copied!<p>I think that you have something like this to setup your text field:</p> <pre><code> self.citys = @[@"Buenos Aires", @"Bahia Blanca", @"Azul",@"Pigue"]; self.namePicker = [[UIPickerView alloc] init]; self.namePicker.delegate = self; self.namePicker.dataSource = self; self.namePicker.showsSelectionIndicator = YES; self.accessoryView = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)]; UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(onNameSelection)]; [self.accessoryView setItems:[NSArray arrayWithObject:doneButton]]; self.textField.inputView = self.namePicker; self.textField.inputAccessoryView = self.accessoryView; </code></pre> <p>And something like this to set the text when the user finish the selection:</p> <pre><code>- (void) onNameSelection{ NSInteger row = [self.namePicker selectedRowInComponent:0]; self.textField.text = [self.citys objectAtIndex:row]; [self.textField resignFirstResponder]; } </code></pre> <p>So... You don't need the action EditingChanged, because you know when the <code>textfield.text</code> is changed.</p> <p>Maybe you also have something like this to change the text while the user select row in the picker:</p> <pre><code>- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component{ self.textField.text = [self.citys objectAtIndex:row]; } </code></pre> <p>Again, you know when the <code>textfield.text</code> is changed. </p> <p>So... Because <strong>YOU</strong> are the responsible of the changes on the <code>textfield.text</code> <strong>YOU</strong> are the responsible of call the function associated to the EditingChanged action.</p>
