How to get accelerometer data in IOS?

Question

I am using the UIAccelerotmeterDelegate method accelerometer:didAccelerate: but recently that method has been deprecated in iOS 5.0. So what is the alternative way

Answer 1

Here is a useful sample code I found for CoreMotion from this link.

    @interface ViewController ()

    @property (nonatomic, strong) CMMotionManager *motionManager; 
    @property (nonatomic, strong) IBOutlet UILabel *xAxis; 
    @property (nonatomic, strong) IBOutlet UILabel *yAxis; 
    @property (nonatomic, strong) IBOutlet UILabel *zAxis; 

    @end

    @implementation ViewController
    - (void)viewDidLoad 
    { 
      [super viewDidLoad];

      self.motionManager = [[CMMotionManager alloc] init]; 
      self.motionManager.accelerometerUpdateInterval = 1;

      if ([self.motionManager isAccelerometerAvailable]) 
      { 
        NSOperationQueue *queue = [[NSOperationQueue alloc] init];
        [self.motionManager startAccelerometerUpdatesToQueue:queue withHandler:^(CMAccelerometerData *accelerometerData, NSError *error) {
            dispatch_async(dispatch_get_main_queue(), ^{ 
              self.xAxis.text = [NSString stringWithFormat:@"%.2f",accelerometerData.acceleration.x]; 
              self.yAxis.text = [NSString stringWithFormat:@"%.2f",accelerometerData.acceleration.y]; 
              self.zAxis.text = [NSString stringWithFormat:@"%.2f",accelerometerData.acceleration.z];
            });
          }]; 
      } else 
      NSLog(@"not active"); 
    }
@end
