テキストと写真とテキストのみを表示するセルでテーブルビューを作成しようとしています。私は2つのカスタムtableviewcellsを作成しましたが、私はそれらを表ビューで混在させたいときに一度に表示することができます。基本的には、画像に画像がない場合は、TextFeedCellをロードして、そうであればphotoFeedCellをロードします。複数のカスタムUITableViewCells
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
if FeedTVCellWithPhoto().post?.imageContentName != "" {
let photoFeedCell = tableView.dequeueReusableCellWithIdentifier(FeedTVController().cellId, forIndexPath: indexPath) as! FeedTVCellWithPhoto
photoFeedCell.post = posts[indexPath.section]
return photoFeedCell
}
else {
let textFeedCell = tableView.dequeueReusableCellWithIdentifier(FeedTVController().textCellId, forIndexPath: indexPath) as! FeedTVCellText
textFeedCell.post = posts[indexPath.section]
return textFeedCell
}
}
助けていただければ幸いです。
アップデート1：
の両方が登録されている：
tableView?.registerClass(FeedTVCellWithPhoto.self, forCellReuseIdentifier: cellId)
tableView?.registerClass(FeedTVCellText.self, forCellReuseIdentifier: textCellId)
私は条件文なしでそれらを実装する際にこれらのカスタムセルの両方が、自分自身に取り組みます。問題は、条件付きで（上記のように）それらを実装すると、イメージを持たないポストを取得しますが、まだ空のimageViewsが挿入されてしまいます。

これはiOSでも問題ないので、間違ったセルIDやセクション/行数を入力したか、コードに論理エラーがあります。私は、あなたがストーリーボードと 'FeedTVController（）'のセル識別子をチェックし、デバッガを使ってコードをチェックしてロジックをチェックすることをお勧めします。 –
コードは正常です。あなたの変数の内容を再確認してください。 'post'。 Interface Builder/storyboardの識別子を確認してください。 – MirekE
.xibファイルを使用している場合は、それらをテーブルビューに登録する必要があります。 –
