Где утечка памяти в моем UITableViewController?

0 голосов
/ 08 июня 2011

Представление таблицы работает нормально, однако, когда я покидаю представление и возвращаюсь к нему во второй раз, я получаю утечку памяти. Вероятно, что-то в viewDidLoad просто не уверен.

Я запускаю инструмент утечки и получаю следующее уведомление:

когда я нажимаю на первую строку в расширенном представлении, я получаю: 

  14 CFNetwork URLConnectionClient::_clientDidFinishLoading(URLConnectionClient::ClientConnectionEventQueue*)
  15 CFNetwork URLConnectionClient::ClientConnectionEventQueue::processAllEventsAndConsumePayload(XConnectionEventInfo<XClientEvent, XClientEventParams>*, long)
  16 CFNetwork URLConnectionClient::processEvents()
  17 CFNetwork MultiplexerSource::perform()

Я вижу, что большая часть вашего оператора готова к утечке, например, в методе viewDidUnload вы не освобождаете ни одного члена экземпляра должным образом.

вам нужно вызвать release для объекта, который вы либо выделили, init илисохранить. 

 (void)viewDidUnload {
    // Relinquish ownership of anything that can be recreated in viewDidLoad or on demand.
    // For example: self.myOutlet = nil;

    [remoteRecipientItems release];
    remoteRecipientItems = nil;
    [remoteRecipientID release];
    remoteRecipientID = nil;
     ..................
    ..................

}

Советую потратить некоторое время на чтение Руководства по программированию управления памятью

Пожалуйста, смотрите мой ответ здесь: Удаление и удаление UiButtons

В нем содержится объяснение того, когда вам следует сохранять / отпускать или полагаться на авто-выпуск.Примените эти правила к вашему коду выше.Короче говоря, в любое время, когда вы выделяете что-либо, вы должны следовать за этим с помощью вызова release для этого объекта.Если этого не произойдет, у вас будет утечка памяти.

Обновление:

Вы не выпускаете созданный здесь ActivityIndicator. 

- (void)viewDidLoad {
    [super viewDidLoad];

    // ...

    activityIndicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray];
    // ...
    [self.view addSubview:activityIndicator];
}

У вас есть несколько мест, где вы звоните [[XXX alloc] init], где XXX это NSMutableArray или NSMutableString.Вы никогда не выпускаете их, и они не освобождаются автоматически, поэтому они просачиваются.

В tableView:didSelectRowAtIndexPath:, lastIndexPath не освобождается до сохранения indexPath.В viewDidLoad вы nil исключаете переменные.

И при разборе XML вы создаете и освобождаете строки, исходя из предположения, что один элемент не содержит другой.Если они вложенные, один элемент запустится раньше, чем закончится другой.В таком случае вы потеряете ссылку на исходную строку и, следовательно, утечка.Это не большая проблема, если они братья и сестры, но, судя по вашему журналу, элементы вложены.

Я слышал

[UIImage imageNamed: @ "contact.png"];

- строка памяти. Это создаст объект автоматического выпуска как возвращенный объект. Может быть, это тоже может быть проблемой.
