This might help you instead of the view below use a uitableview with custom cells Each custom cell having a label ...and add a cell if and only if u have a valid string in a textfeild..set userinteraction=NO and set some backgroung color to match ur view..
just put that string in the uilabel in the custom cell...thats it..

With these it helps I want to clear all values on a form where the control is a label and its name starts with "label" , Try to use this method:
code :
public void ClearLabel(Control control)
{
   if (control is Label)
   {
       Label lbl = (Label)control;
       if (lbl.Text.StartsWith("label"))
           lbl.Text = String.Empty;

   }
   else
       foreach (Control child in control.Controls)
       {
           ClearLabel(child);
       }

}

should help you out It's a bug #1192 in the latest version 1.7.0, for phones that don't support power-of-two textures. I've changed how the textures are created, but missed one case.
The issue happen only on the phone with a crappy GPU :) Yes crappy, because OpenGL ES 2 specification says that power-of-two textures are mandatory. Guess what, Adreno 200 series (and maybe others) doesn't support them, but claim they are GLES 2.
code :
cd python-for-android
git clean -dxf
git pull origin master
Validating Textbox is not Empty with Labels and hiding label once text is entered

Validating Textbox is not Empty with Labels and hiding label once text is entered

may help you . I have a simple inventory application that I am working on to help myself learn C#. I have a registration Windows Form that will add a user to a database so that they can login to the application. It works. However I am now working on adding some textbox validation. I have three text boxes that will populate a label beside them if they are empty. However, I cannot figure out how to get the label to be null or hide after text is entered. Any suggestions? , I am not exactly sure if I follow your comment:
code :
public Form1() {
  InitializeComponent();
  ClearLabels();
  SetLabels();
}

private void createButton_Click(object sender, EventArgs e) {
  string statusString = "";

  if (!ValidUserInput(out statusString)) {
    lblStatus.Text = statusString;
  }
  else {
    ///OleDbConnection con = new OleDbConnection(@"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=|DataDirectory|FAMDatabase.accdb");
    //OleDbCommand fcmd = new OleDbCommand("INSERT INTO Login([UserName],[Password])" + "values(@username,@password)", con);
    //fcmd.Parameters.AddWithValue("@username", newUserTextBox.Text);
    //fcmd.Parameters.AddWithValue("@password", newPasswordTextBox.Text);
    //con.Open();
    //int i = fcmd.ExecuteNonQuery();
    //con.Close();
    MessageBox.Show("User Successfully Created","", MessageBoxButtons.OK, MessageBoxIcon.Information, MessageBoxDefaultButton.Button1);
    //this.Close();
  }
}

private bool ValidUserInput(out string message) {
  ClearLabels();
  if (string.IsNullOrEmpty(newUserTextBox.Text)) {
    reqName.Text = ("Please enter a User Name");
    message = "UserName can not be blank!";
    return false;
  }
  if (string.IsNullOrEmpty(newPasswordTextBox.Text)) {
    reqPW.Text = ("Please enter a Password");
    message = "Password can not be blank!";
    return false;
  }
  if (string.IsNullOrEmpty(newPasswordTextBox2.Text)) {
    reqPW2.Text = ("Please enter a Password ");
    message = "Password verification can not be blank!";
    return false;
  }
  if (newPasswordTextBox.Text != newPasswordTextBox2.Text) {
    reqPW.Text = ("Passwords Do Not Match");
    reqPW2.Text = ("Passwords Do Not Match");
    message = "Password must match!";
    return false;
  }
  message = "Valid User Input";
  return true;
}

private void ClearLabels() {
  reqName.Text = "";
  reqPW.Text = "";
  reqPW2.Text = "";
  lblStatus.Text = "";
}

private void SetLabels() {
  ClearLabels();
  if (string.IsNullOrEmpty(newUserTextBox.Text)) {
    reqName.Text = "Please enter a User Name";
  }
  if (string.IsNullOrEmpty(newPasswordTextBox.Text)) {
    reqPW.Text = "Please enter a Password";
  }
  if (string.IsNullOrEmpty(newPasswordTextBox2.Text)) {
    reqPW2.Text = "Please enter a Password";
  }
  lblStatus.Text = "Enter userName and password";
}

private void newUserTextBox_TextChanged(object sender, EventArgs e) {
  if (string.IsNullOrEmpty(newUserTextBox.Text)) {
    reqName.Text = "Please enter a User Name";
  }
  else {
    reqName.Text = "";
  }
}

private void newPasswordTextBox_TextChanged(object sender, EventArgs e) {
  if (string.IsNullOrEmpty(newPasswordTextBox.Text)) {
    reqPW.Text = "Please enter a Password";
  } else {
    reqPW.Text = "";
  }
}

private void newPasswordTextBox2_TextChanged(object sender, EventArgs e) {
  if (string.IsNullOrEmpty(newPasswordTextBox2.Text)) {
    reqPW2.Text = "Please enter a Password";
  } else {
    reqPW2.Text = "";
  }
}

will be helpful for those in need Cells in a tableview are reused, so a cell at an index path that is not visible could have values from a completely different cell. If you want to get all the cells that are currently visible on the screen, you could use tableView.visibleCells docs to get all the cell that are currently on screen and extract data from there.
Alternatively, you could choose to not implement cell reuse and make your table view static. You can do this in Interface Builder, or you could also choose to create all the cells up front and return your pre-made cells in tableView(_:cellForRowAt:). Note that a setup like this is okay for small datasets, but has terrible performance for larger sets so be aware that this might not be the best way to do things. It really depends on your situation. This method of doing things would end up looking a bit like this:
code :
var cells = [UITableViewCell]()

override func viewDidLoad() {
  // do all kinds of stuff

  for field in fields { // or whatever else mechanism you use as your datasource
    let cell = UITableViewCell()
    // configure your cell
    cells.append(cell)
  }
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
  return cells[indexPath.row]
}
