So a user opens the app and the volume level automatically changes to a level which the user initially picks during the setup of the app.

Additionally, could the volume level be picked for both headphone and non-headphone use, i.e. a volume level for when headphones are inserted in the jack and a volume level when the headphone are not in the jack.

  • I'm pretty sure you can't change the device's volume. Only the user can do that. A similar question has been discussed here: http://stackoverflow.com/questions/29049699/how-to-change-an-ios-device-volume-programmatically – Dos43 Jun 25 '15 at 04:31
