我喜欢在我的应用程序中显示IP地址,我已经知道如何显示WiFi IP地址但是当我在移动电话时它会显示错误,那么是否有一种方法可以在iPhone上显示移动IP地址？
这是我用于WiFi IP地址的代码:
NSString *address = @"error";
struct ifaddrs *interfaces = NULL;
struct ifaddrs *temp_addr = NULL;
int success = 0;
// retrieve the current interfaces - returns 0 on success
success = getifaddrs(&interfaces);
if (success == 0) {
// Loop through linked list of interfaces
temp_addr = interfaces;
while (temp_addr != NULL) {
if( temp_addr->ifa_addr->sa_family == AF_INET) {
// Check if interface is en0 which is the wifi connection on the iPhone
if ([[NSString stringWithUTF8String:temp_addr->ifa_name] isEqualToString:@"en0"]) {
// …如何在不使用任何使用Swift 3编程语言的第三方库的情况下获取设备IP地址.实际上我使用以下代码来获取IP地址.
func getIPAddress() -> String? {
var address : String?
var ifaddr : UnsafeMutablePointer<ifaddrs> = nil
if getifaddrs(&ifaddr) == 0 {
var ptr = ifaddr
while ptr != nil {
defer { ptr = ptr.memory.ifa_next }
let interface = ptr.memory
let addrFamily = interface.ifa_addr.memory.sa_family
if addrFamily == UInt8(AF_INET) || addrFamily == UInt8(AF_INET6) {
if let name = String.fromCString(interface.ifa_name) where name == "en0" {
var hostname = [CChar](count: Int(NI_MAXHOST), repeatedValue: 0)
getnameinfo(interface.ifa_addr, socklen_t(interface.ifa_addr.memory.sa_len),
&hostname, socklen_t(hostname.count),
nil, socklen_t(0), NI_NUMERICHOST)
address = …您建议如何在未经用户许可的情况下获取用户所在国家/地区？是否可以使用手机信号塔三角测量或 WiFi 定位来获得大概位置？您建议使用什么其他方法来猜测用户所在的国家/地区？
好的,所以我想检测用户在iOS设备中启用热点/网络共享的天气.我可以使用私人api知道它不会进入应用程序商店.
我试图通过私人api的列表/运行时标题,但有太多,无法决定哪些可能有用.
或者我是否可以知道UIApplicationWillChangeStatusBarFrameNotification在私有api中被触发的位置(可能需要调用活动调用和激活的热点等)
我试过检测个人热点并使用CaptiveNetwork,但它只返回连接的wi-fi ssid而不是创建的热点.
任何分享的知识都会非常有帮助
更新:@creker
使用上面的代码,编译器显示错误"SCDynamicStoreCreate不可用:在iOS上不可用.所以我进入SCDynamicStore.h并更改了以下内容
SCDynamicStoreRef
SCDynamicStoreCreate (
CFAllocatorRef allocator,
CFStringRef name,
SCDynamicStoreCallBack callout,
SCDynamicStoreContext *context
) __OSX_AVAILABLE_STARTING(__MAC_10_1,__IPHONE_NA);
至
SCDynamicStoreRef
SCDynamicStoreCreate (
CFAllocatorRef allocator,
CFStringRef name,
SCDynamicStoreCallBack callout,
SCDynamicStoreContext *context
) __OSX_AVAILABLE_STARTING(__MAC_10_1,__IPHONE_6_0);
现在我能够获得状态1022和1023的字典.只是想通过更改这样的文件来确认(以前没做过)我将在归档构建(或任何其他问题)中存在任何问题,除此之外我们的事实知道这段代码不会进入应用程序商店

let addrFamily = interface?.ifa_addr.pointee.sa_family

// wifi = ["en0"]
