[移动开发]iOS虚线的实现(实现过程与android ＜shape/＞ 类似)

作为Android开发的我，在多年跃跃欲试后，终是干上了iOS！！！

如果用词不对，请帮我指定一下！

今天在实现UI效果的过程中，google一下实现了虚线的效果，做一下笔记：

代码如下（实现了一根虚线）：?

    UIBezierPath *path = [UIBezierPath bezierPath];
    [path moveToPoint:CGPointMake(0, 0)];
    [path addLineToPoint:CGPointMake(0, frame.size.height)];
    
    CAShapeLayer *_shapeLine = [CAShapeLayer layer];
    _shapeLine.frame = CGRectMake(frame.size.width / 2.0, 0, 0.5f, frame.size.height);
    _shapeLine.lineJoin = kCALineJoinRound;
    _shapeLine.lineDashPattern = @[@(2),@(2)];
    _shapeLine.fillColor = [UIColor clearColor].CGColor;
     _shapeLine.strokeColor =[UIColor colorWithHex:0xF0F0F0].CGColor;
    _shapeLine.path = path.CGPath;
    [self.layer addSublayer:_shapeLine];

同时看看一下边的实现：

    UIBezierPath *path4 = [UIBezierPath bezierPathWithRoundedRect:self.bounds cornerRadius: 10];
    
    CAShapeLayer *border = [CAShapeLayer layer];
    border.strokeColor = [UIColor blackColor].CGColor;
    border.fillColor =  [UIColor clearColor].CGColor;;
    border.frame = self.bounds;
    border.lineWidth = 1.f;
    border.lineCap = @"square";
    border.lineDashPattern = @[@2, @2];
    border.path= path4.CGPath;
    [self.layer addSublayer:border];

UIBezierPath是路径，CAShapeLayer是Shape容器，直接绘制到view的layer上，效果如下：

和Android的shape对比一下：
