audio - How to play a sound loop when an alert is displayed using UILocationNotification -

The sound is played only when a warning is shown using UILocationNotification. When a warning is displayed in the background of the sound Clock.app.

You can not play sound loop when ULocationNotification takes fire. You take a voice to play, and this sound should be less than 30 seconds, or the system sound will play instead. You can make the sound longer and repeat itself in the audio editor, but it is obvious that the size of the sound increases (and in the form of the iOS UP.Compressed formats such as the sound file in UCK like MP3 Does not support.)
