关于iPhone语音备忘录访问

1主动访问

例如微信可以通过访问iCloud访问语音备忘录的文件；也就是iCloud访问方式；

2 被动发送

      点击语音备忘录，共享给APP，共享录音

    （1）在“语音备忘录”列表中，轻点已存储的录音。

    （2）轻点 。。。

     （3）轻点 ，然后选取一个共享选项或将录音存储到 iCloud 云盘。

大概的原理是这样的，首先为我们的iOS应用注册可以打开document types(文档类型)，然后在第三方应用中，如果它们使用了iOS提供的分享功能，那么就会看到我们的应用程序，点击进行分享--HiroGuo

3被动访问的时候，需要你的APP有被分享的权限：
