简介
这两天更新完Xcode8之后发现Xcode对图标的要求又有了变化,之前用的一个小应用“IconKit”还没赶上节奏,已经不能满足Xcode8的要求了。
于是就想起来用Python自己做个脚本来生成图标。
其实这个脚本很早就写了,现在为了适应iOS10,就修改完善下,并且放到了 GitHub 。
可以看看效果图:

脚本环境要求
Python 2.7
PIL or Pillow
笔者亲测,也许是笔者太菜,试了各种方法安装PIL总是出错,最后还是用了Pillow,效果一样的。
怎么使用脚本
在Windows的命令行或者Mac的终端,输入:
python tool.py [action] [filename] [platform]
action:icon 或者 screenshot
filename:图标文件名,截屏不需要文件名,自动遍历
platform:ios 或者 android
举一些例子:
生成iOS的图标:python tool.py icon icon.jpg ios
生成安卓的图标:python tool.py icon icon.jpg android
生成iOS的截屏:python tool.py screenshot ios
生成安卓的截屏:python tool.py screenshot android
注意注意
生成安卓圆角图标需要一张PNG来裁剪,尺寸512x512,70圆角,GitHub中已经附带。
生成截屏时会自动遍历所有JPG和PNG文件,自动识别横竖屏
结语
如果你觉得有用,欢迎在GitHub中Star一下,也欢迎改进,代码简单易懂加了注释。
