我正在开发一个具有自定义圆角矩形形状的项目,该形状的一侧有一个凹凸,根据我的研究,我必须使用自定义路径绘制一个形状... 但是我这样做不太成功,而且我不明白如何创建它。
要绘制带圆角的自定义形状,
.addArc
是您的朋友。
struct LabelShape: Shape {
let cornerRadius: CGFloat
let tabWidth: CGFloat
func path(in rect: CGRect) -> Path {
var path = Path()
let w = rect.width
let h = rect.height
path.move(to: CGPoint(x: cornerRadius, y: rect.height))
path.addArc(tangent1End: CGPoint(x: w, y: h), tangent2End: CGPoint(x: w, y: 0), radius: cornerRadius)
path.addArc(tangent1End: CGPoint(x: w, y: 0), tangent2End: CGPoint(x: 0, y: 0), radius: cornerRadius)
path.addArc(tangent1End: CGPoint(x: w - tabWidth, y: 0), tangent2End: CGPoint(x: w - tabWidth, y: h), radius: cornerRadius)
path.addArc(tangent1End: CGPoint(x: w - tabWidth, y: cornerRadius * 2), tangent2End: CGPoint(x: 0, y: cornerRadius * 2), radius: cornerRadius)
path.addArc(tangent1End: CGPoint(x: 0, y: cornerRadius * 2), tangent2End: CGPoint(x: 0, y: h), radius: cornerRadius)
path.addArc(tangent1End: CGPoint(x: 0, y: rect.height), tangent2End: CGPoint(x: w, y: h), radius: cornerRadius)
return path
}
}
你可以这样使用:
struct ContentView: View {
var body: some View {
ZStack(alignment: .topTrailing) {
LabelShape(cornerRadius: 10, tabWidth: 110)
.stroke(.red)
.frame(width: 300, height: 100)
HStack(alignment: .firstTextBaseline, spacing: 4) {
Text("01:59:43")
.font(.system(size: 14, weight: .bold))
Text("Hours")
.font(.system(size: 10, weight: .regular))
}
.padding(4)
}
}
}
