/*
|
|
OBGradientView is a simple UIView wrapper for CAGradientLayer. It is a plain UIView whose layer
|
|
is a CAGradientLayer. It is useful if using a view is more convenient than using a layer, e.g.
|
|
because you want to use autoresizing masks.
|
|
|
|
OBGradientView exposes all of the layer's gradient-related properties.
|
|
The getters and setters just forward the calls to the layer so the syntax is just the same as
|
|
for CAGradientLayer's properties itself. See the documentation for CAGradientLayer for details:
|
|
http://developer.apple.com/iphone/library/documentation/GraphicsImaging/Reference/CAGradientLayer_class/Reference/Reference.html
|
|
|
|
The one exception to this is the colors property: in addition to an array of CGColorRefs,
|
|
it also accepts an array of UIColor objects. Likewise, the getter returns an array of UIColors.
|
|
If you need CGColorRefs, access gradientLayer.colors instead.
