If you’re just sitting down to code up your first touch based application, you may want to take a moment to check out this touch gesture guide from Craig Villamor, Dan Willis, and Luke Wroblewski. The guide lists off 31 basic touch gestures that you should probably be implementing instead of creating your very own from scratch. Trust us, your customers will thank you.
The guide is in PDF format, so you can either save it directly to your iOS device of choice (or Mac for that matter), or print it out for quick reference. It’s a handy little reference to have access to, espeically if you’re just getting your feet wet with iOS development.
