Angular Radius Using UIBezierPath

Question

I am trying to get around my viewing angles using UIBezierPath. I only need to round the upper right and upper left.

I used the following code

 -(void)setMaskOnView:(UIView *)givenView
  {
UIBezierPath *maskPath = [UIBezierPath bezierPathWithRoundedRect:givenView.bounds byRoundingCorners: (UIRectCornerTopLeft|UIRectCornerTopRight) cornerRadii:CGSizeMake(10.0, 10.0)];
CAShapeLayer *maskLayer = [[CAShapeLayer alloc] init];
maskLayer.frame = givenView.bounds;
maskLayer.path  = maskPath.CGPath;
givenView.layer.mask = maskLayer;
} 

But my TopRight Corner is not a round.

I used

UIRectCornerAllCorners

But it's not around my right corners

Any thing I miss?

Answer 1

I propose a different approach. Download the image with rounded top corners and set it as content CALayer. Set this layer as the mask of your layer. Update the size of the mask layer in layoutSubivewsthis view or viewDidLayoutSubviewsthis view controller.

contenst

CALayer *maskLayer = [[CALayer alloc] init];
UIImage *maskImage = [UIImage imageNamed:@"mask_image.png" inBundle:[NSBundle mainBundle] compatibleWithTraitCollection:nil];
maskLayer.contents = (__bridge id _Nullable)(maskImage.CGImage);

mainLayer.mask = maskLayer

[EDIT]

CAShapeLayer , , , . UITableViewCell, layoutSubviews. (MyTableCell ):

@interface MyTableCell ()

@property (nonatomic, strong) CAShapeLayer *maskLayer;

@end

@implementation MyTableCell

- (void)awakeFromNib
{
    self.maskLayer = [[CAShapeLayer alloc] init];
    self.layer.mask = self.maskLayer;
}

- (void)layoutSubviews
{
    [super layoutSubviews];
    self.maskLayer.path = [self maskPath].CGPath;
}

- (UIBezierPath *)maskPath
{
    return [UIBezierPath bezierPathWithRoundedRect:self.bounds byRoundingCorners: (UIRectCornerTopLeft|UIRectCornerTopRight) cornerRadii:CGSizeMake(10.0, 10.0)];

}

@end

.h

@interface UIView (custom)

- (UIView *)setRoundedCorners:(UIRectCorner)corners withRadius:(CGFloat)radius;

@end

.m

@implementation UIView (custom)

    - (UIView *)setRoundedCorners:(UIRectCorner)corners withRadius:(CGFloat)radius
    {
        UIBezierPath *maskPath = [UIBezierPath bezierPathWithRoundedRect:self.bounds
                                                       byRoundingCorners:corners
                                                             cornerRadii:CGSizeMake(radius, radius)];

        CAShapeLayer *maskLayer = [CAShapeLayer layer];

        maskLayer.frame = self.bounds;

        maskLayer.path = maskPath.CGPath;

        self.layer.mask = maskLayer;

        return self;
    }
@end

:

[YOURVIEW setRoundedCorners:UIRectCornerBottomLeft | UIRectCornerBottomRight | UIRectCornerTopLeft | UIRectCornerTopRight withRadius:15];
