我正在尝试使用Shape、Geometry reader和Path在SwiftUI中绘制一个圆形,我希望阴影正好位于圆形下方,但阴影偏移了,并且我似乎无法将它绘制到应该处:
struct ContentView: View {
var body: some View {
return GeometryReader { geometry in
VStack(alignment: .center) {
BackgroundRing()
.stroke(Color.red, style: StrokeStyle(lineWidth: geometry.size.width < geometry.size.height ? geometry.size.width / 12.0 : geometry.size.height / 12))
.padding()
.shadow(color: .gray, radius: 1.0, x: 0.0, y: 0.0)
}
}
}
}
struct BackgroundRing : Shape {
func path(in rect: CGRect) -> Path {
var path: Path = Path()
let radiusOfRing: CGFloat = (rect.width < rect.height ? rect.width/2 - rect.width / 12 : rect.height/2 - rect.height / 12)
path.addRelativeArc(center: CGPoint(x: rect.width/2, y: rect.height/2),
radius: radiusOfRing,
startAngle: Angle(radians: 0.0),
delta: Angle(radians: Double.pi * 2.0 ))
return path
}
}
