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

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)
