正しく入力された の読み込みと表示が完了するとUITableView、アプリケーションがクラッシュし、次の出力が表示されます。
*** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayM objectAtIndex:]: index 14 beyond bounds [0 .. 13]'
テーブルビューに影響を与える可能性のあるすべての可変配列の内容を確認しましたが、それらはすべて[mutableArray count];. [0 .. 13]最も奇妙な部分は、14 個のインデックスの配列を持つアプリ全体のどこにもないため、値を設定できる単一の可変配列がないことです。
はUITableView期待どおりに孤独なセルを返し、1 回だけ呼び出しますcellForRowAtIndexPath( を使用して確認NSLog)。ビューが表示されてから約0.5秒から1秒後にクラッシュしますNSRangeException。
クラス内の唯一の変更可能な配列UITableViewがチェックされ[mutableArray count];、生成された唯一のセルである 1 だけが返されます。
コンソールの読み出しが配列の内容や場所を示しておらず、強調表示されている行がメイン メソッドの自動解放の SIGBART にすぎない場合、これをデバッグするにはどうすればよいですか?
