SwiftUI强制肖像显示在除一个视图之外的所有视图上

import SwiftUI

struct ContentView: View {
    var body: some View {
        ZStack {
            // 背景视图
            Color.blue.edgesIgnoringSafeArea(.all)
            
            // 需要隐藏肖像的视图
            VStack {
                Text("Hello, World!")
                    .foregroundColor(.white)
                    .font(.largeTitle)
                Image(systemName: "person.crop.circle")
                    .foregroundColor(.white)
                    .font(.largeTitle)
                    .opacity(0) // 设置透明度为0，使其不可见
            }
            
            // 肖像视图
            Image("portrait")
                .resizable()
                .frame(width: 100, height: 100)
                .position(x: UIScreen.main.bounds.width / 2, y: UIScreen.main.bounds.height / 2)
        }
    }
}

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