how to set cornerRadius for only bottom-left,bottom-right and top-left corner of a UIView?

Question

Is there a way to set cornerRadius for only bottom-left,bottom-right and top-left corner of a UIView?

I tried the following, but it ended up making the view disappear. Is there anything wrong with the code below?

    UIBezierPath *maskPath;     maskPath = [UIBezierPath bezierPathWithRoundedRect:view.bounds byRoundingCorners:(UIRectCornerBottomLeft | UIRectCornerBottomRight) cornerRadii:CGSizeMake(20.0, 20.0)];     CAShapeLayer *maskLayer = [[CAShapeLayer alloc] init];     maskLayer.path = maskPath.CGPath;     view.layer.mask = maskLayer;

You can do it like this:

UIBezierPath *maskPath = [UIBezierPath bezierPathWithRoundedRect:self.viewOutlet.bounds byRoundingCorners:(UIRectCornerTopLeft | UIRectCornerBottomLeft | UIRectCornerBottomRight) cornerRadii:CGSizeMake(10.0, 10.0)];  CAShapeLayer *maskLayer = [[CAShapeLayer alloc] init]; maskLayer.frame = self.view.bounds; maskLayer.path  = maskPath.CGPath; self.viewOutlet.layer.mask = maskLayer; 

Update:
If You need border just create another CAShapeLayer and add it to view's layer as sublayer. Like this (place this code below upper code):

CAShapeLayer *borderLayer = [[CAShapeLayer alloc] init]; borderLayer.frame = self.view.bounds; borderLayer.path  = maskPath.CGPath; borderLayer.lineWidth   = 4.0f; borderLayer.strokeColor = [UIColor blackColor].CGColor; borderLayer.fillColor   = [UIColor clearColor].CGColor;  [self.viewOutlet.layer addSublayer:borderLayer]; 

In swift 3.0 like this:

let maskPath = UIBezierPath.init(roundedRect: self.viewOutlet.bounds, byRoundingCorners:[.topLeft, .bottomLeft], cornerRadii: CGSize.init(width: 10.0, height: 10.0)) let maskLayer = CAShapeLayer() maskLayer.frame = self.viewOutlet.bounds maskLayer.path = maskPath.cgPath self.viewOutlet.layer.mask = maskLayer
