//Core Raduias
UIView *actionView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 200, 200)];
UIBezierPath *maskPath = [UIBezierPath bezierPathWithRoundedRect:actionView.bounds byRoundingCorners:UIRectCornerTopRight | UIRectCornerBottomRight cornerRadii:CGSizeMake(20, 20)];
CAShapeLayer *maskLayer = [[CAShapeLayer alloc] init];
maskLayer.frame = actionView.bounds;
maskLayer.path = maskPath.CGPath;
actionView.layer.mask = maskLayer;

UIRectCorner枚举值如下:

typedef NS_OPTIONS(NSUInteger, UIRectCorner) {
UIRectCornerTopLeft = 1 << 0,
UIRectCornerTopRight = 1 << 1,
UIRectCornerBottomLeft = 1 << 2,
UIRectCornerBottomRight = 1 << 3,
UIRectCornerAllCorners = ~0UL
};
