I want to preserve the entry of in an iPhone application text field. However, logging and subsequent viewing of the UItextField suggest this string is getting turned into a plain old space...
When I add   to the text field, it goes as single characters until the final semicolon, at which point it disappears from the log message and is seen as simply a single space, thus...
MyApp[17425:20b] Log the string  1234
//I add the semicolon here...
MyApp[17425:20b] Log the string 1234
What I want to do is prevent   from being converted automatically - so that it can later be sent to a website and seen as HTML. Can I even do that with NSString or will it require something else?
Edit: I should have also said that I'd prefer for the UITextField to also display this after I save the data to an array and re-populate the UITextField from the array... I guess it all boils down to whether NSString is really converting this or if it just hides it... Guess I'm not clear on what goes on to auto-magically turn   into a space (at least for display) with NSString...
Edit 2: 8/10/09 Apologies if this is incorrect usage, I couldn't get the interface to allow me to post an "answer" nor could I add a comment...
In answer to Matt's question I will post some code, inside another edit... Also of interest is the logging of the "count" of the string between when the string contained   and when it contained ... What I found interesting is that it seems the count decreases when I "complete" by entering the semicolon... Originally this resulted in the following error because (I think) the count of the string and the count of the range differed as soon as is completed (I'll post code in a bit)... -[NSCFString substringWithRange:]: Range or index out of bounds'
I fixed the crash error by using the string count in the code instead of the range count, but it's still interesting and the "literal" is no longer displayed in the text field...

Edit 4 8/10/09 : posted above code because it wouldn't show up otherwise...
Thanks Matt, interesting indeed... as I was posting my comments it occurred to me that it might be an issue with TextView -- I tried changing a couple of settings in IB, but nothing changed in terms of the "disappearing" My thanks for your time!
