This is the work-around that I did because I could not make do with
NSNumberFormatter.

I've been programming the mac since 1987 pretty much full-time. so I promise
you, I am not confused at all about what a number is, and isn't...

I think you missed the earlier messages. You are probably looking at the
converter that I wrote as a work-around, which is basically a numeric string
formatter.

I think you missed the previous message, where someone else made your same
incorrect assumption, only to have that cleared up by Jens Alfke. Jens picked
up that I was actually using an NSNumber with the NSNumberFormatter. Please
look at the comment from Jens Alfke , and the three lines of code below, they
should clear that up for you.
> only that what you seem to think of as a number is
I promise you I know what a number is...
This got answered a while back...

Here's the original piece of code that you must have missed, please read the
code carefully.
I added two comments in the code in case you missed the NSNumber line.
// <--- NSUInteger (look for these below)
// <--- NSNumber (look for these below)
//
+---------+---------+---------+---------+---------+---------+---------+---------+
- (void)awakeFromNib
{
// I have already run a routine to strip all non digits by this time
NSString *strippedNumber = @"1234567890";
NSString *phoneNumber;
NSString *format;
format = @"(###) ###-####";
phoneNumber = [BHUtility bhFormatNumberString:strippedNumber
withFormat:format];
}
//
+---------+---------+---------+---------+---------+---------+---------+---------+
//
+---------+---------+---------+---------+---------+---------+---------+---------+
+ (NSString *)unusable_bhFormatNumberString:(NSString *)aNumberString
withFormat:(NSString *)aFormat
{
// THIS METHOD DOES NOT WORK, WITH OR WITHOUT THE NEXT LINE
// YIELDS INCORRECT RESULTS : @"(1234567890) -"
[NSNumberFormatter
setDefaultFormatterBehavior:NSNumberFormatterBehavior10_0];
NSNumberFormatter *numberFormatter = [[[NSNumberFormatter alloc] init]
autorelease];
// NSFormatter *numberFormatter = [[[NSNumberFormatter alloc] init]
autorelease];
[numberFormatter setFormat:aFormat]; // specify just positive values
format
NSUInteger theInt = [aNumberString intValue]; //
<--- NSUInteger
NSNumber *theNum = [NSNumber numberWithInt:theInt]; // <--- NSNumber
NSString *theString = (NSString *)[numberFormatter stringFromNumber:theNum];
NSLog(@"[4625] theString = %@", theString);
return theString;
//
+---------+---------+---------+---------+---------+---------+---------+---------+
}
//
+---------+---------+---------+---------+---------+---------+---------+---------+
