[MonoTouch] NSUserDefaults

[Kevin Daly]

Sorry, I meant to post this reply to the list, forgot to hit ReplyAll:

 

Convert your string to an NSString before saving it, and use StringForKey
when retrieving it.

 

e.g. NSUserDefaults.StandardUserDefaults["LastName"] = new
NSString(textField.Text);

 

And to retrieve it:

 

If(row == 0)

{

                cell.TextLabel.Text = "Last Name";

                string name =
NSUserDefaults.StandardUserDefaults.StringForKey("LastName")??string.Empty
//1. Note StringForKey 2. The coalesce operator is your friend

                cell.ContentView.AddSubview(TextFieldNormal("your last
name", name, 1, UIKeyboardType.Default));

}

Hi All,

 

has anyone used NSUserDefaults to save application settings ? I have been
looking for code samples without any avail.

 

I want to save the string value for the Settings View. This doesn't seem to
be working. This is what I am trying:

 

To Save the value:

public override void EditingEnded (UITextField textField)

{

var prefs = NSUserDefaults.StandardUserDefaults;

              switch (textField.Tag)

              {

               case 0:

                        prefs["LastName"] = textField.Text;

                        break;

...

 

and to retrieve it:

public override UITableViewCell GetCell (UITableView tableView, NSIndexPath
indexPath)

{

...

            var prefs = NSUserDefaults.StandardUserDefaults;

...

            if (row == 0)

            {

                        cell.TextLabel.Text = "Last Name";

                        string obj = Convert.ToString(prefs["LastName"]);

                        if (obj == null)

                                    obj = "";

                        cell.ContentView.AddSubview (TextFieldNormal("your
last name", obj, 1, UIKeyboardType.Default));

            }

...

 

Please help.

 

Cheers

Manoj.
