文件扩展名

最近开发过程中遇到了一个很低级的问题,有点类似网盘app里面要区分各种文件类型,然后找出对应的文件归属icon并显示,做为一个极客精神的iOS开发者,我想找到一种文件扩展名集合并不需要自己命名枚举值,这时我想起2015年左右开发百度网盘时调研过的airdrop,其中苹果规定了分享文件到其它手机需要提供的文件唯一标识(UTI),于是我找了一下文档记录一下如下的文件类型列表.

苹果的CoreServices.framework中有一个UTCoreTypes.h头文件记录了所有的文件类型.

下面是我去掉所有注释的代码.当然这些仅限于苹果内部可识别的类型,那些不太常用的类型文件或者自定义扩展名文件类型在这里就不赘述了,如果需要搞个通配类型即可,或者单独处理.
