How does Apple VI set ringtones and WeChat message ringtones?

There are two main ways to set iphone ringtones through itunes:

Intercept the music within 40 seconds by yourself, convert the format in itunes and synchronize it with your mobile phone (this method is a little more complicated).

① Download ringtone app, and then download ringtones directly in this app.

2 ringtone apps will have tutorial guidance, and you need to connect to itunes for mobile phone synchronization.

The advantage of this method is that you don't need to convert the file format yourself, just synchronize it to your mobile phone.

The disadvantage is that the ringtone has been cut to the right length, and you need to find what you like. There are many cache files.

Note: iphone has limited memory. Clean up the cache file in time.
