Yeah, so this is something you are doing wrong. SnapView doesn't have a delay like that. If you are interested you can review my SnapView walkthrough: http://blog.jerrynixon.com/2012/12/walkthrough-implementing-snapview-in.html
Without a code sample from your app, this is the best I can offer right now. But hopefully this will be all you need to get on the right path for SnapView. Best of luck!
