Hi i am searching a clean solution without overwriting drawRect
or stuff like that to create a UIView
with Rounded corners on the Top of the View. My main problem here is to create variable solution if the view is getting resized or something like that.
Is there a clean solution? Apple is this doing too on the first table item. it can't be so hard to do this.
You can do this by setting a mask
on your view's layer:
CAShapeLayer * maskLayer = [CAShapeLayer layer];
maskLayer.path = [UIBezierPath bezierPathWithRoundedRect: self.bounds byRoundingCorners: UIRectCornerTopLeft | UIRectCornerTopRight cornerRadii: (CGSize){10.0, 10.}].CGPath;
self.layer.mask = maskLayer;
IMPORTANT: You should do this in your view's layoutSubviews()
method, so the view has already been resized from the storyboard
In Swift <= 1.2
let maskLayer = CAShapeLayer()
maskLayer.path = UIBezierPath(roundedRect: bounds, byRoundingCorners: .TopLeft | .TopRight, cornerRadii: CGSize(width: 10.0, height: 10.0)).CGPath
layer.mask = maskLayer
Swift 2.x
let maskLayer = CAShapeLayer()
maskLayer.path = UIBezierPath(roundedRect: bounds, byRoundingCorners: UIRectCorner.TopLeft.union(.TopRight), cornerRadii: CGSizeMake(10, 10)).CGPath
layer.mask = maskLayer
Swift 3.x
let maskLayer = CAShapeLayer()
maskLayer.path = UIBezierPath(roundedRect: view.bounds, byRoundingCorners: [.topLeft, .topRight], cornerRadii: CGSize(width: 10, height: 10)).cgPath
layer.mask = maskLayer
