On a CAShapeLayer
, I've drawn a closed UIBezierPath
. I can fill this shape by setting the fillColor
, however I want to fill the shape with a gradient. How can I set up the CAGradientLayer
so it clips to the shape outlined by the bezier path?
A draft example would be the following:
...
CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB();
CGContextRef context = UIGraphicsGetCurrentContext();
UIColor *gradientColor = [UIColor colorWithRed:0.51 green:0.0 blue:0.49 alpha:1.0];
NSArray *gradientColors = [NSArray arrayWithObjects:
(id)[UIColor blueColor].CGColor,
(id)gradientColor.CGColor,
(id)[UIColor redColor].CGColor, nil];
CGFloat gradientLocations[] = {0, 0.5, 1};
CGGradientRef gradient = CGGradientCreateWithColors(colorSpace, (CFArrayRef)gradientColors, gradientLocations);
UIBezierPath *roundedRectanglePath = [UIBezierPath bezierPathWithRoundedRect:CGRectMake(10, 10, 200, 200) cornerRadius:6];
CGContextSaveGState(context);
[roundedRectanglePath fill];
[roundedRectanglePath addClip];
CGContextDrawLinearGradient(context, gradient, CGPointMake(10, 10), CGPointMake(210, 10), 0);
CGColorSpaceRelease(colorSpace);
CGGradientRelease(gradient);
