隐藏TabBar时ScrollView与VStack中的文本重叠

struct ContentView: View {
    var body: some View {
        GeometryReader { geo in
            ScrollView {
                VStack {
                    // 内容视图
                }
                .frame(width: geo.size.width, height: geo.size.height)
                Spacer()
            }
        }
        .edgesIgnoringSafeArea(.bottom)
    }
}

struct ContentView: View {
    @State private var tabBarHeight: CGFloat = 0.0
    
    var body: some View {
        VStack {
            ScrollView {
                VStack {
                    // 内容视图
                }
            }
            .padding(.bottom, tabBarHeight)
            
            Spacer()
        }
        .onAppear {
            tabBarHeight = UIApplication.shared.windows.first?.safeAreaInsets.bottom ?? 0
        }
    }
}
