如何创建一个在我的应用程序视图中显示评论的函数(Swift-JSON)

import UIKit

func displayComments() {
    // 从服务器获取评论数据的URL
    let url = URL(string: "https://example.com/comments.json")!

    // 发起网络请求获取JSON数据
    URLSession.shared.dataTask(with: url) { (data, response, error) in
        if let error = error {
            print("Error: \(error.localizedDescription)")
            return
        }

        guard let data = data else {
            print("No data received")
            return
        }

        do {
            // 解析JSON数据
            let comments = try JSONSerialization.jsonObject(with: data, options: []) as? [[String: Any]]

            // 处理评论数据
            if let comments = comments {
                for comment in comments {
                    if let username = comment["username"] as? String,
                       let text = comment["text"] as? String {
                        // 在应用程序视图中显示评论
                        DispatchQueue.main.async {
                            // 创建评论视图并添加到应用程序界面
                            let commentView = UILabel(frame: CGRect(x: 0, y: 0, width: 200, height: 50))
                            commentView.text = "\(username): \(text)"
                            commentView.numberOfLines = 0
                            commentView.sizeToFit()
                            // 将评论视图添加到你的应用程序视图中
                            // ...
                        }
                    }
                }
            }
        } catch {
            print("Error parsing JSON: \(error.localizedDescription)")
        }
    }.resume()
}
