内存泄漏。我如何着手修复它们呢？

Question

我得到了几个内存泄漏。所有这些在代码-ASIHTTPRequest中都有最后的位置。早些时候，我认为是ASIhtt库在泄漏内存。然而，它看起来可能只是指向创建对象的位置，而泄漏的原因实际上是代码中的。下面是一个内存泄漏堆栈的示例。我需要知道我应该如何去解决这些问题。我的方法应该是什么。谢谢

Answer 1

1. 启用ARC
2. 停止使用ASIHTTPRequest。开发人员在网站顶部发布：

请注意，我已经不在这个库上工作了--您可能想要考虑在新项目中使用其他库。

我是认真的!这个库的最后一次更新是在两年多以前！

使用AFNetworking的

Answer 2

我建议使用Instruments中的Leaks工具。Here is a tutorial帮助您入门。

Answer 3

按Xcode分析->产品->分析它将按蓝色指示器显示所有内存泄漏的位置。看到这一点，并尝试删除这些非潜在的泄漏。
