Swift-畫虛線、虛線圓

程式碼如下:

case .LayerType_XuXian_Circle:
            self.title = "畫虛線"
            //畫虛線
             let dotteShapLayer = CAShapeLayer()
             let mdotteShapePath = CGPathCreateMutable()
             dotteShapLayer.fillColor = UIColor.clearColor().CGColor
             dotteShapLayer.strokeColor
= UIColor.orangeColor().CGColor dotteShapLayer.lineWidth = 2.0 CGPathAddEllipseInRect(mdotteShapePath, nil, CGRectMake(100.0, 150.0, 200.0, 200.0)) dotteShapLayer.path = mdotteShapePath let arr :NSArray = NSArray(array: [10,5]) dotteShapLayer.lineDashPhase
= 1.0 dotteShapLayer.lineDashPattern = arr as? [NSNumber] view.layer.addSublayer(dotteShapLayer) break case .LayerType_XuXian_Line: self.title = "畫虛線直線" //畫虛線 let dotteShapLayer = CAShapeLayer() let mdotteShapePath = CGPathCreateMutable() dotteShapLayer.fillColor
= UIColor.clearColor().CGColor dotteShapLayer.strokeColor = UIColor.orangeColor().CGColor dotteShapLayer.lineWidth = 2.0 CGPathMoveToPoint(mdotteShapePath, nil, 20, 100) CGPathAddLineToPoint(mdotteShapePath, nil, 20, 200) CGPathAddLineToPoint(mdotteShapePath, nil, 200, 200) dotteShapLayer.path = mdotteShapePath let arr :NSArray = NSArray(array: [10,5]) dotteShapLayer.lineDashPhase = 1.0 dotteShapLayer.lineDashPattern = arr as? [NSNumber] view.layer.addSublayer(dotteShapLayer) break

效果如下:
