Request for member 'uitextfield' in something not a structure or union?

working through several other problems I have found myself at this point. I have learnt alot about the stuff I am trying to do but this one I am completely stumped on.

I am writing a textfield format for a login I would like to have on my app, and because apple don't have anything that resembling a textfield mask I have decided to write my own custom cell that looks like it has a mask on it but all I will be doing is concatenating textfields in the background.

However I have struck a problem. I am trying to call textField:shouldChangeCharactersInRange:replacementString: of a UITextField in my Subclassed UITableViewCell as outlined in my code below. However Im receiving Request for member 'uitextfield' in something not a structure or union error... any help would be appreciated.

////.h

@interface RegisterDeviceViewController : UIViewController <UITableViewDelegate, UITextFieldDelegate> {

    RegisterDeviceViewController *registerDeviceViewController;

    //UITextFields for the registration cell
    UITextField *regFieldOne;
    UITextField *regFieldTwo;
    UITextField *regFieldThree;
    UITextField *regFieldFour;

    UITableViewCell *myRegistrationField;
    UITableViewCell *mySubmitButton;

}
//UITextFields for the registration cell
@property (nonatomic, retain) IBOutlet UITextField *regFieldOne;
@property (nonatomic, retain) IBOutlet UITextField *regFieldTwo;
@property (nonatomic, retain) IBOutlet UITextField *regFieldThree;

    }

        return cell;

        cell.regFieldOne.delegate = self; //This is where the error is.
    }
    return cellButton;

regFieldDone is not a member of cell (table view cell). Its a member of your class register device view controller. If you are trying to set regFieldDone's delegate to self, then change that statement to regFieldDone.delegate = self

EDIT: You can directly set all text field's delegate to RegisterDeviceViewController (file owner) from the xib file.

You have only set regFieldDone's delegate to self, what about other textField's delegate? So when you edit other textField's, the delegate method will not get called.

You should notice that shouldChangeCharactersInRange... method gets called while editing regFieldDone and doesnt while editing other textField's. I advice you to set all textField's delegate to self, either programatically or from xib file.
