Swift - 获取设备的WIFI IP地址
我需要在Swift中获取iOS设备的IP地址。这不是关于此的其他问题的重复!我需要只获得WiFi IP地址,如果没有wifi地址 - 我需要处理它。Stack Overflow上有一些关于它的问题,但是只有返回ip地址的函数。例如(来自如何在swift中获取IP地址):
func getIFAddresses() -> [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}
在这里,我得到2个值 - 来自移动互联网(我认为)的地址和我需要的WiFi地址。有没有其他方法来获得只有WiFi IP地址?
