Question

我创建了一个包含自定义单元格的TableView控制器，并填充了MySQL数据库中的数据。一切都很好。

我添加了一个搜索栏，搜索效果也很好。但是，当我选择搜索结果时，它会将我带到错误的详细视图（例如，我点击“Cookies”，它会将我发送到“苹果”的详细视图）。我错过了我的.m文件中的内容吗？这是我的代码：

的.m

- (int)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{

    if (tableView == self.searchDisplayController.searchResultsTableView) {
        return [searchResults count];



    } else {
        return [Strains count];

    }


}


- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *strainTableIdentifier = @"StrainTableCell";

    StrainTableCell *cell = (StrainTableCell *)[tableView dequeueReusableCellWithIdentifier:strainTableIdentifier];
    if (cell == nil) 


        cell = [[StrainTableCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:strainTableIdentifier];



        NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"StrainTableCell" owner:self options:nil];
        cell = [nib objectAtIndex:0];

    if (tableView == self.searchDisplayController.searchResultsTableView) {

        cell.titleLabel.text = [[searchResults objectAtIndex:indexPath.row] objectForKey:@"Title"];
        cell.descriptionLabel.text = [[searchResults objectAtIndex:indexPath.row] objectForKey:@"Description"];
        cell.ratingLabel.text = [[searchResults objectAtIndex:indexPath.row] objectForKey:@"Rating"];


        NSLog(@"%@", searchResults);
    } else {
        cell.titleLabel.text = [[Strains objectAtIndex:indexPath.row] objectForKey:@"Title"];
         cell.descriptionLabel.text = [[Strains objectAtIndex:indexPath.row] objectForKey:@"Description"];
         cell.ratingLabel.text = [[Strains objectAtIndex:indexPath.row] objectForKey:@"Rating"];


    }

    {

    } 


return cell;

}



- (void)filterContentForSearchText:(NSString*)searchText scope:(NSString*)scope
{
    NSPredicate *resultPredicate = [NSPredicate 
                                    predicateWithFormat:@"SELF contains[cd] %@",
                                    searchText];

    searchResults = [Strains filteredArrayUsingPredicate:resultPredicate];


}

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

    return YES;
}


- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    StrainDetailViewController *detailViewController = [[StrainDetailViewController alloc]
                                                        initWithNibName:@"StrainDetailViewController" bundle:nil];
    detailViewController.title = [[Strains objectAtIndex:indexPath.row] objectForKey:@"Title"];
    detailViewController.strainDetail = [Strains objectAtIndex:indexPath.row];
              [self.navigationController pushViewController:detailViewController animated:YES];


    }

Answer 1

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
StrainDetailViewController *detailViewController = [[StrainDetailViewController alloc]                                                 initWithNibName:@"StrainDetailViewController" bundle:nil];
if (self.searchDisplayController.searchResultsTableView) {

      detailViewController.title = [[searchResults objectAtIndex:indexPath.row] objectForKey:@"Title"];
      detailViewController.strainDetail = [searchResults objectAtIndex:indexPath.row];

} else {

     detailViewController.title = [[Strains objectAtIndex:indexPath.row] objectForKey:@"Title"];
     detailViewController.strainDetail = [Strains objectAtIndex:indexPath.row];
}

[self.navigationController pushViewController:detailViewController animated:YES];
}

在表视图中放置搜索栏。选择结果会导致错误的细节视图
