A test program to demonstrate the
duration
and
repeatCount
properties
An alternative way to create a repeating animation is to use the
repeatDuration
property,
which tells the animation to repeat for a fixed time period instead of for a fixed number of
iterations. You can even set a property called
autoreverses
(of type
BOOL
) to make the
animation play backward during each alternate cycle. This is great for playing a nonlooping
animation continuously, such as a door swinging open and then shut (see Figure 9.2).
