方法的调用

初始化个view对象

[view borderForColor:[UIColor redColor] borderWidth:2 borderType:UIBorderSideTypeLeft]; [view borderForColor:[UIColor redColor] borderWidth:2 borderType:UIBorderSideTypeRight]; [self.view addSubview:view];

//设置view四周的圆角大小

UIBezierPath *maskPath = [UIBezierPath bezierPathWithRoundedRect:view.bounds byRoundingCorners:UIRectCornerBottomLeft | UIRectCornerTopLeft|UIRectCornerBottomRight cornerRadii:CGSizeMake(10,10)]; CAShapeLayer *maskLayer = [[CAShapeLayer alloc] init]; maskLayer.frame = view.bounds; maskLayer.path = maskPath.CGPath; view.layer.mask = maskLayer;
