iOS App审核 因IPv6遭到拒绝

问题描述：
在iTunes Connect 中苹果发来回复：
We discovered one or more bugs in your app when reviewed on iPad and iPhone running iOS 10.3.1 on Wi-Fi connected to an IPv6 network.
解决：
1.让服务器支持IPv6协议
2.或模拟IPv6环境 （谷歌或百度搜索 很多教程），测试哪里出了问题
如：我的是因为AFNetworking 被拒 
解决：2.1 更改为最新的AFNetworking :https://github.com/AFNetworking/AFNetworking
或 2.2  查看项目中 AFNetworkReachabilityManager Class 是否包含AF_INET、struct sockaddr_in 。
将：

+ (instancetype)sharedManager {
static AFNetworkReachabilityManager *_sharedManager = nil;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
struct sockaddr_in address;
bzero(&address, sizeof(address));
address.sin_len = sizeof(address);
address.sin_family = AF_INET;

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

return _sharedManager;
}

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

return _sharedManager;
}

+ (instancetype)manager
{
#if (defined(__IPHONE_OS_VERSION_MIN_REQUIRED) && __IPHONE_OS_VERSION_MIN_REQUIRED >= 90000) || (defined(__MAC_OS_X_VERSION_MIN_REQUIRED) && __MAC_OS_X_VERSION_MIN_REQUIRED >= 101100)
struct sockaddr_in6 address;
bzero(&address, sizeof(address));
address.sin6_len = sizeof(address);
address.sin6_family = AF_INET6;
#else
struct sockaddr_in address;
bzero(&address, sizeof(address));
address.sin_len = sizeof(address);
address.sin_family = AF_INET;
#endif
return [self managerForAddress:&address];
}
