我是swift和xcode的新手,因为IPV6我的应用被拒绝了:
表现 - 2.1
当我们执行以下操作时,您的应用程序在iPad和运行iOS 9.3.5的iPhone上崩溃连接到IPv6网络:
具体来说,当我们触摸应用程序右下角的"更多"按钮时,它会崩溃.
我花了很多时间在ipv6上阅读并得出结论,它可能是我正在使用的可达性类.
我有几个问题,如何修改代码以包含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
}
}
因为我正在使用http请求,我的服务器也必须配置为ipv6吗？
任何帮助将非常感激!

如拒绝通知中所示,您的问题源于对仅IPv6和其他现代网络拓扑不再有效的假设.这里有两个步骤......
可识别API(请参阅SCNetworkReachability参考)用于在识别连接问题后进行诊断.许多应用程序错误地使用这些API通过调用
SCNetworkReachabilityCreateWithAddress方法并向其传递IPv4地址来主动检查Internet连接0.0.0.0,这表明网络上有路由器.但是,路由器的存在并不能保证存在Internet连接.通常,避免预检网络可达性.只是尝试建立连接并优雅地处理故障.如果必须检查网络可用性,请避免调用该SCNetworkReachabilityCreateWithAddress方法.调用SCNetworkReachabilityCreateWithName方法并将其传递给主机名.某些应用程序还通过该
SCNetworkReachabilityCreateWithAddress方法传递IPv4地址(169.254.0.0自我分配的链接本地地址),以检查活动的Wi-Fi连接.要检查Wi-Fi或蜂窝连接,请查找网络可达性标志kSCNetworkReachabilityFlagsIsWWAN.
在上述链接和WWDC16会话714"现代互联网网络"中,有更好的建议支持IPv6和现代网络.
