目前我遇到一个小问题。下面的代码将在tableViewHeader的顶部输出一个三角形图层,但我想要反转bazier路径的切割方向。
代码:
let cutDirection = UIBezierPath()
cutDirection.move(to: CGPoint(x: 0, y: 0))
cutDirection.addLine(to: CGPoint(x: headerRect.width, y: 0))
cutDirection.addLine(to: CGPoint(x: headerRect.width, y: headerRect.height))
cutDirection.addLine(to: CGPoint(x: 0, y: headerRect.height - headerCut))
newHeaderLayer.path = cutDirection.cgPath
输出:
结果我正在寻找:
感谢您的帮助!

试试这个:
let cutDirection = UIBezierPath()
cutDirection.move(to: CGPoint(x: 0, y: 0))
cutDirection.addLine(to: CGPoint(x: headerRect.width, y: 0))
cutDirection.addLine(to: CGPoint(x: headerRect.width, y: headerRect.height - headerCut))
cutDirection.addLine(to: CGPoint(x: 0, y: headerRect.height))
newHeaderLayer.path = cutDirection.cgPath

如果我正确地遵循了这一点,你应该交换以下内容:
h1 span{
position:absolute;
}
要:
cutDirection.addLine(to: CGPoint(x: headerRect.width, y: headerRect.height))
cutDirection.addLine(to: CGPoint(x: 0, y: headerRect.height - headerCut))

通过旧学校的方式修复它:在纸上!
<强>解决方案:强>
let cutDirection = UIBezierPath()
cutDirection.move(to: CGPoint(x: 0, y: 0))
cutDirection.addLine(to: CGPoint(x: headerRect.width, y: 0))
cutDirection.addLine(to: CGPoint(x: headerRect.width, y: headerRect.height - headerCut))
cutDirection.addLine(to: CGPoint(x: 0, y: headerRect.height))
cutDirection.close()
newHeaderLayer.path = cutDirection.cgPath
