'UITableView dataSourceはtableView：cellForRowAtIndexPath'からセルを返す必要があります。詳細については、コードを再フォーマットしてください。あまりにも醜い – Geoffroy

セルを返す時間は何回ですか？ – Maulik

http://www.amazon.com/Refactoring-Improving-Design-Existing-Code/dp/0201485672/ref=sr_1_1?s=books&ie=UTF8&qid=1315901566&sr=1-1 – justin

あなたはセルの2つの別々の種類を使用している場合は、次の2つの再利用識別子を使用する必要があります。

customCellが何であるか、それが何時に設定されるのかは不明です。

常に新しいイメージビューをインスタンス化して追加するべきではありません。これにより、複数の画像ビューを互いに重ね合わせて再使用するセルが生じる。画像ビューは、最初にセルを導入し、再利用するときに設定するときに追加する必要があります。星の評価を表示するために5つの画像ビューを使用しているように見えますが、私はユニコードスター文字を使用して考えるとテキストでこれを達成できます。あなたは、コードの//Configure the cell...セクションになっているので、

あなたのコードはcellがnilであるあなたがUITableViewCellオブジェクトを返すために持っているように、この時点で、あなたは、例外を発生させる原因となっているnilを返却され、クラッシュされます。

ドキュメンテーションのセル再利用関数を調べ、パターンをそこに適用します。それは非常に簡単です：

は、サブビューを作成し、何も返されない場合は、セルを作成したり、ペン先からそれをロードし、その識別子
でセルをデキューするためにあなたのindexPath
試みに基づいて再利用識別子を決定しますこの時点
設定でセルとあなたのデキューのサブビューまたは新しく作成されたセル
戻り完成セル
