Question

hope that somebody can help me, thank you already anyway. So realized an expanding Tableview cell (when i tap the cell it open with more detail) and now i want to adjust the height the cell, how i have to do? because before the cell i want to put an image with a description and i want the cell not on the top but at the end of my controller, i tried to put an imagine in my view controller but i have a error in my code, what code i need for adjust the height and put an image with description before the cell?

class PROVAViewController: UITableViewController {

    var tableViewData = [cellData]()

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.

        tableViewData = [cellData(opened: false, title: "Title1", sectionData: ["Cell1","Cell2","Cell3"]),
                         cellData(opened: false, title: "Title1", sectionData: ["Cell1","Cell2","Cell3"]),
                         cellData(opened: false, title: "Title1", sectionData: ["Cell1","Cell2","Cell3"]),
                         cellData(opened: false, title: "Title1", sectionData: ["Cell1","Cell2","Cell3"])]
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    override func numberOfSections(in tableView: UITableView) -> Int {
        return tableViewData.count
    }

    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        if tableViewData[section].opened == true {
            return tableViewData[section].sectionData.count + 1
        } else {
            return 1
        }

    }

    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let dataIndex = indexPath.row - 1
        if indexPath.row == 0 {
            guard let cell = tableView.dequeueReusableCell(withIdentifier: "cell") else {return UITableViewCell()}
            cell.textLabel?.text = tableViewData[indexPath.section].title
            return cell

        } else {
            guard let cell = tableView.dequeueReusableCell(withIdentifier: "cell") else {return UITableViewCell()}
            cell.textLabel?.text = tableViewData[indexPath.section].sectionData[dataIndex]
            return cell
        }
    }
    override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        if indexPath.row == 0 {
            if tableViewData[indexPath.section].opened == true {
                tableViewData[indexPath.section].opened = false
                let sections = IndexSet.init(integer: indexPath.section)
                tableView.reloadSections(sections, with: .none) // play around with it(cosa significa non lo so, vedi video)

            }else{
                tableViewData[indexPath.section].opened = true
                let sections = IndexSet.init(integer: indexPath.section)
                tableView.reloadSections(sections, with: .none)

            }
        }

        }

    }

Answer 1

Set the top, bottom, leading, and trailing for the label, also set number of lines to 0 .set the tableview height to UITableViewAutomaticDimension . This will make the label and cell grow according to the content.

Answer 2

I am not sure if understood you question Correctly:

Your cell has and imageView with a UILabel next to it with dynamic content.

You can use the following logic.

Step:- 1 Make sure the row size is changed at both the places as shown on Screen shots:

Step:- 2 Drag an imageView and label into cell and get it done with following constraints:

Hope this helps.
