Hi Dave, What about if you have some repetition of the images? Say the following is a container UIView that has all of your UIImageViews stacked horizontally and the width of the following view is far smaller than that of the UIScrollView it's contained in. The gray areas are duplicated image views, and the the white area is the "true" set of images.
Say that in the previous image, the leftmost person is the first logical image
in your set of data. In your viewDidLoad, you could set the contentOffset to
the position of the first Person (ie. the leftmost white edge) with something
like:
- (void)viewDidLoad
{
CGFloat someXPos = CGRectGetWidth([pictures frame]) +
CGRectGetWidth([reticle frame]);
[scrollView setContentOffset:someXPos];
}
Then, once the user breaches the threshold value that has duplicates (the gray
areas), you call the following:
- (void)scrollViewDidScroll:(UIScrollView *)scrollView
{
[scrollView setContentOffset:someXPos animated:NO];
}
The intent is that the scroll view snaps the container UIView back to a
position that contains no duplicates. The view has duplicates to account for
the period of time between sampling of scroll events. Note that this suggestion
is assuming that the images are fairly small, so that loading them all doesn't
cause too much memory pressure (which is what I understood from earlier
messages).
