How to switch custom xib cell when didSelect call? - swift

Question

I have a tableView with 2 custom xib cells. I want to switch the custom cell when user tapped it also adjust the cell height. How do I achieve it? I tried to use container view but then the height would be the same. I want to know if it is possible to do it with two xib for tableView cell? Thank you.
var isContactView: Bool = true
override func viewDidLoad() {
super.viewDidLoad()
tableView.delegate = self
tableView.dataSource = self
tableView.register(UINib(nibName: "ContactTableViewCell", bundle: nil), forCellReuseIdentifier: "contactCell")
tableView.register(UINib(nibName: "DetailTableViewCell", bundle: nil), forCellReuseIdentifier: "detailCell")
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
//if ContactTableViewCell return 40
//if DetailTableViewCell return 150
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 1
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
//by default the cell view is ContactTableViewCell.
//When user tapped the cell it will change to DetailTableViewCell.
if isContactView {
let cell = tableView.dequeueReusableCell(withIdentifier: "contactCell", for: indexPath) as! ContactTableViewCell
//do something...
} else {
let cell = tableView.dequeueReusableCell(withIdentifier: "detailCell", for: indexPath) as! DetailTableViewCell
//do something...
}
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
//not sure how to change the xib in here.
//if cell view is ContactTableViewCell
cell view = tableView.dequeueReusableCell(withIdentifier: "detailCell", for: indexPath) as! DetailTableViewCell
isContactView = false
tableView.reloadData()
//else
cell view = tableView.dequeueReusableCell(withIdentifier: "contactCell", for: indexPath) as! ContactTableViewCell
isContactView = true
tableView.reloadData()
}

There are 2 cases:
If there's just single cell to be viewed, then just put the following code in didSelect:
isContactView = !isContactView
tableView.reloadData()
If there are multiple cells in which the condition is to be applied. Please put a key in your data model.
For example:
testArr is the array of objects that you are displaying in tableview. Then keep a key, say isContactView in this model. And put the login based upon this key.
Like in case of cellForRow:
if testArr[indexpath.row].isContactView {
let cell = tableView.dequeueReusableCell(withIdentifier: "contactCell", for: indexPath) as! ContactTableViewCell
//do something...
} else {
let cell = tableView.dequeueReusableCell(withIdentifier: "detailCell", for: indexPath) as! DetailTableViewCell
//do something...
}
And in didselect:
isContactView = !testArr[indexPath.row].isContactView
