@implementation NSString (AbbreviateFirstWord)
-(NSString*)stringByAbbreviatingFirstWord {
   // step 1: Locate the white space.
   NSRange whiteSpaceLoc = [self rangeOfString:@" "];
   if (whiteSpaceLoc.location == NSNotFound)
     return self;
   // step 2: Remove all characters between the first letter and the white space.
   NSRange rangeToRemove = NSMakeRange(1, whiteSpaceLoc.location - 1);
   return [self stringByReplacingCharactersInRange:rangeToRemove withString:@""];
}
