Nice simple bit of Gyro code

 - (void)viewDidLoad

{

    [super viewDidLoad];

    

    _manager = [[CMMotionManager alloc]init];

    _manager.gyroUpdateInterval = 0.1;

    

    NSOperationQueue *queue = [NSOperationQueue mainQueue];

    

    void (^handler)(CMGyroData *data, NSError *error) = ^(CMGyroData *data, NSError *error){

        _lblX.text = [NSString stringWithFormat:@"%f", data.rotationRate.x];

        _lblY.text = [NSString stringWithFormat:@"%f", data.rotationRate.y];

        _lblZ.text = [NSString stringWithFormat:@"%f", data.rotationRate.z];

    };

    

    [_manager startGyroUpdatesToQueue:queue withHandler:handler];

    

    

}
