iOS detect direction drag in UIVIEW

Have you read the documentation on multi-touch events ?

http://developer.apple.com/library/...s.html#//apple_ref/doc/uid/TP40009541-CH3-SW1

There are examples there for a simple "Touch and move" which is what a drag is I imagine.

I'd start by reading the UISwipeGestureRecognizer class reference.

Edit:
Or the UIPanGestureRecognizer class reference. From your post I'm not sure if you're looking to detect a swipe or drag.

The guide I pointed to provides all the information to do single and multi touch. Did you look at it ?

There's 2 things here : Event Handling for multi touch events (including single touch, ie, touchesEnded, touchesBegan, etc..) and Gesture Recognizer (linked in the content bar on the left in the guide I pointed to).

That's basically the whole documentation on what you want to do.
