AsyncSocket第三方开源库经常会在release环境下出现接收消息闪退

自从Xcode7出来以后，项目中使用的AsyncSocket第三方开源库经常会在release环境下出现接收消息闪退等现象，但是在debug环境下面则没有相关的问题，导致很难找到问题所在以及解决方法。在花费了很长时间查找资料以及相关问题搜索以后，发现有可能是因为在Xcode7在打包的时候，Xcode会自动精简代码块，导致问题某些代码在release环境下出现内存管理不到位而抛野指针，出现闪退现象。

在经过大量修改和测试以后，发现修改AsyncSocket开源库中的AsyncSocket.m的以下代码，闪退问题不在出现，修改前：

/**
* 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 = (__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 = (__bridge AsyncSocket *)pInfo;
[theSocket doCFWriteStreamCallback:type forStream:stream];

}
}

修改后的代码如下：

static void MyCFReadStreamCallback (CFReadStreamRef stream, CFStreamEventType type, void *pInfo)
{
@autoreleasepool {

AsyncSocket *theSocket =[[AsyncSocket alloc]init];
theSocket =  (__bridge AsyncSocket *)pInfo;
[theSocket doCFReadStreamCallback:type forStream:stream];

}
}

static void MyCFWriteStreamCallback (CFWriteStreamRef stream, CFStreamEventType type, void *pInfo)
{
@autoreleasepool {
AsyncSocket *theSocket =[[AsyncSocket alloc]init];
theSocket = (__bridge AsyncSocket *)pInfo;
[theSocket doCFWriteStreamCallback:type forStream:stream];

}
}

修改的核心是:为接收消息时的对象重新开辟一下内存，让其不会被提前释放而抛出野指针。

以上只是我个人的理解，有说错的或者不对的地方，希望大家能理解。
