Question

I check my textfield like this:

-(BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string
{
    if ([subtitleField.text length] == 0)
    {
        searchAddress.hidden = NO;
    }
    else 
    {
        searchAddress.hidden = YES;
    }

   return  YES;   
}

but it works only if I clear textfield by clear key, if I press clear button, it didn’t work.

Answer 1

Implement the [UITextFieldDelegate textFieldShouldClear:] method as well:

- (BOOL)textFieldShouldClear:(UITextField *)textField
{
    searchAddress.hidden = NO;
    return YES;
}
