IPV6快速可达性 [英] IPV6 Swift Reachability
问题描述
我是Swift和Xcode&的新手.由于IPV6而拒绝了我的应用程序:
I am new to swift and xcode & have had my app rejected due to IPV6:
性能-2.1
Performance - 2.1
在以下情况下，您的应用程序在连接到IPv6网络的iPad和运行iOS 9.3.5的iPhone上崩溃:
Your app crashes on an iPad and an iPhone running iOS 9.3.5 connected >to an IPv6 network when we:
具体地说，当我们触摸应用程序右下角的更多"按钮时，它崩溃了.
Specifically, when we touch the More button in the bottom right hand corner of the app it crashed.
我花了很多时间阅读有关ipv6的内容，并得出结论，这可能是我正在使用的可达性课程.
I have spent a lot of the day doing reading around ipv6 and have concluded that it may be the reachability class I am using.
我有几个问题，如何修改代码以包含ipv6:
I have a couple of questions, how would I modify the code to include ipv6:
public class Reachability {
class func isConnectedToNetwork() -> Bool {
var zeroAddress = sockaddr_in(sin_len: 0, sin_family: 0, sin_port: 0, sin_addr: in_addr(s_addr: 0), sin_zero: (0, 0, 0, 0, 0, 0, 0, 0))
zeroAddress.sin_len = UInt8(sizeofValue(zeroAddress))
zeroAddress.sin_family = sa_family_t(AF_INET)
let defaultRouteReachability = withUnsafePointer(&zeroAddress) {
SCNetworkReachabilityCreateWithAddress(kCFAllocatorDefault, UnsafePointer($0))
}
var flags: SCNetworkReachabilityFlags = SCNetworkReachabilityFlags(rawValue: 0)
if SCNetworkReachabilityGetFlags(defaultRouteReachability!, &flags) == false {
return false
}
let isReachable = (flags.rawValue & UInt32(kSCNetworkFlagsReachable)) != 0
let needsConnection = (flags.rawValue & UInt32(kSCNetworkFlagsConnectionRequired)) != 0
return isReachable && !needsConnection
}
}
由于我使用的是http请求，我的服务器也必须配置为ipv6吗?
and because I am using http requests does my server have to be configured for ipv6 as well?
任何帮助将不胜感激！

推荐答案
从拒绝通知中可以看出，您的问题来自于仅在IPv6和其他现代网络拓扑上不再有效的假设.这里有两个步骤可以继续前进...
As seen in the rejection notice, your problems stem from assumptions that are no longer valid on IPv6-only and other modern network topologies. There's two steps to move forward here...
- Don't use reachability to "preflight" before making connections. From Apple's guide to supporting modern networks:
可达性API(请参阅 SCNetworkReachability参考)用于诊断目的之后确定连接问题.许多应用程序错误地使用这些API来调用
SCNetworkReachabilityCreateWithAddress方法，并将其传递给0.0.0.0的IPv4地址，该地址表示网络上存在路由器.但是，路由器的存在并不能保证存在互联网连接.通常，避免预检网络可达性.只需尝试建立连接并妥善处理故障即可.如果必须检查网络可用性，请避免调用SCNetworkReachabilityCreateWithAddress方法.调用SCNetworkReachabilityCreateWithName方法，并将其传递为主机名.
The Reachability APIs (see SCNetworkReachability Reference) are intended for diagnostic purposes after identifying a connectivity issue. Many apps incorrectly use these APIs to proactively check for an Internet connection by calling the
SCNetworkReachabilityCreateWithAddressmethod and passing it an IPv4 address of0.0.0.0, which indicates that there is a router on the network. However, the presence of a router doesn’t guarantee that an Internet connection exists. In general, avoid preflighting network reachability. Just try to make a connection and gracefully handle failures. If you must check for network availability, avoid calling theSCNetworkReachabilityCreateWithAddressmethod. Call theSCNetworkReachabilityCreateWithNamemethod and pass it a hostname instead.
某些应用还通过 SCNetworkReachabilityCreateWithAddress 方法将IPv4地址设置为169.254.0.0，这是一个自行分配的本地链接地址，用于检查有效的Wi-Fi连接.要检查Wi-Fi或蜂窝连接性，请查找网络可达性标志 kSCNetworkReachabilityFlagsIsWWAN 代替.
Some apps also pass the SCNetworkReachabilityCreateWithAddress method an IPv4 address of 169.254.0.0, a self-assigned link-local address, to check for an active Wi-Fi connection. To check for Wi-Fi or cellular connectivity, look for the network reachability flag kSCNetworkReachabilityFlagsIsWWAN instead.
- Test with IPv6-only networks before submitting to the App store. You can set up a NAT64 gateway on your development Mac to create an IPv6-only network for use by your test devices.
