UIAlertView and Core Data

Hi to all of stackoverflow, i'm Italian so, i'm sorry for my bad English... :D

i tried to create a simple tableView for listing a few names and a number... all with core data.

- (void)tableView:(UITableView *)tableView 
didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
  Track *track = [[self fetchedResultsController] objectAtIndexPath:indexPath];
  if(YES == self.editing) {
      UIAlertView* alert = [[UIAlertView alloc] initWithTitle:@"Modifica nome" message:@"Prego, inserire di seguito il nuovo nome:" delegate:self cancelButtonTitle:@"Annulla" otherButtonTitles:@"Salva", nil];
      newname = [[alert addTextFieldWithValue:track.name label:@"Nome"] text];
      [alert textField].autocorrectionType = UITextAutocorrectionTypeNo;
      [alert show];
      [alert release];
      [selectedTrack release];
  } else {
      UIAlertView* alert = [[UIAlertView alloc] initWithTitle:@"Aggiungi minchiate" message:@"Sei sicuro di voler aggiungere una michiata a" delegate:self cancelButtonTitle:@"Annulla" otherButtonTitles:@"Salva", nil];
      newname = [[alert addTextFieldWithValue:track.trackAbstract label:@"Minchiate"] text];
      [alert textField].autocorrectionType = UITextAutocorrectionTypeNo;
      [alert show];
      [alert release];
      [selectedTrack release];
  }
}

I want to send the value of the textfield to my attributes that i've created first... Need I put the code in this method?!

- (void)alertView:(UIAlertView *)alertView willDismissWithButtonIndex:(NSInteger)buttonIndex
{
    if (buttonIndex != [alertView cancelButtonIndex])
    {
        //HERE?!
    }
}

And how i can set a new value on a core data at开发者_如何学运维tribute? ANY help is appreciated... Thanks in advance!

Yes, you would put the code to grab the value from the text field in the alertView:willDismissWithButtonIndex: method. Assuming you've created a model class for that entity (which I assume you have, as I see a class called Track in your code), you can set the value of an attribute by using dot syntax:

Track.someAttribute = newValue

Or without dot syntax, it would be [Track setSomeAttribute:newValue].

Also, note that UIAlertView's addTextFieldWithValue:label: is an undocumented method, which isn't a problem if this is an app you're planning to create just for yourself, but using it in an app submitted to the App Store will likely get it rejected.
