Can the iOS keyboard be programmed not to automatically insert a period for two spaces?

On the iOS platform, I have a UITextField 开发者_如何转开发where I am using the ASCII keyboard layout. I notice (like the keyboard works in other apps) that when I type space + space, a period '.' is inserted into the text field. This is all normal iOS stuff...

But can I configure the text field or the keyboard somehow so that this "two spaces == period" behavior is turned off?

One possible solution (albeit not a perfect one) has been posted here ... http://www.mailinglistarchive.com/phoenix-iphone-developer-group@googlegroups.com/msg00037.html
