- (void)accelerometer:(UIAccelerometer *)accelerometer didAccelerate:(UIAcceleration *)acceleration {

if (fabsf(acceleration.x) > kAccelerationThreshold ||

}

}

this went in the - (void)viewDidLoad {

UIAccelerometer *accel = [UIAccelerometer sharedAccelerometer];
accel.delegate = self;
accel.updateInterval = kUpdateInterval;
