body: <p>How to scroll UIcollectionView automatically in Horizontal position using NSTimer</p>
  
  <p>I'm working on my project source below:</p>
  
  <pre><code>- (void)viewDidLoad {
      [super viewDidLoad];
  
      self.endPoint = CGPointMake(0, self.collectionView.frame.size.width);
      self.scrollingPoint = CGPointMake(0, 0);
      self.scrollingTimer = [NSTimer scheduledTimerWithTimeInterval:0.015 target:self selector:@selector(onTimer) userInfo:nil repeats:YES];
  
  }
  
  - (void)onTimer {
       self.collectionView.contentOffset = self.scrollingPoint;
      if (CGPointEqualToPoint(self.scrollingPoint, self.endPoint)) {
          [self.scrollingTimer invalidate];
      }
      self.scrollingPoint = CGPointMake(self.scrollingPoint.x+1, 0);
  }
  </code></pre>
  
  <p>Tried with the above code, but is not working for me.</p>
