methods. If the gesture recognizer eats these touches, then users will not
be able to draw lines.
When you set
cancelsTouchesInView

UIResponder
methods. This allows both
the recognizer and the view's
UIResponder
methods to handle the same touches. If
you're curious, comment out the line that sets
cancelsTouchesInView
to
NO
and
build and run again to see the effects.
