Question

您好我如何在tableView中搜索？我对NSMutableArray使用XML解析。我想搜索时出错。我想对细胞进行详细搜索。

您可以使用此代码进行搜索：

-(void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText
{
    NSArray * searchResults = [haberlistesi filteredArrayUsingPredicate: [NSPredicate predicateWithFormat: @"al CONTAINS[c] %@ OR baslik CONTAINS[c] %@", searchedString, searchedString]];

   //Use this searchResults array as DataSource for your table view and reload the table view, For instance:
   haberlistesi = [searchResults mutableCopy];

   [self.tableView reloadData];
}

快乐编码.. :)
