// 修改之前

    static AFNetworkReachabilityManager *_sharedManager = nil;
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        _sharedManager = [self manager];
    });

    return _sharedManager;
}
// 修改之后
+ (instancetype)sharedManager {

        bzero(&address, sizeof(address));
        address.sin6_len = sizeof(address);

        _sharedManager = [self managerForAddress:&address];
    });
    
    return _sharedManager;
}
