title: Everything is correct but still my scrollView is not scrolling?
body: <p>Its very common for we all to use UIScrollView i have taken the one on xib, and have set its all properties well, It was scrolling at start but latter on i put one more view in it and it stopped to scroll, </p>
  
  <pre><code>[scroll setContentSize:CGSizeMake(containerViewOfRecurrence.frame.size.width, 1000)];
  scroll.pagingEnabled = NO;
  scroll.delegate      = self;
  scroll.scrollEnabled = YES;
  scroll.clipsToBounds = YES;
  
  [scroll setBackgroundColor:[UIColor clearColor]];
  </code></pre>
  
  <p>I have added the delegate method to detect the scroll, </p>
  
  <pre><code>- (void)scrollViewDidScroll:(UIScrollView *)scrollView {
      NSLog(@"%f", scrollView.contentOffset.y);
  }
  </code></pre>
  
  <p>and which does not get called on scrolling.</p>
  
  <p>Here are the images of xib</p>
