Question

总而言之，我开发了一个应用程序，用于搜索连接到sqlite数据库的表视图。搜索栏被添加到应用程序上并且搜索工作正常，但是当我键入时，我只需要键入字母的STARTING项目出现。这是我的代码，直到现在：

-(void)searchBar:(UISearchBar*)searchBar textDidChange:(NSString*)text
{
    if(text.length == 0)
    {
        isFiltered = FALSE;
    }
    else
    {
        isFiltered = true;
        filteredTableData = [[NSMutableArray alloc] init];

        for (Author* author in theauthors)
        {  //[NSPredicate predicateWithFormat:@"SELECT * from books where title LIKE %@", searchBar.text];
            NSRange nameRange = [author.name rangeOfString:text options:NSCaseInsensitiveSearch];
            NSRange descriptionRange = [author.genre rangeOfString:text options:NSCaseInsensitiveSearch];
            if(nameRange.location != NSNotFound || descriptionRange.location != NSNotFound)
            {
                [filteredTableData addObject:author];
            }
        }
    }

    [self.tableView reloadData];
}

实际上非常简单。我只需要从选项中更改选项文件：NSCaseInsensitiveSearch到选项：NSAnchoredSearch 它就像一个魅力
