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： 代码：

脚本环境要求Python 2.7PIL 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 screenshotfilename：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512×512，70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。GitHub地址以上所述是小编给大家介绍的教你用Python脚本快速为iOS10生成图标和截屏的全部叙述，希望对大家有所帮助，如果大家有任何疑问请给我留言，小编会及时回复大家的。在此也非常感谢大家对网站的支持！自己不喜欢的人，可以报之以沉默微笑；
