Figure 4.2
The red subview on the right is clipped to the
cornerRadius
of its superview.
As you can see, the red view on the right is clipped to the curve of its superview.
It is not possible to control the curvature of each layer corner independently, so if you want
to create a layer or view that has some sharp and some rounded corners, you'll need to find
a different approach, such as using a
layer mask
(as covered later in the chapter) or
CAShapeLayer
(see Chapter 6, “Specialized Layers”).
