排序数据

Question

NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];
  NSEntityDescription *entity = [NSEntityDescription entityForName:entityName inManagedObjectContext:globalManagedObjectContext];
  [fetchRequest setEntity:entity];
   NSSortDescriptor *sortByName = [[NSSortDescriptor alloc] initWithKey:@"Name" ascending:YES];
  [fetchRequest setSortDescriptors:[NSArray arrayWithObject:sortByName]];
  fetchResults = [NSMutableArray arrayWithArray:[globalManagedObjectContext executeFetchRequest:fetchRequest error:nil]];
  [fetchRequest release];
  [sortByName release];
  return fetchResults;

跟上案例敏感性.大写在上面.
