I'm currently working on a music player app, and like the iPod application, I would like to shuffle songs with shake gesture.
I'm implementing motion methods like Apple recommends to, and in foreground everything works fine.
- (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event;
- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event;
- (void)motionCancelled:(UIEventSubtype)motion withEvent:(UIEvent *)event;
But I just can't figure out how to call those methods from background. I've looked all over the internet, and there's not threads about this.
first things first: is it possible?
Thanx!
It's not possible now, whether you use iOS 4 or any lower SDK version.
