CAShapeLayer具有边框和填充颜色和圆角

如何使用CAShapeLayer绘制具有边框颜色，边框宽度和填充颜色的线条？CAShapeLayer具有边框和填充颜色和圆角

下面是我尝试过，但它只有永远的蓝色......

self.lineShape.strokeColor = [UIColor blueColor].CGColor; 
self.lineShape.fillColor = [UIColor greenColor].CGColor; 
self.lineShape.lineWidth = 100; 
self.lineShape.lineCap = kCALineCapRound; 
self.lineShape.lineJoin = kCALineJoinRound; 
UIBezierPath* path = [UIBezierPath bezierPath]; 
[path moveToPoint:self.lineStart]; 
[path addLineToPoint:self.lineEnd]; 
self.lineShape.path = path.CGPath;

self.lineShapeBorder = [[CAShapeLayer alloc] init]; 
    self.lineShapeBorder.zPosition = 0.0f; 
    self.lineShapeBorder.strokeColor = [UIColor blueColor].CGColor; 
    self.lineShapeBorder.lineWidth = 25; 
    self.lineShapeBorder.lineCap = kCALineCapRound; 
    self.lineShapeBorder.lineJoin = kCALineJoinRound; 

    self.lineShapeFill = [[CAShapeLayer alloc] init]; 
    [self.lineShapeBorder addSublayer:self.lineShapeFill]; 
    self.lineShapeFill.zPosition = 0.0f; 
    self.lineShapeFill.strokeColor = [UIColor greenColor].CGColor; 
    self.lineShapeFill.lineWidth = 20.0f; 
    self.lineShapeFill.lineCap = kCALineCapRound; 
    self.lineShapeFill.lineJoin = kCALineJoinRound; 

// ... 

    UIBezierPath* path = [UIBezierPath bezierPath]; 
    [path moveToPoint:self.lineStart]; 
    [path addLineToPoint:self.lineEnd]; 
    self.lineShapeBorder.path = self.lineShapeFill.path = path.CGPath;

这是我的最终解决方案 – jjxtra

如果图层的fillColor属性设置为nil或透明以外的内容，该层将填补其路径。

如果你设置图层的lineWidth到数大于零，并设置其strokeColor比nil或透明以外的内容，该层将行程中的路径。

如果你设置的所有这些属性，该层将填补和行程中的路径。它填充后绘制中风。

图层的路径必须实际上包含某个区域才能填充任何内容。在您的文章中，您设置如下路径：

UIBezierPath* path = [UIBezierPath bezierPath]; 
[path moveToPoint:self.lineStart]; 
[path addLineToPoint:self.lineEnd]; 
self.lineShape.path = path.CGPath;

该路径包含单个线段。它没有包含任何区域，所以图层没有任何可填写的内容。

我更新我的问题与我目前的代码... – jjxtra

@PsychoDad我已经更新了我的答案。 –

所以我需要让我的路径成为一个多边形呢？ – jjxtra

在Swift 3.扩展方法UIView。

// Usage: 
self.btnGroup.roundCorner([.topRight, .bottomRight], radius: 4.0, borderColor: UIColor.red, borderWidth: 1.0) 

// Apply round corner and border. An extension method of UIView. 
public func roundCorner(_ corners: UIRectCorner, radius: CGFloat, borderColor: UIColor, borderWidth: CGFloat) { 
    let path = UIBezierPath.init(roundedRect: self.bounds, byRoundingCorners: corners, cornerRadii: CGSize(width: radius, height: radius)) 

    let mask = CAShapeLayer() 
    mask.path = path.cgPath 
    self.layer.mask = mask 

    let borderPath = UIBezierPath.init(roundedRect: self.bounds, byRoundingCorners: corners, cornerRadii: CGSize(width: radius, height: radius)) 
    let borderLayer = CAShapeLayer() 
    borderLayer.path = borderPath.cgPath 
    borderLayer.lineWidth = borderWidth 
    borderLayer.strokeColor = borderColor.cgColor 
    borderLayer.fillColor = UIColor.clear.cgColor 
    borderLayer.frame = self.bounds 
    self.layer.addSublayer(borderLayer) 
}
