I have a problem clipping a view using CAShapeLayer-UIBezierPath , I want to clip the content but I end up getting a stroke (frame) with that UIBezierPath , This is my code
UIBezierPath *path2Path = [UIBezierPath bezierPath];
[path2Path moveToPoint:CGPointMake(206.745, 0)];
[path2Path addLineToPoint:CGPointMake(206.745, 97.613)];
[path2Path addLineToPoint:CGPointMake(0, 97.613)];
[path2Path addLineToPoint:CGPointMake(0, 0)];
[path2Path addLineToPoint:CGPointMake(87.28, 0)];
[path2Path addCurveToPoint:CGPointMake(103.808, 12.118) controlPoint1:CGPointMake(87.28, 0) controlPoint2:CGPointMake(86.555, 12.118)];
[path2Path addCurveToPoint:CGPointMake(119.466, 0) controlPoint1:CGPointMake(121.061, 12.118) controlPoint2:CGPointMake(119.466, 0)];
[path2Path addLineToPoint:CGPointMake(206.745, 0)];
[path2Path closePath];
[path2Path addClip];
CAShapeLayer *pathLayer = [CAShapeLayer layer];
pathLayer.frame=MYVIEW.bounds;
pathLayer.path = path2Path.CGPath;
pathLayer.strokeColor = [[UIColor blackColor] CGColor];
pathLayer.fillColor = [[UIColor clearColor] CGColor];
pathLayer.fillRule=kCAFillRuleEvenOdd;
[MYVIEW.layer setMask:pathLayer];
[MYVIEW.layer setMasksToBounds:YES];
MYVIEW.backgroundColor=[UIColor greenColor];
The result of this code is just a green stroke line ,the bounds is empty , like this https://i.sstatic.net/aehdo.png
However , I want to make the bounds green , clipped by that stroke
as rob mayoff said You can do this easily by setting your view's layer mask to a CAShapeLayer.
UIBezierPath *myClippingPath = ...
CAShapeLayer *mask = [CAShapeLayer layer];
mask.path = myClippingPath.CGPath;
myView.layer.mask = mask;
In Swift
let myClippingPath = UIBezierPath( ... )
let mask = CAShapeLayer()
mask.path = myClippingPath.CGPath
myView.layer.mask = mask
