Answer 1

Try this thing.

NSString *str = @"above string"; //load above string here
NSArray * firstArry = [str componentsSeparatedByString:@"#"];
NSMutableArray *secondArry = [[NSMutableArray alloc] init]; //Will hold the # titles
NSMutableDictionary *dict = [[NSMutableDictionary alloc] init]; //Will hold the strings related to # title
for(NSString firstArryStr in firstArry)
  {
      NSArray *tempArry = [firstArryStr componentsSeparatedByString@"\n"];
      NSMutableArray *titleStingsArry = [[NSMutableArray alloc] init];
      for (int i=0; i< [tempArry count];i++) {
            if (i==0) {
                NSString *title = [tempArry  objectAtIndex:i];
                [secondArry addObject:title];
                [dict setValue:titleStingsArry  forKey:title];
            } else {
                [titleStingsArry  addObject:[tempArry  objectAtIndex:i]];
            }
      } 
  }

Now you have secondArry for section and dictionary of array for rows in sections.

P.S. Please ignore syntax error as I’m not using mac machine right now and take care of memory management also.
