是否可以在iOS中獲取移動數據IP地址？ （不是服務提供商的公開IP）

Question

我需要使用蜂窩網絡（而不是WiFi）獲取iPhone/iPad的IP地址。蘋果是否允許這樣做？如果否，有沒有其他方法可以獲得IP地址？

感謝您的幫助！

我使用了我的內部IP移動數據

func getIFAddresses() -> [String] { 
    var addresses = [String]() 

    // Get list of all interfaces on the local machine: 
    var ifaddr : UnsafeMutablePointer<ifaddrs>? 
    guard getifaddrs(&ifaddr) == 0 else { return [] } 
    guard let firstAddr = ifaddr else { return [] } 

    // For each interface ... 
    for ptr in sequence(first: firstAddr, next: { $0.pointee.ifa_next }) { 
     let flags = Int32(ptr.pointee.ifa_flags) 
     let addr = ptr.pointee.ifa_addr.pointee 

     // Check for running IPv4, IPv6 interfaces. Skip the loopback interface. 
     if (flags & (IFF_UP|IFF_RUNNING|IFF_LOOPBACK)) == (IFF_UP|IFF_RUNNING) { 
      if addr.sa_family == UInt8(AF_INET) || addr.sa_family == UInt8(AF_INET6) { 

       // Convert interface address to a human readable string: 
       var hostname = [CChar](repeating: 0, count: Int(NI_MAXHOST)) 
       if (getnameinfo(ptr.pointee.ifa_addr, socklen_t(addr.sa_len), &hostname, socklen_t(hostname.count), 
           nil, socklen_t(0), NI_NUMERICHOST) == 0) { 
        let address = String(cString: hostname) 
        addresses.append(address) 
       } 
      } 
     } 
    } 

    freeifaddrs(ifaddr) 
    return addresses 
}
