iOS6、iOS5 の私のコードは正常に動作しますが、xcode5 をインストールした後、iOS7 でアプリを実行します。[alert show] の行でアプリがクラッシュします。エラー情報は次のとおりです。Thread 1:EXC_BAD_ACCESS (code=1, address=0x3)

どうしてか分かりません。誰でも私を助けることができます。ありがとうございました！

私のコード:

- (void) whetherRememberDialog{

dialogFlag = WHETHER_REMEMBER_DIALOG;

    NSString *titleInfo = @"Whether remember?";
    NSString *cancelInfo = @"cancel";
    NSString *okInfo = @"Ok";

    UIAlertView *storeQuesitonDialog = [[UIAlertView alloc] initWithTitle:titleInfo
                                                                  message:nil
                                                                 delegate:self
                                                        cancelButtonTitle:cancelInfo
                                                        otherButtonTitles:okInfo, nil];
    //[storeQuesitonDialog show];
    [storeQuesitonDialog performSelectorOnMainThread:@selector(show) withObject:nil waitUntilDone:YES]; // In this line the app is crash this codes 
    [storeQuesitonDialog release];

}

ARC のため、iOS 7 でオブジェクトを手動で解放することはできません。オブジェクトの割り当て解除は ARC が管理するため、オブジェクトを解放しないでください。これにより、ARC がオブジェクトを解放した後に解放し、エラーをスローする可能性があります。また、アラートビューを解除した場合、画面にどのように表示されることになっていますか? リリースを削除すると、これが修正される場合があります。
