what is the difference between touch and tap in iOS

Question

I am confused by the difference between touches and taps like touchUpInside event and one tap. Are they the same thing?

Answer 1

https://developer.apple.com/library/ios/documentation/EventHandling/Conceptual/EventHandlingiPhoneOS/GestureRecognizer_basics/GestureRecognizer_basics.html

A tap is the equivalent of a click, a rapid touch start and touch end (which counts as ONE event)

a touch can be lingering...you may touchdown, then move your finger to the button, then lifting your finger fires the touch up (inside the button)

Answer 2

I have found that taps are the number of taps for the gesture to be recognized.

Touches are the number of fingers required to tap for the gesture to be recognized.
