私はまだプログラミングの初心者です。私はiOS Devクラスの最終プロジェクトを行っています.それは基本的なアプリを構築することです. 私は数日間これを完了する方法を理解しようとしてきましたが、次々と問題が発生しています。明日が期限なので、今、私は時間に追われています。私のアプリは、シボレー車のリストと各車名の横に写真を表示することになっています。これは、Table View Controller で行われます。私の問題は、セルをクリックしたときにあります。車の情報が空白のラベル。たとえば、「馬力」というラベルがあり、その横に車の実際の馬力が表示されるはずです。実際の馬力を表示する代わりに、空白のラベルが表示されます。不足しているものはありますか？私が使用したコードを皆さんに見せる方法はありますか? 私には「1」の評判しかありません。
どんな助けでも大歓迎です。
これはテーブルビューコントローラーからのものです：
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"carTableCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
cell.textLabel.text = [_carModels objectAtIndex: indexPath.row];
cell.imageView.image = [UIImage imageNamed:[_carImages objectAtIndex: indexPath.row]];
return cell;
}
これが私のdetailViewController.mです
