iOS 6 の Xcode 4.2 で iPhone アプリに問題があります。アプリは動作しており、下部のバーにダウンロード ボタンがあります。シミュレーターでこれを押すと、正常に動作し、彼の仕事が行われます。アプリの同じビルドを使用してデバイスで同じボタンを押すと、クラッシュします。コンソールに警告が表示されません。しかし、私はこのクラッシュレポートを持っており、私のコードはその下にあります。これがデバイスで機能しない理由が本当にわかりません。

ダウンロード メソッドに NSLog ステートメントを追加して、dinfo が nil かどうかを確認することから始めます。次に、downloadButton とツールバーも有効であることを確認します。

NSLog(@"downloadButton: %@", [downloadButton description])

trySetUpDownload メソッドでオブジェクトを保持する方法がわかりません。

自動解放オブジェクトではない場合は、試すことができます

DownloadInfo *dinfo=[[self trySetUpDownload] 保持]; それはあなたを助けるかもしれません..
