iOS Objective C code to make selected corner of a UiView rounded


First import #import <QuartzCore/QuartzCore.h> into your ViewController class. Here is how I set my view in code

UIView *view1=[[UIView alloc]init];
view1.backgroundColor=[UIColor colorWithRed:255/255.0 green:193/255.0 blue:72/255.0 alpha:1.0];
CGRect view1Frame = view1.frame;
view1Frame.size.width = SCREEN_WIDTH*0.97;
view1Frame.size.height = SCREEN_HEIGHT*0.2158;
view1Frame.origin.x = 0;
view1Frame.origin.y = 0.1422*SCREEN_HEIGHT-10;
view1.frame = view1Frame;
[self setMaskTo:view1 byRoundingCorners:UIRectCornerBottomRight|UIRectCornerTopRight];
[self.view addSubview:view1];

Here is the function which does the heavy lifting and rounds off the selected edges which is the Bottom Right and the Top Right edge in our case

- (void)setMaskTo:(UIView*)view byRoundingCorners:(UIRectCorner)corners
    UIBezierPath *rounded = [UIBezierPath bezierPathWithRoundedRect:view.bounds
                                                        cornerRadii:CGSizeMake(20.0, 20.0)];
    CAShapeLayer *shape = [[CAShapeLayer alloc] init];
    [shape setPath:rounded.CGPath];
    view.layer.mask = shape;
