获取表格单元格的索引路径以更新每个单元格中的按钮

Question

我正在创建一个像instagram这样的应用程序，并在tableview中有一个帖子列表.Posts是通过json从服务器解析下载的。每个帖子在服务器上都有唯一的帖子ID。 每个帖子都有一个喜欢和评论按钮。

PRoblem声明：如何获取特定单元格的post id，以便我可以在按钮和注释按钮操作中使用它。

这就是我在做的事情：

内部文件：PostDataTableVIewCell.swift -

@IBAction func likeBtnPressed(_ sender: AnyObject) {
    if !pressed {
        let image = UIImage(named: "Like-1.png") as UIImage!
        likeBtn.setImage(image, for: .normal)
        pressed = true
    }

    else

    {
//                let buttonPosition:CGPoint = (sender as AnyObject).convert(
//            let indexPath = maincell.feedTable.indexPathForRow(at: buttonPosition)

        let image = UIImage(named: "liked.png") as UIImage!
        likeBtn.transform = CGAffineTransform(scaleX: 0.15, y: 0.15)

        UIView.animate(withDuration: 2.0,
                       delay: 0,
                       usingSpringWithDamping: 0.2,
                       initialSpringVelocity: 6.0,
                       options: .allowUserInteraction,
                       animations: { [weak self] in
                        self?.likeBtn.transform = .identity
            },
                       completion: nil)
        likeBtn.setImage(image, for: .normal)
        pressed = false
        likeUpdateServer()



    }

    }

在更新中的功能 -

 func likeUpdateServer()
{
    let userDefaults = UserDefaults.standard
    let value  = userDefaults.string(forKey: "api_token")
    let api_token : String! = value
    let post_id = userDefaults.string(forKey: "postIDofPost")

    print(api_token)
    print(post_id!)


    var request = URLRequest(url: URL(string: "\(URL_BASE)\(LIKEPOST)")!)
    request.httpMethod = "POST"
    let postString = "api_token=\(api_token!)&&post_key=\(post_id!)"
    print("\(postString)")
    request.httpBody = postString.data(using: .utf8)
    let task = URLSession.shared.dataTask(with: request) { data, response, error in
        guard let data = data, error == nil else {                                                 // check for fundamental networking error
            print("error=\(String(describing: error))")
            print("cant run")
            return
        }

        if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode != 200 {           // check for http errors
            print("statusCode should be 200, but is \(httpStatus.statusCode)")
            print("response = \(String(describing: response))")



        }
        else {
            let responseString = String(data: data, encoding: .utf8)
            print("responseString = \(String(describing: responseString))")
        }
    }
task.resume()
}
