@implementation MyView

+ (Class)layerClass
{
	return [AngleGradientLayer class];
}

- (id)initWithFrame:(CGRect)frame
{
	if (!(self = [super initWithFrame:frame]))
		return nil;

	AngleGradientLayer *l = (AngleGradientLayer *)self.layer;
	l.colors = [NSArray arrayWithObjects:
		(id)[UIColor colorWithRed:0 green:0 blue:0.5 alpha:1].CGColor,
		(id)[UIColor colorWithRed:1 green:1 blue:0.4 alpha:1].CGColor,
		nil];
