ios - xcode 搜索栏崩溃尝试输入内容

#pragma Search Methods

-(void)filterContentForSearchText:(NSString *)searchText scope:(NSString *)scope
{
    NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF beginswith[c] %@",searchText];
    _AramaSonuclari = [_TarifAdi filteredArrayUsingPredicate:predicate];
    
}

-(BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString
{
    [self filterContentForSearchText:searchString scope:[[self.searchDisplayController.searchBar scopeButtonTitles] objectAtIndex:[self.searchDisplayController.searchBar selectedScopeButtonIndex]]];
    return YES;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    
    // Return the number of rows in the section.
    if (tableView == self.searchDisplayController.searchResultsTableView)
    {
        return [_AramaSonuclari count];
    }
    else
    {
        return _TarifAdi.count;
    }
    
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    
    TableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"TableViewCell" forIndexPath:indexPath];
    
    cell.tag = indexPath.row;
    //cell.imageView.image = nil;
    
    if (tableView == self.searchDisplayController.searchResultsTableView)
    {
        cell.TitleLabel.text = _AramaSonuclari[indexPath.row];
    }
    else
    {
        cell.TitleLabel.text = _TarifAdi[indexPath.row];
    }

    return cell;
 }

我们的问题是，当我们尝试在搜索栏中输入任何字符时，应用程序崩溃，我们确实调试了我们的代码，没有错误。我们认为，我们的问题出在 Storyboard连接上；我还添加了一张图片。当我们删除 searchBar 引用导出时，我们可以输入一些东西，但当然代码在没有连接的情况下无法工作。

您还必须将单元格注册到 searchdisplaycontroller。

Important: You must register a class or nib file using the registerNib:forCellReuseIdentifier: or registerClass:forCellReuseIdentifier: method before calling this method.

在 View 中加载

如果您在代码中创建单元格

 [self.searchDisplayController.searchResultsTableView registerClass:[TableViewCell class] 
    forCellReuseIdentifier:@"IdentifierForCell"];

如果你在 nib 中创建单元格

  [self.searchDisplayController.searchResultsTableView registerNib:[UINib nibWithNibName:@"CellNibName" bundle:nil]
                                        forCellWithReuseIdentifier:@"IdentifierForCell"];
