UIPicker in UITextField

Question

I wanna show a picker when I click inside a UITextField. This is my code (which works):

 [super viewDidLoad];
// Picker View dei Tipi
pickerTipo= [[UIPickerView alloc] init];
pickerTipo.showsSelectionIndicator = YES;
UIToolbar* keyboardDoneButtonView = [[UIToolbar alloc] init];

[keyboardDoneButtonView sizeToFit];
UIBarButtonItem* doneButton = [[UIBarButtonItem alloc] 
                               initWithTitle:
                               @"Fine"  style:UIBarButtonItemStyleBordered 
                               target:self 
                               action:@selector(pickerDoneClicked:)];

[keyboardDoneButtonView setItems:[NSArray arrayWithObjects:doneButton, nil]];

self.textTipo.inputAccessoryView = keyboardDoneButtonView;
[self.textTipo resignFirstResponder];
self.textTipo.inputView = pickerTipo;
self.textTipo.delegate  = self;

The picker and the accessory view show correctly. The problem is that the UITextField is still editable, that is I can still typing inside the UITextField. I would that when the picker is shown, no editing is enabled inside the UITextField.

[SOLVED} Following the accepted answer, the right code is :

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range   replacementString:(NSString *)string
{
 if (textField == self.textTipo || textField == self.textStato)
    return NO;
 else
     return YES;
}

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string
{

    if([textField.restorationIdentifier isEqualToString:@"textFieldIdentifier"])
    {
        return NO;
    }
}

Hope it helps.

This is right. I would also return YES or NOT, w.r.t to the textField which is tied to the picker. – gdm Jun 17 '13 at 11:59

Instead of textfied you can use button with a background uiimage view of text field.

try this code:

-(BOOL)textFieldShouldBeginEditing:(UITextField *)textField;
         {
                 if(textField==self.textTipo)
                  {

                        return NO;
                   }
                  else
                  {
                      return YES;
                   }

          }
