iOS Swift 3应用程序被App Store拒绝因为AppV6网络中的应用程序崩溃

Question

我的应用程序因为应用程序在IPV6网络中崩溃而被我的应用程序商店拒绝。这是我第二次发生。我已经更新了我的代码以支持IPV6网络，并且在该代码中成功移动了两个构建版本。但是现在他们又提出了同样的问题，他们说这个问题只发生在Wi-Fi网络上。这里是我的尝试代码：

internal class Reachability 
    { 
     class func isConnectedToNetwork() -> Bool 
     { 
      var zeroAddress = sockaddr_in6() 
      zeroAddress.sin6_len = UInt8(MemoryLayout.size(ofValue: zeroAddress)) 
      zeroAddress.sin6_family = sa_family_t(AF_INET6) 

      let defaultRouteReachability = withUnsafePointer(to: &zeroAddress) { 
       $0.withMemoryRebound(to: sockaddr.self, capacity: 1) {zeroSockAddress in 
        SCNetworkReachabilityCreateWithName(kCFAllocatorDefault, "www.google.com") 
       } 
      } 

      var flags = SCNetworkReachabilityFlags() 
      if !SCNetworkReachabilityGetFlags(defaultRouteReachability!, &flags) { 
       return false 
      } 
      let isReachable = (flags.rawValue & UInt32(kSCNetworkFlagsReachable)) != 0 
      let needsConnection = (flags.rawValue & UInt32(kSCNetworkFlagsConnectionRequired)) != 0 
      return (isReachable && !needsConnection) 
     } 
    } 

帮助我找出解决这个问题的正确方案。

internal class ReachabilityCheck 
{ 
    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(MemoryLayout.size(ofValue: zeroAddress)) 
     zeroAddress.sin_family = sa_family_t(AF_INET) 

     let defaultRouteReachability = withUnsafePointer(to: &zeroAddress) 
     { 
      $0.withMemoryRebound(to: sockaddr.self, capacity: 1) {zeroSockAddress in 
       SCNetworkReachabilityCreateWithAddress(nil, zeroSockAddress) 
      } 
     } 

     var flags: SCNetworkReachabilityFlags = SCNetworkReachabilityFlags(rawValue: 0) 
     if SCNetworkReachabilityGetFlags(defaultRouteReachability!, &flags) == false 
     { 
      return false 
     } 
     // Working for Cellular and WIFI 
     let isReachable = (flags.rawValue & UInt32(kSCNetworkFlagsReachable)) != 0 
     let needsConnection = (flags.rawValue & UInt32(kSCNetworkFlagsConnectionRequired)) != 0 
     let ret = (isReachable && !needsConnection) 

     return ret 
    } 
}

你可以尝试这个请它对我工作良好与3G，4G和WiFi网络也工作。旧的不支持移动网络连接。

class func isConnectedToNetwork() -> Bool 
    { 
     var zeroAddress = sockaddr_in() 
      zeroAddress.sin_len = UInt8(sizeofValue(zeroAddress)) 
     // zeroAddress.sin_len = UInt8(MemoryLayout.size(ofValue: zeroAddress)) 
     zeroAddress.sin_family = sa_family_t(AF_INET) 

     let defaultRouteReachability = withUnsafePointer(&zeroAddress) { 
      SCNetworkReachabilityCreateWithAddress(kCFAllocatorDefault, UnsafePointer($0)) 
     } 

     var flags = SCNetworkReachabilityFlags() 
     if !SCNetworkReachabilityGetFlags(defaultRouteReachability!, &flags) { 
      return false 
     } 
     let isReachable = (flags.rawValue & UInt32(kSCNetworkFlagsReachable)) != 0 
     let needsConnection = (flags.rawValue & UInt32(kSCNetworkFlagsConnectionRequired)) != 0 
     return (isReachable && !needsConnection) 
    }
