我在使用SocketRocket时遇到了iOS EXC_BAD_ACCESS错误,我不知道如何进一步调试问题以确定问题是出在我身边还是在SocketRocket的一侧。如何调试iOS上的iOS EXC_BAD_ACCESS KERN_INVALID_ADDRESS iOS
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
或有时
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
我的代码库是非常简单的,基本上订阅的事件,并在队列中执行socketrocket的sendMessage(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]]];
}
我读过使用NSZombies调试问题的人,但是m y问题很少发生,因此在问题出现之前我可能会耗尽内存。它工作正常99%的时间。
有没有什么需要了解iOS可以随机崩溃使用套接字等应用程序?例如,我们启用了后台获取,这可能是一些随机崩溃的原因吗?
谢谢!
