对于我的项目,我需要获取IPhone的公共IP地址,有很多可用的示例,它们使用外部/第三方URL显示公共IP地址。我只是想知道如何在没有使用其他网址的帮助下提取IPhones的IP地址。
注意: - 我使用过这个,但只显示本地IP地址,我需要公共IP地址
func getIPAddress() -> [String] {
var addresses = [String]()
// Get list of all interfaces on the local machine:
var ifaddr : UnsafeMutablePointer<ifaddrs> = nil
if getifaddrs(&ifaddr) == 0 {
// For each interface ...
for (var ptr = ifaddr; ptr != nil; ptr = ptr.memory.ifa_next) {
let flags = Int32(ptr.memory.ifa_flags)
var addr = ptr.memory.ifa_addr.memory
// 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](count: Int(NI_MAXHOST), repeatedValue: 0)
if (getnameinfo(&addr, socklen_t(addr.sa_len), &hostname, socklen_t(hostname.count),
nil, socklen_t(0), NI_NUMERICHOST) == 0) {
if let address = String.fromCString(hostname) {
addresses.append(address)
}
}
}
}
}
freeifaddrs(ifaddr)
}
return addresses
}
我通过使用头文件在我的swift项目中使用了这个,它生成本地IP

import Darwin
var hostName = [Int8](count: 255, repeatedValue: 0)
gethostname(&hostName, hostName.count)
var hints = addrinfo()
var res = UnsafeMutablePointer<addrinfo>()
var p = UnsafeMutablePointer<addrinfo>()
var p4 = UnsafeMutablePointer<sockaddr_in>()
var p6 = UnsafeMutablePointer<sockaddr_in6>()
hints.ai_flags = AI_ALL
hints.ai_family = PF_UNSPEC
hints.ai_socktype = SOCK_STREAM
var ipstr = [CChar](count: Int(INET6_ADDRSTRLEN), repeatedValue: 0)
print("List of IP addresses on host \(String.fromCString(hostName)!)\n")
if getaddrinfo( hostName, "0", &hints, &res) == 0 {
var ipFamily = ""
var s: Int32 = 0
var port: in_port_t = 0
for(p = res; p != nil; p = p.memory.ai_next) {
switch p.memory.ai_family {
case PF_INET:
p4 = UnsafeMutablePointer<sockaddr_in>(p.memory.ai_addr)
inet_ntop(AF_INET, &p4.memory.sin_addr, &ipstr, socklen_t(INET6_ADDRSTRLEN))
ipFamily = "IPv4"
port = p4.memory.sin_port.bigEndian
case PF_INET6:
p6 = UnsafeMutablePointer<sockaddr_in6>(p.memory.ai_addr)
inet_ntop(AF_INET6, &p6.memory.sin6_addr, &ipstr, socklen_t(INET6_ADDRSTRLEN))
ipFamily = "IPv6"
port = p6.memory.sin6_port.bigEndian
default:
break
}
print("\t\(ipFamily):", String.fromCString(ipstr)!)
}
// free unmanaged memmory !!!!!
freeaddrinfo(res)
}
在我自己的电脑上打印
List of IP addresses on host Ivos-MacBook.local
IPv6: fe80::225:ff:fe40:9c72
IPv6: 2a02:130:200:1350:225:ff:fe40:9c72
IPv4: 192.168.1.106
对于外部IP,您需要外部服务的帮助(不是特定的快速: - ))

let address = try? String(contentsOf: URL(string: "https://api.ipify.org")!, encoding: .utf8)
print(address)
然后您将获得公共IP地址
