使用z library或者安娜档案馆下载epub格式的图书可以直接导入。

虽然PDF也支持导入，但是不建议。因为PDF一般是扫描版在手机上看很不方便，

其次PDF一般体积较大，iCloud同步不太方便

都说了文字图书，我来说说有声书怎么搞


首先感谢另一个回答中怎么讲录音或音频导入iPhone的ibook图书有声读物？@进击中的小石子 大佬导入有声读物的方案，其次再来说现阶段的iTunes如何导入有声读物：

1.打开iTunes，选择 文件-导入文件夹，选择自己存放音乐文件的地方导入

2.导入后可以在iTunes中点击文件名后方的三个小点，然后选择相应的音乐专辑、歌手等信息修改，尤其是专辑，多本有声书是按照专辑分的

3.全选（ctrl+a）选择所有专辑内的音乐，还是选择任意选中音乐的三个小点，选择显示简介，然后在弹窗中选择修改信息，在“选项”中把“音乐”更改为“有声书”就可以直接变成有声书了！！！不用转换格式！

4.然后按照小石子大佬的操作，同步有声书文件即可！


感谢知乎！感谢提问者！还是苹果的UI最简洁，讨厌国产播客的各种广告的各位，多年后你兜兜转转找到这个回答，希望能给你一点帮助！
