36 |  OBGradientView is a simple UIView wrapper for CAGradientLayer. It is a plain UIView whose layer
37 |  is a CAGradientLayer. It is useful if using a view is more convenient than using a layer, e.g.
38 |  because you want to use autoresizing masks.
39 |  
40 |  OBGradientView exposes all of the layer's gradient-related properties.
41 |  The getters and setters just forward the calls to the layer so the syntax is just the same as
42 |  for CAGradientLayer's properties itself. See the documentation for CAGradientLayer for details:
43 |  http://developer.apple.com/iphone/library/documentation/GraphicsImaging/Reference/CAGradientLayer_class/Reference/Reference.html
44 |  
45 |  The one exception to this is the colors property: in addition to an array of CGColorRefs,
46 |  it also accepts an array of UIColor objects. Likewise, the getter returns an array of UIColors.
47 |  If you need CGColorRefs, access gradientLayer.colors instead.

 1 | # OBGradientView
 2 | 
 3 | OBGradientView is a simple UIView wrapper for [CAGradientLayer][CAGradientLayerReference]. It is a
 4 | plain UIView whose layer is a CAGradientLayer. It is useful if using a view is more convenient than
 5 | using a layer, e.g. because you want to use autoresizing masks.
 6 |  
 7 | OBGradientView exposes all of the layer's gradient-related properties. The getters and setters just
 8 | forward the calls to the layer so the syntax is just the same as for CAGradientLayer's properties itself.
 9 | See the [documentation for CAGradientLayer][CAGradientLayerReference] for details.
10 |  
11 | The one exception to this is the colors property: in addition to an array of CGColorRefs, it also accepts
12 | an array of UIColor objects. Likewise, the getter returns an array of UIColors. If you need CGColorRefs,
13 | access gradientLayer.colors instead.
