您有多个地方可以致电[[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。

请在此处查看我的回复：Deallocating and removing 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，只要您分配任何内容，您就应该通过调用该对象上的 release 来关注它。如果不这样做，就会发生内存泄漏。

您没有发布您在此处创建的activityIndicator。
- (void)viewDidLoad {
[super viewDidLoad];
// ...
activityIndicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray];
// ...
[self.view addSubview:activityIndicator];
}

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;

在tableView:didSelectRowAtIndexPath:中，lastIndexPath在保留indexPath之前未发布。在viewDidLoad中，您nil输出变量而不释放它们。
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，元素是嵌套的。

我听到了
[UIImage imageNamed：@“contact.png”];
是内存发生线。它将创建一个autorelease对象作为返回的对象。也许这也可能是一个问题。
