title: "Property access result unused - getters should not be used for side effects" warning
body: <p>I am trying to start the accelerometer and send a message to the user based on the accelerometer's data values. However, when I am trying to initialize accelerometer processes, I get the following warning: "Property access result unused - getters should not be used for side effects" </p>
  
  <pre><code>- (void)viewDidLoad
  {
  [super viewDidLoad];
  self.motionManager = [[CMMotionManager alloc] init];
  self.motionManager.accelerometerUpdateInterval = 0.04;
  self.motionManager.startAccelerometerUpdates;
  [self.motionManager startAccelerometerUpdatestoQueue:[NSOperationQueue current
  Queue] withHandler:^(CMAccelerometerData *accelerometerData, NSError *error)
  </code></pre>
  
  <p>I get the error on line 6. Any help is appreciated!</p>
