iPhone SDK: disable auto creation of dot (.) in text field (or textview)

Question

I've disabled auto-correction type for my text field, and it does not show any other auto-correction,

but it still automatically creates a dot (.) when I press space key twice.

For example, if I write "test" and press space key twice, it automatically changes into "test. "

Anyone knows how to disable this feature?

Thanks a lot.

Answer 1

I found one solution - it uses UITextFieldTextDidChangeNotification because this occurs after the auto-correction applies.

1. Set the delegate for the text field

2. Set up a notification

   - (void) viewDidLoad {
...
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(textFieldDidChange:)
name:UITextFieldTextDidChangeNotification object:tfTitle];
}

3. Then, notification handler
   - (void)textFieldDidChange:(NSNotification *)aNotification
{
if ( [textField.text rangeOfString:@". "].length ) {
// Change text
textField.text = [textField.text stringByReplacingOccurrencesOfString:@". " withString:@" "];
}
}

Perhaps if you hook up a text field delegate and then implement the following method:

-(BOOL)shouldReplaceCharactersInRange:(NSRange)aRage withString:(NSString *)aString

You may be able to check aString for the autocorrected string (maybe @". ") and then just return NO. This will hopefully not allow the @" " to be replaced with @". "
