SwiftUI:从屏幕上的CGPoint转换为视图中的CGPoint

import SwiftUI

struct ContentView: View {
    @State private var screenPoint: CGPoint = .zero
    @State private var viewPoint: CGPoint = .zero
    
    var body: some View {
        VStack {
            Text("Screen Point: \(screenPoint)")
            Text("View Point: \(viewPoint)")
        }
        .frame(maxWidth: .infinity, maxHeight: .infinity)
        .background(GeometryReader { geometry in
            Color.clear
                .onAppear {
                    let viewPoint = geometry.convert(screenPoint, from: .global)
                    self.viewPoint = viewPoint
                }
        })
        .onTapGesture {
            let screenPoint = CGPoint(x: 100, y: 100) // 替换为实际的屏幕坐标
            self.screenPoint = screenPoint
            let viewPoint = GeometryReader.convert(screenPoint, from: .global)
            self.viewPoint = viewPoint
        }
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
