使用python脚本实现iOS图片资源压缩

最近公司有一个新的需求,要把代码进行瘦身,这篇博客记录下如何对图片进行压缩的。

原理:
写一个脚本,把图片文件夹'.xcassets'的所有文件遍历出来,然后使用一个第三方的算法把图片压缩后再替换回去

成果:
image.png

由于在该工程中的png图片已经压缩过了,这次只压缩了jgp为后缀的图片,可以看出,还是有效果的

代码如下:

import os
import tinify
import shutil

tinify.key = '5J54hg59ysAuhHFPxXB*******'

source_file = '/Users/user/Desktop/Hotel.xcassets'
dest_file = '/Users/user/Desktop/destimages'


def getPngFileNames(source_dir):
    pngDicts = []
    for (parent, dirnames, filenames) in os.walk(source_dir):
        for filename in filenames:
            if filename.endswith('.jpg'):
                tempDict = {}
                tempDict['name'] = filename
                tempDict['path'] = os.path.join(parent, filename)
                pngDicts.append(tempDict)

    return pngDicts

def compressImages(uncompress_images):
    for pngDict in uncompress_images:
        source = tinify.from_file(pngDict['path'])
        source.to_file(os.path.join(dest_file, pngDict['name']))

def replace_file(new_path, old_path):
    pngs = getPngFileNames(source_file)
    for name in os.listdir(new_path):
        for pngDict in pngs:
            if pngDict['name'] == name:
                shutil.copyfile(os.path.join(new_path, name), pngDict['path'])


if __name__ == '__main__':
    replace_file(dest_file, source_file)
    # pngs = getPngFileNames(source_file)
    # compressImages(pngs)
    print('done')
