Ios 不完全路径笔划
我正在iOS上创建一个拆分按钮,使用两个相邻的UIButton。像这样: 正如您所见,右按钮左上角有一小口被咬掉,这是不可取的。我想完成中风的那一部分 右按钮使用UIBezierPath作为子层,在按钮周围绘制边框:Ios 不完全路径笔划,ios,swift3,uikit,core-graphics,uibezierpath,Ios,Swift3,Uikit,Core Graphics,Uibezierpath,我正在iOS上创建一个拆分按钮,使用两个相邻的UIButton。像这样: 正如您所见,右按钮左上角有一小口被咬掉,这是不可取的。我想完成中风的那一部分 右按钮使用UIBezierPath作为子层,在按钮周围绘制边框: let borderWidth=CGFloat(4.0) 让borderLayer=CAShapeLayer() var borderFrame=button.bounds.insetBy(dx:borderWidth/2.0,dy:borderWidth/2.0) border
let borderWidth=CGFloat(4.0)
让borderLayer=CAShapeLayer()
var borderFrame=button.bounds.insetBy(dx:borderWidth/2.0,dy:borderWidth/2.0)
borderLayer.frame=borderFrame
borderFrame.origin=CGPoint.zero
borderLayer.path=UIBezierPath(roundedRect:borderFrame,byRoundingCorners:[.topRight、.bottomRight],cornerRadii:radius)。cgPath
borderLayer.lineWidth=borderWidth
borderLayer.fillColor=UIColor.white.cgColor
borderLayer.strokeColor=UIColor.green.cgColor
button.layer.addSublayer(边界层)
如果我使用
borderLayer.path = CGPath(rect: borderFrame, transform: nil)
与UIBezierPath不同,它工作正常。如果我绕过UIBezierPath的左上角,它也可以正常工作
有谁能帮我弄清楚如何按我喜欢的方式画边界吗?
提前谢谢 ,在我的测试中没有:
import UIKit
let path = UIBezierPath(roundedRect: CGRect(x: 0, y: 0, width: 40, height: 40), byRoundingCorners: [.topRight, .bottomRight], cornerRadii: CGSize(width: 10, height: 10))
print(path)
输出:

path.close()
borderLayer.path = path.cgPath
