Gold Challenge: Another View and Curves
Make another
UIView
subclass. This subclass should draw the Big Nerd Ranch logo. (For
the logo, use the file that you used for the application icon of the
Quiz
application.)
The logo should be clipped to a circle that contains just the hat. The logo should have a
black outline with a shadow underneath it. Also, the circle should have a slightly blue
gradient coming from the top of the circle to the center of it. This view instance should be a
subview of the
HypnosisView
. (Hint: you will need to use
UIImage
,
CGColor-
SpaceRef
,
CGGradientRef
,
CGContextClip
and a few other functions and types
you have seen in previous challenges and this chapter.)
