- formatting a number from 123456789 to 123 456 789

I didn't see this part of your original question. NSNumberFormatter can do that, too.
#import <Foundation/Foundation.h>
int main (int argc, const char * argv[]) {
NSArray *a = [NSArray arrayWithObjects:
[NSNumber numberWithUnsignedLongLong: 12],
[NSNumber numberWithUnsignedLongLong: 1234],
[NSNumber numberWithUnsignedLongLong: 12345678],
[NSNumber numberWithUnsignedLongLong: 1234567890123],
nil];
NSNumberFormatter *nf = [NSNumberFormatter new];
[nf setNumberStyle: NSNumberFormatterDecimalStyle];
[nf setGroupingSeparator: @" "];
for(NSNumber *n in a) {
NSString *aString = [nf stringFromNumber:n];
NSLog(@"%@ => %@ => %@", n, aString, [nf numberFromString:
aString]);
}
return 0;
}
