How to set iOS's ringtone from a tweak [duplicate]

This question already has an answer here: Closed 11 years ago.

i'm writing a tweak for iPhone that at certainly point needs to set the ringtone, but i'm not able to find how to do that. Can someone tell me how to do that, put me in the right direction where to look or just tell me a website where to search or maybe in some wiki? All i've found are useless answers.

More Info: I need to know how to set ringto开发者_Go百科ne for a tweak so the solution can be only for jaibroken devices.

Thanks!

You cannot set the user's ringtone using the iOS SDK. If you need this ability, consider filing an enhancement request at https://feedbackassistant.apple.com/. However, as this feature would annoy the unholy poop out of almost every user on the platform, don't hold your breath.
