AsyncSocket release模式崩溃

事情的经过是这样的，上传新项目审核， 结果被拒，提示是

2. 1 PERFORMANCE: APP COMPLETENESS
Performance - 2.1


Your app crashes on iPhone running iOS 10.0.1 connected to an IPv6 network when we tap the log-in button after filling in the demo account information.

This occurred when your app was used:
- On Wi-Fi

We have attached detailed crash logs to help troubleshoot this issue.

Next Steps

Please revise your app and test it on a device while connected to an IPv6 network (all apps must support IPv6) to ensure that it runs as expected.

意思就是：你的APP在 IPV6 网络状态、iOS10.0.1 崩溃了。

我原来是适配了ipv6的，我就定位到是因为iOS 10 的问题，然后在iOS 10 debug模式运行没问题， 重新上传还是被拒，最后在release模式终于 找到崩溃信息。

纠结了好久最后 看到也有人遇到过这种问题
解决办法：

/** 
 * This is the callback we setup for CFReadStream. 
 * This method does nothing but forward the call to it's Objective-C counterpart 
**/  
static void MyCFReadStreamCallback (CFReadStreamRef stream, CFStreamEventType type, voidvoid *pInfo)  
{  
    @autoreleasepool {  
      
        AsyncSocket *theSocket = (__bridge AsyncSocket *)pInfo;  
        [theSocket doCFReadStreamCallback:type forStream:stream];  
      
    }  
}  
  
/** 
 * This is the callback we setup for CFWriteStream. 
 * This method does nothing but forward the call to it's Objective-C counterpart 
**/  
static void MyCFWriteStreamCallback (CFWriteStreamRef stream, CFStreamEventType type, voidvoid *pInfo)  
{  
    @autoreleasepool {  
      
        AsyncSocket *theSocket = (__bridge AsyncSocket *)pInfo;  
        [theSocket doCFWriteStreamCallback:type forStream:stream];  
      
    }  
}  

修改后：

/**
 * This is the callback we setup for CFReadStream.
 * This method does nothing but forward the call to it's Objective-C counterpart
**/
static void MyCFReadStreamCallback (CFReadStreamRef stream, CFStreamEventType type, void *pInfo)
{
    @autoreleasepool {
        AsyncSocket *theSocket =[[AsyncSocket alloc]init];
        theSocket = (__bridge AsyncSocket *)pInfo;
        [theSocket doCFReadStreamCallback:type forStream:stream];
    
    }
}

/**
 * This is the callback we setup for CFWriteStream.
 * This method does nothing but forward the call to it's Objective-C counterpart
**/
static void MyCFWriteStreamCallback (CFWriteStreamRef stream, CFStreamEventType type, void *pInfo)
{
    @autoreleasepool {
        AsyncSocket *theSocket =[[AsyncSocket alloc]init];
        theSocket = (__bridge AsyncSocket *)pInfo;
        [theSocket doCFWriteStreamCallback:type forStream:stream];
    
    }
}
