XMLを解析し、検索バーがあります。検索しようとすると、次のエラーが発生します。

オブジェクトに対して正規表現のマッチングを行うことはできません<List: 0x888de20>

問題はここにあると思います:

- (void) searchTableView 
{
    [filteredList superclass];
    filteredList = nil;

    filteredList = [[NSMutableArray alloc] initWithArray:app.listArray];
    NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF like[c] %@",[NSString  stringWithFormat:@"%@*",search.text]];
    [filteredList filterUsingPredicate:predicate]; 
}

私はXcodeの初心者です。

これが私のMasterViewControllerクラスです。

@implementation MasterViewController
@synthesize app;
@synthesize detailViewController = _detailViewController;
@synthesize theList;
@synthesize filteredList;
@synthesize search;


- (void)viewDidLoad
{
    [super viewDidLoad];
    app = [[UIApplication sharedApplication] delegate];
    filteredList = [[NSMutableArray alloc] initWithArray:app.listArray];
    [self.tableView reloadData];
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
}
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return 1;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    //return [app.listArray count];
    return [filteredList count];
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil)
    {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
        cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
    }
    theList = [app.listArray objectAtIndex:indexPath.row];
    cell.textLabel.text = theList.znacka;
    cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
    return cell;
}
- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
}

- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];
}

- (void)viewWillDisappear:(BOOL)animated
{
    [super viewWillDisappear:animated];
}

- (void)viewDidDisappear:(BOOL)animated
{
    [super viewDidDisappear:animated];
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{

    return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
}

- (void) searchTableView
{
    [filteredList superclass];
    filteredList = nil;

    filteredList = [[NSMutableArray alloc] initWithArray:app.listArray];
    NSPredicate *predicate = [NSPredicate predicateWithFormat:@"count=%d",[NSString stringWithFormat:@"%@*",search.text]];
    [filteredList filterUsingPredicate:predicate];


}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    DetailViewController *detailView = [[DetailViewController alloc] init];

    theList = [app.listArray objectAtIndex:indexPath.row];

    detailView.theList = theList;

    [self.navigationController pushViewController:detailView animated:YES];
}
- (void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText
{
    [self searchTableView];
    [self.tableView reloadData];
}
- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar
{
    [self searchTableView];
    [search resignFirstResponder];
}
@end

MasterViewController.xibに検索バーがあります。ここに、XMLからの5つのアイテム(theList.znacka)があり、これらのアイテムを検索する必要があります。
