如何在iOS上调试iOS EXC_BAD_ACCESS KERN_INVALID_ADDRESS

我在使用SocketRocket时遇到iOS EXC_BAD_ACCESS错误,我想知道我可以做些什么来进一步调试问题,以确定问题是在我身边,还是在SocketRocket方面.

我得到的堆栈跟踪是:

Crashed: com.apple.main-thread
EXC_BAD_ACCESS KERN_INVALID_ADDRESS at 0x2000000c
raw
0    libobjc.A.dylib     objc_msgSend + 5
1    OMlearnings         SRWebSocket.m line 692    __30-[SRWebSocket _failWithError:]_block_invoke_2
2    libdispatch.dylib   _dispatch_call_block_and_release + 10
10   UIKit               UIApplicationMain + 1136
11   OMlearnings         main.m line 16    main

或者有时候

Crashed: NSOperationQueue Serial Queue
EXC_BAD_ACCESS KERN_INVALID_ADDRESS at 0xc
raw
0    libobjc.A.dylib     objc_msgSend + 5
1    OMlearnings         SRWebSocket.m line 613    -[SRWebSocket scheduleInRunLoop:forMode:]
2    OMlearnings         SRWebSocket.m line 600    -[SRWebSocket _connect]
3    OMlearnings         OMSRealTimeTeamDashboard.m line 157    -[OMSRealTimeTeamDashboard sendMessage:]
4    OMlearnings         OMSRealTimeTeamDashboard.m line 171    -[OMSRealTimeTeamDashboard eventReceived:]
5    CoreFoundation      __invoking___ + 68
6    CoreFoundation      -[NSInvocation invoke] + 282
7    Foundation          -[NSInvocationOperation main] + 112
8    Foundation          -[__NSOperationInternal _start:] + 770
14   libsystem_pthread.dylib _pthread_wqthread + 298

我的代码库非常简单,基本上订阅事件,并在队列中执行socketrocket sendMessage(以处理并发)

[signalServices subscribe:my-event toBlock:^(NSNotification * notification) {
    [this.queue addOperation:[[NSInvocationOperation alloc] initWithTarget:self selector:@selector(eventReceived:) object:notification]];
}];

- (void)eventReceived: (NSNotification *)notification {
    // ...
    [socket send:[NSString stringWithFormat:@"%i,1,%@", currentUserId.intValue, [NSNumber numberWithInt: rate.value]]];
}

我已经阅读过使用NSZombies调试问题的人,但我的问题很少发生,所以在问题变得可见之前我可能会耗尽内存.它在99%的时间内都能正常工作.

有没有什么可以知道的iOS可以随机崩溃使用套接字的应用程序等？例如,我们启用了后台提取,这可能是一些随机崩溃的原因吗？

谢谢 !
