鉴于以下符号化的崩溃日志，是否更有可能由于线程 5 上的 ASIHTTPRequest 或线程 3 上的 NSURLConnection 而发生崩溃？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，他们在 ASIHTTPREquest 崩溃方面有更多信息，而且它在线程 3 上，而我的 NSURLConnection 在线程 3 上，信息比其他更多。

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 还是 ASIHTTPRequest 线程，控制台输出可能会有所帮助。
但是，根据过去的经验，它似乎很有可能涉及 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，因此我建议您仔细检查在 dealloc 方法中您拥有的可以成为 ASIHTTPRequest(或 ASINetworkQueue)的委托(delegate)的每个对象:
[request cancel]
[request setDelegate:nil];
[request release];
应该为每个潜在的事件请求执行此操作。
关于ios - iPhone 崩溃、ASIHTTPRequest 或 NSURL 相关，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/5240511/
