1. include UIAccelerometerDelegate in .h file

2. Declare UIAccelerationValue acceleration[3]; in .h

3. [[UIAccelerometer sharedAccelerometer] setDelegate:self]; in ViewDidLoad or ViewWillAppear

4. - (void)accelerometer:(UIAccelerometer *)accelerometer didAccelerate:(UIAcceleration *)acceleration

} // Delegate method

- (void)updateHistoryWithX:(float)x Y:(float)y Z:(float)z {

NSLog(@"X=%f Y=%f Z=%f ",x,y,z);
}
