(On the iphone Apple's finger tracking isn't very reliable anyway so it's best to ignore the finger number and just figure out the gestures from the reported positions.)

Doesn't it give you events based on the gesture it detected?

No.

Basically, you get the x/y coordinates and do the rest yourself. Apple is constantly updating APIs though with documentation lagging behind so the newest version of the API might have built-in gesture detection.
