- (void)scrollViewDidEndDragging:(UIScrollView *)_scrollView willDecelerate:(BOOL)decelerate {
if(!decelerate)
[self snapToPosition:_scrollView];
}

It seems to be a lot cleaner. That way the scrollViewDidDecelerate deals with when the scroll view is flicked and the scrollViewDidEndDragging deals with when the user doesn’t flick.

Minor change to fix some unstable behaviour and conflict between the two methods that I thought might be useful to share. Really helpful otherwise. Thanks

Thanks for the post. I found it extremely useful. The current design implies that the width of the view is twice that of the images or whatever uiview. In my case, I needed to make the center view large, hence making the left and right placeholders are smaller. Here’s the math that works: (monotouch C#)

float messageWidth = 550f, scrollerWidth = 1024f,
initialOffset = (1024f-550f)/2f;

svMessagesView.Scrolled += delegate(object sender, EventArgs e) {
UIScrollView s = (UIScrollView)sender;
float offset = s.ContentOffset.X/(scrollerWidth/initialOffset/2f);
CGAffineTransform transform = CGAffineTransform.MakeTranslation(offset, 0);
messageContainer.Transform = transform;
};

initialOffset – are the widths of the slices on the sides.

ludo: if u want your images in middle of screen u need to set right positions for images in contentView, considering your new paging size

Now, I look forward to a SHOTGUN DUEL!!
