ナビゲーションコントローラのviewcontrollersの切り替え中にクラッシュしましたか？

まず、スタックオーバーフローのおかげです。私はここで私の問題のための多くの解決策を見つけました。私はナビゲーションビューコントローラ間を移動中にクラッシュしている私のアプリに問題があります一定の期間の後。ナビゲーションコントローラのviewcontrollersの切り替え中にクラッシュしましたか？

私はここで解決策を見つけることを願っています悪いアクセスSubCategoryViewController.m

エラーコードを投稿してください。 –

いくつかのコードは間違いなく助けになるでしょう... –

あなたは私たちにいくつかの洞察力を与えるために相対コードを掲示すべきです。 – samfisher

スタックトレースから、UIViewControllerのライブサイクルの間違ったメソッドでリリースすることによって、いくつかのビューを解放したと思います。

コードなしでこれはちょうど推測です。

それは機能していますか？ SubCategoryView->cid = [cid objectAtIndex:indexPath.row]; あなたは合成CIDが、なぜ使用しないことをSubCategoryViewのプロパティを持っている：
SubCategoryView.cid = [cid objectAtIndex:indexPath.row];

を私は->構造を操作するための有効な演算子ですが、SubCategoryViewがクラスである知っている、私はそれで何の専門家ですあなたはそれをプロパティ呼び出しに変換しようとしましたか？
