppIcon/Contents.json
echo " "{>> ./AppIcon/Contents.json
echo " \"size\"" : "\"20x20\"",>> ./AppIcon/Contents.json
echo " \"idiom\"" : "\"iphone\"",>> ./AppIcon/Contents.json
echo " \"scale\"" : "\"2x\"",>> ./AppIcon/Contents.json
echo " \"filename\"" : "\"icon_40x40.png\"">> ./AppIcon/Contents.json

}
修改图片尺寸
iconWithSize() {
sips -Z $1 icon.png --out ./AppIcon/icon_$1x$1.png
}
函数调用
mkdir AppIcon
setContents
for size in 40 58 60 80 87 120 180 1024
do
iconWithSize $size
done
image

怎么使用
AppIcon
下载对应的sh
文件,放到你想导出图片的目录下,将你的原图命名为icon.png
,然后在控制台中进入该目录,执行
sh AppIcon.sh
LaunchImage
下载对应的sh
文件,放到你想导出图片的目录下,将你的原图命名为Default.png
,然后在控制台中进入该目录,执行
sh AppLaunch.sh
就可以得到你要的资源啦。
扩展
在命令行使用sips
命令修改图片尺寸
重新定义单个图片尺寸(忽略比例)
sips -z 768 1024 xxx.png
修改后图片尺寸为1024x768
重新定义单个图片尺寸(保留比例)
sips -Z 500 xxx.png
==保留图片比例,宽高不超过500。注意是大写的Z==。要想保留图片原始比例就得这样做,比如你有一张尺寸为750 x 1334
的图片,执行完上面这条命令后,图片尺寸就变成了281x500
在一个目录里批量修改同一后缀格式的图片尺寸
sips -Z 300 *.png
只需要用*
作为通配符来代替图片名就可以了
