EXC_BAD_ACCESS 通常意味着您正在向无效的内存地址发送 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释放，而您却没有预料到它会被释放（此处可能是 HTTPMessage）。

**Thread 6 Crashed:
0   libobjc.A.dylib                 0x32da1c98 objc_msgSend + 16
1   CoreFoundation                  0x328c519a CFRelease + 62
2   CFNetwork                       0x3563c378 HTTPMessage::~HTTPMessage() + 56

它在另一部手机上工作的原因可能只是自动释放的对象没有同时释放。您应该检查您的保留/释放余额，并可以使用 NSZombieEnabled 来获取更多信息。

EXC_BAD_ACCESS generally means that you are sending a obj c message to an invalid memory address. Usually this happens because an object that you are using has been deallocated, while you weren't expecting it to be (here, probably HTTPMessage).

**Thread 6 Crashed:
0   libobjc.A.dylib                 0x32da1c98 objc_msgSend + 16
1   CoreFoundation                  0x328c519a CFRelease + 62
2   CFNetwork                       0x3563c378 HTTPMessage::~HTTPMessage() + 56

The reason it works on another phone is probably just that autoreleased objects aren't being released at the same time. You should check your retain/release balances and can use NSZombieEnabled to get more information.
