iOS app图标一键生成

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

import sys
import os

try:
    from PIL import Image
except:
    print ('\033[31m' + '缺少Image模块，正在安装Image模块，请等待...' + '\033[0m')
    success = os.system('python -m pip install Image')
    if success == 0:
      print('\033[7;32m' + 'Image模块安装成功.' + '\033[0m')
      from PIL import Image
    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')
      quit()

outPutPath = os.path.expanduser('~') + '/Desktop/AppIcon/'

if not os.path.exists(outPutPath):
    os.mkdir(outPutPath)

if len(sys.argv) <= 1:
    print ('\033[31m' + '请输入图片路径,eg: python autoExportAppIcon.py /path/xxx.png' + '\033[0m')
    quit()
