How to prevent UITableView from reuse custom cells Swift

Question

In my App I use UITableView with custom cells.

for each cell I implement function to create it, and call these functions in cellForRow.

this is an code example from project :

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {


    if indexPath.row == CellsTypes.profileImageCell.rawValue {

        return createIntroCell()
    }

    else if indexPath.row == CellsTypes.fullNameCell.rawValue {

        return createUserNameCell()

    }

    else if indexPath.row == CellsTypes.emailCell.rawValue {

        return createEmailCell()


    }
    else  {

        return createPasswordCell()

    }}

and these are the creation functions :

func createUserNameCell() -> TextFieldTableViewCell {

    let fullNameCell = self.tableView.dequeueReusableCellWithIdentifier("text-field-cell") as! TextFieldTableViewCell
    fullNameCell.awamirTextFieldNib.setNormalTextFieldCellContent("Full Name")
    fullNameCell.awamirTextFieldNib.textFieldContent.tag = CellsTypes.fullNameCell.rawValue
    fullNameCell.awamirTextFieldNib.textFieldContent.returnKeyType = .Next
    fullNameCell.awamirTextFieldNib.textFieldContent.delegate = self
    return fullNameCell
}

func createEmailCell() -> TextFieldTableViewCell {

    let emailCell = self.tableView.dequeueReusableCellWithIdentifier("text-field-cell") as! TextFieldTableViewCell
    emailCell.awamirTextFieldNib.setNormalTextFieldCellContent("Email")
    emailCell.awamirTextFieldNib.textFieldContent.tag = CellsTypes.emailCell.rawValue
    emailCell.awamirTextFieldNib.textFieldContent.returnKeyType = .Next
    emailCell.awamirTextFieldNib.textFieldContent.delegate = self
    return emailCell
}
 func createPasswordCell() -> TextFieldTableViewCell {

    let textFieldCell = self.tableView.dequeueReusableCellWithIdentifier("text-field-cell") as! TextFieldTableViewCell
    textFieldCell.awamirTextFieldNib.setPasswordCellContent("Password")
    textFieldCell.awamirTextFieldNib.textFieldContent.tag = CellsTypes.passwordCell.rawValue
    textFieldCell.awamirTextFieldNib.textFieldContent.returnKeyType = .Next
    textFieldCell.awamirTextFieldNib.textFieldContent.delegate = self

    return textFieldCell
}

the problem is if I reload the tableview the content of cells changed because of the reusablity of the cells. i.e: after reload the tableview the content of the first cell become in the second cell, and the content of the sencond on became in the first cell!!

how can I prevent tableview from reusable the cells?!

Thanks.

Answer 1

Try using a different identifier for each of the cell types, so dont use "text-field-cell" for each one, make one "full name", "password" etc. not sure how you are going about creating your cells, but if you are using the registerNib or registerClass, you will need to register it for each different identifier

self.tableView.registerNib(UINib(nibName: "CustomCell", bundle: nil), forCellReuseIdentifier: "full name")
self.tableView.registerNib(UINib(nibName: "CustomCell", bundle: nil), forCellReuseIdentifier: "password")
self.tableView.registerNib(UINib(nibName: "CustomCell", bundle: nil), forCellReuseIdentifier: "email")

Don't use the default UITableView and fight the reuse of cells, it's really embedded in it's behaviour.

Try to adapt your code so it works well with reusing cells, or if that's really impossible, you'd have to write your own custom table view I guess (but I don't recommend that at all)
