我找到了一些可以扫描本地网络并列出所有设备信息的iOS应用程序。
我不知道如何。

适用于iOS 7及更低版本
#include <ifaddrs.h>
#include <arpa/inet.h>
- (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;
}
iOS 8
[[NSHost currentHost] address]

使用可访问性,您可以获得子网IP的可访问性。
Reachability* reach = [Reachability reachabilityWithHostname:subnetIp];
Apple有一篇很棒的文章,其中涵盖了HostnameResolving主题。 https://developer.apple.com/library/ios/documentation/NetworkingInternet/Conceptual/NetworkingTopics/Articles/ResolvingDNSHostnames.html
您可以在iOS8中尝试更简单的变体
[[NSHost hostWithAddress:@"173.194.34.24"] name]
https://github.com/mongizaidi/LAN-Scan
这是一个小项目,它进行局域网扫描,你只需要解析主机名,你就会得到你想要的结果。
