app图标
先贴脚本地址autoExportAppIcon
1、介绍
作为iOS开发者，或多或少要接触到app图标切图，对于公司没有美工或者美工对iOS图标尺寸不了解的iOS开发者来说，每次制作图标要么自己切图半天，要么跟美工解释半天，心也是很累。索性写了个脚本直接生成图标，一分钟换图标，不要太爽！
2、原理及用法
脚本使用python写的，用的库是有名的PIL库。让美工提供一张不小于1024x1024的方图，针对不同尺寸图标设置resize图片，并修改Contents.json(app图标信息文件，xcode中需要)。
用法：下载脚本，并在终端下执行python /path/autoExportAppIcon.py /path/image.jpg
终端
icons
在xcode中新建
AppIcon:
AppIcon
打开
AppIcon文件夹:
appIcon Folder
Folder
将生成的图标及
Content.json文件替换就行了。
3、贴代码

if success == 0:
print('\033[7;32m' + 'Image模块安装成功.' + '\033[0m')

else:
print ('\033[31m' + 'Image安装失败，请手动在终端执行：\'python -m pip install Image\'重新安装.' + '\033[0m')
