Ios 在iphone6上崩溃。找不到原因

我正在开发一个跟踪用户的应用程序。我的应用程序正在崩溃，在崩溃循环发生后，我将应用程序放在后台。每次我启动应用程序都会崩溃。我已经标记了崩溃日志，但无法找到崩溃的确切原因。下面给出了符号化的崩溃日志。谁能告诉我原因吗

EXC\u BAD\u ACCESS通常表示您正在向无效内存地址发送一条Obj-C消息。通常发生这种情况是因为您正在使用的对象已被解除分配，而您并不期望它会被解除分配（这里可能是HTTPMessage）

您可以使用NSZombieEnabled获取更多信息

简化it的步骤：

产品->方案->编辑方案（cmd+选中启用僵尸）

符号化崩溃日志看起来不一样。对于符号化，我正在使用以下命令/Applications/Xcode.app/Contents/SharedFrameworks/DTDeviceKitBase.framework/Versions/A/Resources/symbolicatecrash-v myapp.crash 2>symbolicate.logsame在6s上，仍然无法理解原因。我正在了解这一点s仅在iPhone 6上崩溃。在其他设备上，我没有得到此崩溃。此崩溃是随机的。不会每次都复制。不确定，但如果您的网络太慢，并且在您的响应到来之前，您可能会被重定向。因此您的响应处理程序将无法通过代理获得。。。
