准备一张 1024 * 1024 的png图片
1. 在项目根目录中创建文件()

mkdir tmp.iconset 

2. 生成多个比例不同的图片

sips -z 16 16 logo.png --out tmp.iconset/icon_16x16.png
sips -z 32 32 logo.png --out tmp.iconset/icon_16x16@2x.png
sips -z 32 32 logo.png --out tmp.iconset/icon_32x32.png
sips -z 64 64 logo.png --out tmp.iconset/icon_32x32@2x.png
sips -z 128 128 logo.png --out tmp.iconset/icon_128x128.png
sips -z 256 256 logo.png --out tmp.iconset/icon_128x128@2x.png
sips -z 256 256 logo.png --out tmp.iconset/icon_256x256.png
sips -z 512 512 logo.png --out tmp.iconset/icon_256x256@2x.png
sips -z 512 512 logo.png --out tmp.iconset/icon_512x512.png
sips -z 1024 1024 logo.png --out tmp.iconset/icon_512x512@2x.png

3. 生成 icns

iconutil -c icns tmp.iconset -o icon.icns

　　

4. 修改配置文件 
package.json
