How to change particular UITableviewcell colour in iOS swift4 - ios

Question

I have two arrays like
names = ["Gopal", "Harish", "Kartik","Raj", "Vishal", "Manoj", "James"]
StoredNames = ["kartik", "Vishal", "James"]
I am displaying names Array into tableview. But My Task is if names array contains StoredNames array elements, I need to change that particular cell colour.Could anyone guide me to do this task.I am using is code. but unable to compare with StoredNames array.
override func tableView(_ tableView: UITableView, willDisplay cell:UITableViewCell, forRowAt indexPath: IndexPath) {
cell.backgroundColor = .yellow
if let index = names.index(of: "kartik") {
cell.backgroundColor = indexPath.row == index ? .green : .white
}
return cell
}
After edit:
func filterRowsForSearchedText(_ searchText: String) {
filteredModels = models.filter({( model : Contact) -> Bool in
return model.name.lowercased().contains(searchText.lowercased())||model.number.lowercased().contains(searchText.lowercased())
})
contactsTableView.reloadData()
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = contactsTableView.dequeueReusableCell(withIdentifier: "ContactsTableViewCell", for: indexPath) as! ContactsTableViewCell
let model: Contact
if searchController.isActive && searchController.searchBar.text != "" {
model = filteredModels[indexPath.row]
} else {
model = models[indexPath.row]
}
cell.nameLabel.text = model.name
cell.numberLabel.text = model.number
return cell
}
func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
if storedNumberArr.contains(numberArr[indexPath.row]) {
//Name is there, color it
cell.backgroundColor = .green
} else {
// Color for non existance.
cell.backgroundColor = .white
}
}

Answer 1

You can use contains(element). Keep in mind that else statement is necessary because of reusable functionality. Also variable names should be camelCase.
let names = ["Gopal","Harish","Kartik","Raj","Vishal","Manoj","James"]
let storedNames = ["kartik","Vishal","James"]
if storedNames.contains(names[indexPath.row]) {
//Name is there, color it
cell.backgroundColor = .green
} else {
// Color for non existance.
cell.backgroundColor = .white
}
As suggested by dahiya_boy, if you want to compare string discarding their cases you can replace above if-condition by this :
if storedNames.map({ $0.lowercased()}).contains(names[indexPath.row].lowercased()) {

Please use this in cellforrow at indepath
if(indexPath.row % 2 == 0) {
cell.backgroundColor = UIColor.init(rgb: 0xebebeb)
} else{
cell.backgroundColor = UIColor.init(rgb: 0xdcdcdc)
}
