为什么我只能在TableView Swift中显示我的第一部分？

Question

I have created two arrays called section one and two to feed in their data to my table.

let Sec1 = ["Section" , "One"]
let Sec2 = ["Section", "Two"]

And I have create an array called sectionTitles which contains the name of my sections.

let sectionTitles = ["Section1" , "Sectoin2"]

And then I have the following delegate table view functions :

public func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String?{
    return sectionTitles[section]

    }
    public func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int{
        switch section {
        case 0 :
            return Sec1.count
        default:
            return Sec2.count

        }

    }
    public func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell{
        let cell = challengeTable.dequeueReusableCell(withIdentifier: cellID) as! CustomisedCell
        cell.selectionStyle = .none

        switch indexPath.section {
        case 0:
            cell.CAChallengeTitle.text = Sec1[indexPath.row]
            cell.CAChallengeDescription.text = "\(Sec1[indexPath.row])  "
            cell.CAChallengeButt.tag = indexPath[1]
            cell.CAChallengeButt.setTitle("I am interested >", for: .normal)
            print("Done with sectoin 0")
        default:
            cell.CAChallengeTitle.text = Sec2[indexPath.row]
            cell.CAChallengeDescription.text = "\(Sec2[indexPath.row])  "
            cell.CAChallengeButt.tag = indexPath[1]
            cell.CAChallengeButt.setTitle("I am interested >", for: .normal)
            print("Done with sectoin 1")

        }
       return cell

    }

    public func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat{
        let height : CGFloat  = 60
        return height
    }

But in the end I only get to present the fist section only. Any idea where am I making my mistake ?

Answer 1

You haven't implemented the numberOfSections data source method.

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

Without this, the table assumes 1 section.

Answer 2

You have to implement numberOfRowsInSection method of tableView in case you are using only static sactions then you have to return the count of sections in numberOfRowsInSection method. otherwise, store all the sections in an array and return Array.count
