How to change particular cell color in ios swift3

Question

I have an String array like [1,2,3,4,5]. I am displaying this array in tableview. My Question is If I want to change the color of 3rd cell only, How can I compare 3rd element with array in ios swift?

Answer 1

on your tableview delegate method based on the condition change the color what you want

override func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
cell.backgroundColor = indexPath.row == 2 ? .red : yellow //or use cell.contentView.backgroundColor = = indexPath.row == 2 ? .red : yellow
}

if you want to change the array contains 3 condition based then use like

override func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
cell.backgroundColor = yourArrayName[indexPath.row] == "3" ? .red : yellow //or use cell.contentView.backgroundColor = = yourArrayName[indexPath.row] == "3" ? .red : yellow
}

okay we go with alternate way

 override func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
   cell.backgroundColor = .yellow
  if let index = yourArrayName.index(of: "3") {
   cell.backgroundColor = indexPath.row == index ? .red : yellow 
  }
}

Answer 2

You can check the condition inside your cellforrow function like this too :

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "ExampleCellIndentifier", for: indexPath) as! ExampleCell

        if indexPath.row == 2{
            // Do your modification on the 3rd cell item
            cell.backgroundColor = .red
        }

        return cell
    } 

Answer 3

I just applied condition under cellForRowAt

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "TextFieldInTableViewCell") as! myProfieTabelViewCellTableViewCell
    if indexPath[1] % 2  == 0{
         cell.backgroundColor = #colorLiteral(red: 0.9088078997, green: 0.9088078997, blue: 0.9088078997, alpha: 1)
        print(indexPath[1])
    }
    else{
         cell.backgroundColor = #colorLiteral(red: 1.0, green: 1.0, blue: 1.0, alpha: 1.0)
    }
    cell.selectionStyle = .none
    return cell
}
