ios - iPhone 崩溃，ASIHTTPRequest 或 NSURL 相关

Question

给定以下符号化的崩溃日志，是否更可能是由于线程 5 上的 ASIHTTPRequest 或线程 3 上的 NSURLConnection 而导致崩溃？我问是因为这个问题有类似的问题:ASIHTTPRequest, EXC_BAD_ACCESS when request did finished

但是，他们有更多关于他们的 ASIHTTPREquest 崩溃的信息，它在线程 3 上，而我的 NSURLConnection 在线程 3 上，比另一个有更多信息。

Answer 1

正如其他人所说，故障转储中没有足够的信息来判断可能涉及的是 NSURLConnection 线程还是 ASIHTTPRequest 线程，控制台输出可能会有所帮助。

不过，根据以往的经验，似乎很有可能涉及到ASIHTTPRequest。

您使用的是什么版本的 ASIHTTPRequest？

人们对 ASIHTTPRequest 最常见的问题是请求与委托(delegate)生命周期的问题，所以我建议仔细检查你拥有的每个对象，它可以是 ASIHTTPRequest(或 ASINetworkQueue)的委托(delegate)，在 dealloc 方法中:

[request cancel]
[request setDelegate:nil];
[request release];

应该对每个 潜在的事件请求执行此操作。
