我的UITableViewController中的内存泄漏在哪里？

表视图工作正常但是当我离开视图并第二次回到它时，我得到了内存泄漏。 可能viewDidLoad中的某些内容并不确定。

我正在运行泄漏工具，并收到以下通知：

Answer 1

我看到你的大部分语句已准备好泄漏，例如在viewDidUnload方法中，你没有正确释放任何实例成员。

你需要在你分配，初始化或保留的对象上调用release。

  (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; .................. .................. } 

建议你花一些时间阅读内存管理编程指南

Answer 2

您有几个地方调用[[XXX alloc] init] ，其中XXX是NSMutableArray或NSMutableString 。 你永远不会释放它们，它们不是自动释放的，因此它们会泄漏。

Answer 3

请在此处查看我的回复： 取消分配和删除UiButtons

它包含了何时应保留/释放或依赖自动释放的说明。 将这些规则应用于上面的代码。 简而言之，任何时候你分配任何东西，你应该通过调用该对象的释放来跟随它。 如果你不这样做，你就会有内存泄漏。

更新：

您没有发布您在此处创建的activityIndi​​cator。

 - (void)viewDidLoad { [super viewDidLoad]; // ... activityIndicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray]; // ... [self.view addSubview:activityIndicator]; } 

Answer 4

在tableView:didSelectRowAtIndexPath: ， lastIndexPath在保留indexPath之前不会被释放。 在viewDidLoad ，您可以在不释放变量的情况下将变量弄清楚。

在XML解析中，您可以基于一个元素不包含另一个元素的假设来创建和释放字符串。 如果它们是嵌套的，则一个元素将在另一个元素结束之前启动。 在这种情况下，您将丢失对原始字符串的引用，从而泄漏。 如果他们是兄弟姐妹，这不是什么大问题，但是根据你记录的外观，这些元素是嵌套的。

Answer 5

我听到了

[UIImage imageNamed：@“contact.png”];

是一个记忆发生线。 它将创建一个autorelease对象作为返回的对象。 可能是这也可能是个问题。
