键盘偏移在SwiftUI 2中不再起作用

import SwiftUI

struct ContentView: View {
    @State private var isTextFieldFocused = false
    
    var body: some View {
        VStack {
            Text("键盘偏移示例")
                .font(.title)
            
            TextField("输入框", text: .constant(""))
                .textFieldStyle(RoundedBorderTextFieldStyle())
                .padding()
                .focused($isTextFieldFocused)
            
            Spacer()
        }
        .padding()
        .onReceive(NotificationCenter.default.publisher(for: UIResponder.keyboardWillShowNotification)) { notification in
            // 键盘弹出时的处理逻辑
            guard let keyboardFrame = notification.userInfo?[UIResponder.keyboardFrameEndUserInfoKey] as? CGRect else { return }
            
            // 计算键盘高度
            let keyboardHeight = keyboardFrame.height
            
            // 设置视图偏移
            withAnimation {
                // 在这里根据键盘高度调整视图的偏移量
                // 例如：self.viewOffset = keyboardHeight * -0.5
            }
        }
        .onReceive(NotificationCenter.default.publisher(for: UIResponder.keyboardWillHideNotification)) { _ in
            // 键盘隐藏时的处理逻辑
            withAnimation {
                // 在这里恢复视图的原始位置
                // 例如：self.viewOffset = 0
            }
        }
    }
}
