How to display two arrays in two different cells in UITableView using swift3

Question

I am trying to display two arrays in two different cells in a table view but it doesn't works , can any one help me to solve this problem , I am using Xcode8 and Swift3 , and this is my TableView code .

this is how I want to display the two arrays :

row1 = aaa

row2 = 11111

row3 = bbb

row4 = 2222

row5 = cccc

row6 = 3333

row7 = ddd

row8 = eee

row9 = fff

My code :

 import UIKit

 class _CellsTableViewController: UITableViewController {

var array1 = [String]()
var array2 = [String]()

override func viewDidLoad() {
    super.viewDidLoad()

    array1 = ["aaa","bbb","ccc","ddd","eee","fff"]

    array2 = ["11111","22222","33333"]
}

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

// MARK: - Table view data source

override func numberOfSections(in tableView: UITableView) -> Int {
    // #warning Incomplete implementation, return the number of sections
    return 1
}

override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {



        return array1.count + array2.count


}


override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

    if indexPath.row == 0 {

     let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)

   cell.textLabel?.text = array1[indexPath.row]

        return cell

    }
    else {

    let cell = tableView.dequeueReusableCell(withIdentifier: "cell1", for: indexPath)

    cell.textLabel?.text = array2[indexPath.row]

    return cell

    }

 }


 }

Why the heck do you think if indexPath.row == 0 would do this? Seems a basic programming issue. — meaning-matters

ya surely you get , bz if you are using if indexPath.row == 0 { , it is the one index and at the same time your array count is 9 but you load different ok simple this is if indexPath.row == 0 { or if indexPath.section == 0 { — Anbu.Karthik

make a single array with combination of two and then reload table. See the following code,

let array1 = ["aaa","bbb","ccc","ddd","eee","fff"]
let array2 = ["11111","22222","33333"]
var arrayAllItems = [String]()
for i in 0..<max(array1.count, array2.count){
    if array1.count > i{
        arrayAllItems.append(array1[i])
    }
    if array2.count > i{
        arrayAllItems.append(array2[i])
    }
}

Reload table with array arrayAllItems

I don't understand why you need to do this. But you code should be:

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

    var index = indexPath.row/2;

    if(index<array1.count %% index<array2.count)
    {
        if (indexPath.row % 2 == 0){
            let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)
            cell.textLabel?.text = array1[index]
            return cell
        }
        else {

            let cell = tableView.dequeueReusableCell(withIdentifier: "cell1", for: indexPath)
            cell.textLabel?.text = array2[index]
            return cell
        }
    }
    else {
        var isFirst
        if(index>=array1.count)
        {
            index = indexPath.row - array1.count;
            isFirst = false
        }else
        {
            index = indexPath.row - array2.count;
            isFirst = true
        }
        if(isFirst)
        {
            let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)
            cell.textLabel?.text = array1[index]
            return cell
        }else
        {
            let cell = tableView.dequeueReusableCell(withIdentifier: "cell1", for: indexPath)
            cell.textLabel?.text = array2[index]
            return cell
        }
    }

 }

But I don't test this code.
