需求如上需要在View的左侧切割一个圆角，具体实现如下

 UIBezierPath *maskPath = [UIBezierPath bezierPathWithRoundedRect:self.jiFenBgView.bounds byRoundingCorners:UIRectCornerBottomLeft | UIRectCornerTopLeft cornerRadii:CGSizeMake(15, 15)];
    CAShapeLayer *maskLayer = [[CAShapeLayer alloc] init];
    maskLayer.frame = self.view.bounds;
    maskLayer.path = maskPath.CGPath;
    self.view.layer.mask = maskLayer;

此外苹果还提供了如下的枚举值
