Answer 1

You haven't defined what you mean by a special character, and you seem to want to replace it with a space, not remove it.

NSArray * comps = [stringTitle componentsSeparatedByString:@"_"]

NSString * result = nil;
for(NSString *s in comps)
{
   if(result)
   {
      result = [result stringByAppendingFormat:@" %@",[s capitalizedString];
   }
   else
   {
       result = [s capitalizedString];
   }
}

If you have other special characters that you want to replace, then use

-componentsSeparatedByCharactersInSet:
