Issue while scrolling below 0 offset of scroll view

[kanwarpal]

Hi,

I have faced an issue in scrolling images when we scroll very fast and scroll view offset becomes -ve, i that case app will crash

Can you please check the code?

I have fixed that in below method
by adding

if(_scroller.contentOffset.x < 0)
return;

• (void)scrollingHasEnded {

  _isScrolling = NO;
  if(_scroller.contentOffset.x < 0)
  return;
  NSUInteger newIndex = floor( _scroller.contentOffset.x / _scroller.frame.size.width );

  // don't proceed if the user has been scrolling, but didn't really go anywhere.
  if( newIndex == _currentIndex )
  return;

  // clear previous
  [self unloadFullsizeImageWithIndex:_currentIndex];

  _currentIndex = newIndex;
  [self updateCaption];
  [self updateTitle];
  [self updateButtons];
  [self loadFullsizeImageWithIndex:_currentIndex];
  [self preloadThumbnailImages];
  }

If its fine then please update the code so that in future if anyone use this then should not face this issue.

Thanks
