如何在iOS / macOS上以编程方式获取我的IP地址?我想以编程方式获取iPad的IP地址。如何查询网络子系统以找出我的IPv4(和IPv6)地址是什么?PS:我可以以某种方式禁用IPv6吗?

在您的实现文件.m中,
#import <ifaddrs.h>#import <arpa/inet.h>// Get IP Address- (NSString *)getIPAddress {
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"]) {
// Get NSString from C String
address = [NSString stringWithUTF8String:inet_ntoa(((struct sockaddr_in *)temp_addr->ifa_addr)->sin_addr)];
}
}
temp_addr = temp_addr->ifa_next;
}
}
// Free memory
freeifaddrs(interfaces);
return address;}- 3 回答
