afnetworking - startMonitoringNetworkReachability 中的 exc_bad_access
对于一个项目，我必须使用 AFNetworking。从 github 获取了新的副本，iOS 示例项目似乎正在运行。
但是 - 当我将“AFNetworking”文件夹复制到新的 Xcode 项目并尝试进行 http 调用时，它在 AFHTTPClient 的初始化程序中崩溃
所以在 [AFHTTPClient initWithBaseURL:] 中有这样的代码：
#ifdef _SYSTEMCONFIGURATION_H
[self startMonitoringNetworkReachability];
#endif
它看起来真的很愚蠢但是
1) WHEN我不链接 SystemConfiguration - 该项目无法编译
（架构 i386 的未定义符号： “_SCNetworkReachabilityCreateWithName”，引用自： -AFHTTPClient.o 中的[AFHTTPClient startMonitoringNetworkReachability]
2) 当我链接 SystemConfiguration 时 - 项目在运行时在 startMonitoringNetworkReachability 内崩溃并带有 EXC_BAD_ACCESS：
SCNetworkReachabilitySetCallback(self.networkReachability, AFReachabilityCallback, &context);
有人遇到此问题吗？从他们在 github 上称赞他们的库的方式来看，我认为它会更加精致。
For a project I have to use AFNetworking. Got fresh copy from github and the iOS example project seems to be working.
However - when I copy over the "AFNetworking" folder to a new Xcode project and try to make a http call, it crashes in the AFHTTPClient's initializer
So in [AFHTTPClient initWithBaseURL:] there's this code:
#ifdef _SYSTEMCONFIGURATION_H
[self startMonitoringNetworkReachability];
#endif
and it looks really stupid but
1) WHEN I don't link SystemConfiguration - the project doesn't compile
(Undefined symbols for architecture i386:
"_SCNetworkReachabilityCreateWithName", referenced from:
-[AFHTTPClient startMonitoringNetworkReachability] in AFHTTPClient.o)
2) WHEN I do link SystemConfiguration - the project crashes at runtime inside startMonitoringNetworkReachability with EXC_BAD_ACCESS:
SCNetworkReachabilitySetCallback(self.networkReachability, AFReachabilityCallback, &context);
Did anybody have this problem? From the way they praise their lib on github I thought it'd be more polished.

如果你的 baseURL 为零，它就会崩溃。
It will crash if your baseURL is nil.
根据文档：
您包含了框架，但是您是否在项目中的某个位置添加了
#import？As per the documentation:
You included the framework, but did you add
#import <SystemConfiguration/SystemConfiguration.h>somewhere in the project?
