It seems fairly straightforward, if a little labor intensive, to figure out the width and placement of all your image views, override -layoutSubviews to position only the ones that are potentially visible, and implement -scrollViewWillEndDragging:withVelocity:targetContentOffset: to figure out where to end scrolling, based on the current velocity. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
