swiftui - 如何在 onTapGesture 中获取本地点击位置？

Question

有一些渲染图像，需要确定相对于图像的点击位置。看似简单，却找不到答案

  var body: some View {
    VStack {
      Image(uiImage: drawRectangle()) // some rendered image
        .onTapGesture {
          // print(x, y)?
        }

Answer 1

找到了这个解决方案:

        .gesture(
            DragGesture(minimumDistance: 0, coordinateSpace: .global)
                .onChanged { value in
                  self.position = value.location
                }
                .onEnded { _ in
                  self.position = .zero
                }
        )

设置 minimumDistance: 0将立即调用 onChanged
