app圖標
先貼腳本地址autoExportAppIcon
1、介紹
作為iOS開發者，或多或少要接觸到app圖標切圖，對于公司沒有美工或者美工對iOS圖標尺寸不了解的iOS開發者來說，每次制作圖標要么自己切圖半天，要么跟美工解釋半天，心也是很累。索性寫了個腳本直接生成圖標，一分鐘換圖標，不要太爽！
2、原理及用法
腳本使用python寫的，用的庫是有名的PIL庫。讓美工提供一張不小于1024x1024的方圖，針對不同尺寸圖標設置resize圖片，并修改Contents.json(app圖標信息文件，xcode中需要)。
用法：下載腳本，并在終端下執行python /path/autoExportAppIcon.py /path/image.jpg
終端
icons
在xcode中新建
AppIcon:
AppIcon
打開
AppIcon文件夾:
appIcon Folder
Folder
將生成的圖標及
Content.json文件替換就行了。
3、貼代碼

# coding: utf-8

print('\033[7;32m' + 'Image模塊安裝成功.' + '\033[0m')

else:
print ('\033[31m' + 'Image安裝失敗，請手動在終端執行：\'python -m pip install Image\'重新安裝.' + '\033[0m')
