Passing a Struct Array through a TableViewCell to another ViewController-CodePudding

I'm new to swift and I've been stuck on this for a while now I'm trying to pass a Struct Array from a tableview cell to another view controller and into another tableview. The cleans way possible, and the entire array, and I'm trying to avoid sending it individually and then adding to a new array in secondViewController. Also the problem I'm facing is I need to send whatever is in that cell. I'm doing this in UIkit and Storyboard Any help would be great, thank you in advice.

Data Models

struct Comment {
    var name: String
    var comment: String
}

struct Model{
    var name: String
    var post: String
    var like: Int
    var comments: [Comment]
    
}

First View Controller / Table View

class MainPage: UIViewController{
    var getInfo: [Model] = [Model(name: "John Wick", post: "My Dog", like: 25, comments: [Comment(name: "Keanu", comment: "Yep I understand")])]
}
extension MainPage: UITableViewDelegate,UITableViewDataSource{
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return getInfo.count
    }
    
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        guard let cell = tableView.dequeueReusableCell(withIdentifier: "NewsFeedViewCell", for: indexPath) as? NewsFeedViewCell else {return
            UITableViewCell()}
        let info = getInfo[indexPath.row]
        cell.nameLabel.text = info.name
        cell.postLabel.text = info.post
        cell.likeLabel.text = "\(info.like) Likes"
        cell.commentsLabel.text = "\(info.comments.count) Comments"
        return cell
    }
    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        guard let vc = storyboard?.instantiateViewController(withIdentifier: "Comment") as? Comment else {return}
        
           navigationController?.pushViewController(vc, animated: true)
    }


    func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
        return 210
    }
    
}

SecondViewController / Table View

class Comment: UIViewController {

    var newFeed = [Model]()
    override func viewDidLoad() {
        super.viewDidLoad()
    }

}

extension Comment: UITableViewDelegate,UITableViewDataSource{
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return newFeed.count
    }

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        guard let cell = tableView.dequeueReusableCell(withIdentifier: "CommentViewCell", for: indexPath) as? CommentViewCell else {return
            UITableViewCell()}
       return cell
    }
    func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
        return 180
        
    }


}

CodePudding user response：

If you want to shop specific cell's data into table of other view controller, then you need to create an object of Model struct rather than its array just like below:

var newFeed: Model?

Next you can assign it value of particular cell before navigation in main did select method as below:

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    guard let vc = storyboard?.instantiateViewController(withIdentifier: "Comment") as? Comment else {return}
    vc.newFeed = getInfo[indexPath.row]
    navigationController?.pushViewController(vc, animated: true)
}

It will assign that cell's data to newFeed Variable and relaod table with that data.

For any question, feel free to ask.
