but i don't know how to make a comment box where users can also leave comment , thanks
This Is My CommentViewController:
var tableView: UITableView = UITableView()
var dataArray: Array<JSON>!
override func viewDidLoad() {
super.viewDidLoad()
self.title = "Comments"
if #available(iOS 11.0, *) {
navigationController?.navigationBar.prefersLargeTitles = true
navigationController?.navigationItem.largeTitleDisplayMode = .automatic
let attributes = [
NSAttributedString.Key.foregroundColor : navigationBarTextColor, NSAttributedString.Key.font: UIFont(name: "SFUIText-Medium", size: 34),
]
navigationController?.navigationBar.largeTitleTextAttributes = attributes as [NSAttributedString.Key : Any]
} else {
// Fallback on earlier versions
}
// Check if Post have comments
if(self.dataArray.count == 0){
self.view.backgroundColor = UIColor(red: 216 / 255, green: 216 / 255, blue: 216 / 255, alpha: 1.0)
let label = UILabel(frame: CGRect(x: (UIScreen.main.bounds.width/2)-100, y: (UIScreen.main.bounds.height/2)-50, width: 200, height: 50))
label.text = "No Comments"
label.font = UIFont(name: "SFUIText-Regular", size: 18)
label.textAlignment = NSTextAlignment.center
self.view.addSubview(label)
}
else{
self.setupTable()
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func getDateFromString(String:String) -> String{
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
let dateObj = dateFormatter.date(from: String)
dateFormatter.dateFormat = "yyyy-MM-dd"
return dateFormatter.string(from: dateObj!)
}
func setupTable(){
tableView = UITableView(frame: UIScreen.main.bounds, style: UITableView.Style.plain)
tableView.delegate = self
tableView.dataSource = self
tableView.register(UINib(nibName: "commentViewCell", bundle: nil), forCellReuseIdentifier: "cell")
tableView.frame.size.height = UIScreen.main.bounds.height - 64
tableView.bounces = false
tableView.allowsSelection = false
self.view.addSubview(self.tableView)
}
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
return self.dataArray.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! commentViewCell
cell.commentText.text = String(htmlEncodedString: dataArray[indexPath.row]["content"].stringValue)
cell.name.text = String(htmlEncodedString:dataArray[indexPath.row]["name"].stringValue)
cell.date.text = getDateFromString(String: dataArray[indexPath.row]["date"].stringValue)
return cell
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return UITableView.automaticDimension
}
func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
return UITableView.automaticDimension
}
}

Answer 1

So you have a "tableView" field where all comments are shown.
As Joakim Danielson advices, you should add UITextView to the bottom of your screen.
Because the table view can be too long to fit the screen height, it probably will be scrolled, so it's easier to add this text view as a cell.
So you can do this in a following way:
Change the size of tableView for leaving the comment at the end:
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
return self.dataArray.count + 1
}
Add the cell with text view, let's name it LeaveCommentCell
Return the LeaveCommentCell instance as the last cell:
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{
if indexPath.row == self.dataArray.count { // this is the last row
let cell = tableView.dequeueReusableCell(withIdentifier: "AddCommentCell", for: indexPath) as! LeaveCommentCell // your new cell
return cell
}
let cell = tableView.dequeueReusableCell(withIdentifier: "ShowCommentCell", for: indexPath) as! commentViewCell // please note identifiers should differ
cell.commentText.text = String(htmlEncodedString: dataArray[indexPath.row]["content"].stringValue)
cell.name.text = String(htmlEncodedString:dataArray[indexPath.row]["name"].stringValue)
cell.date.text = getDateFromString(String: dataArray[indexPath.row]["date"].stringValue)
return cell
}
Add a button (e.g. with text "Post") to LeaveCommentCell, subscribe for event when it's pressed, get comment text and send it to server.
