在SwiftUI中处理UITextView的UIResponder

class TextViewDelegate: NSObject, UITextViewDelegate {
    func textViewDidChange(_ textView: UITextView) {
        // 处理文本改变事件
    }
    
    func textViewDidBeginEditing(_ textView: UITextView) {
        // 处理开始编辑事件
    }
    
    func textViewDidEndEditing(_ textView: UITextView) {
        // 处理结束编辑事件
    }
    
    // 其他UITextViewDelegate方法...
}

struct TextView: UIViewRepresentable {
    @Binding var text: String
    
    func makeUIView(context: Context) -> UITextView {
        let textView = UITextView()
        textView.delegate = context.coordinator
        return textView
    }
    
    func updateUIView(_ uiView: UITextView, context: Context) {
        uiView.text = text
    }
    
    func makeCoordinator() -> TextViewDelegate {
        return TextViewDelegate()
    }
}

struct ContentView: View {
    @State private var text: String = ""
    
    var body: some View {
        VStack {
            TextView(text: $text)
                .frame(height: 200)
            
            Text("输入的文本：\(text)")
        }
    }
}
