问题
Is there any way to play UILocalNotification Sound even if Sound is off. Actually I am trying to create an alarm which works even if user has turned off the sound. Or any alternative way to achieve this.
回答1:
If user has put the sound to off, there is no way for the app to play the sound. User settings always have the highest priorities than the applications.
