如何在iPhone sdk中以编程方式获取设备名称？

i get the device Mac and IP Address. But, don't get the device name.

我得到设备Mac和IP地址。但是,不要获取设备名称。

any idea how to get more info if possible like "Network Utility" of device ?

任何想法如何获得更多的信息,如可能像设备的“网络实用程序”?

On iOS 4.1+, you can do this: If you are looking for SSID Name..

在iOS 4.1+上,您可以这样做:如果您正在寻找SSID名称..

import

- (id)fetchSSIDInfo
{
    NSArray *ifs = (id)CNCopySupportedInterfaces();
    NSLog(@"%s: Supported interfaces: %@", __func__, ifs);
    id info = nil;
    for (NSString *ifnam in ifs) {
        info = (id)CNCopyCurrentNetworkInfo((CFStringRef)ifnam);
        NSLog(@"%s: %@ => %@", __func__, ifnam, info);
        if (info && [info count]) {
            break;
        }
        [info release];
    }
    [ifs release];
    return [info autorelease];
}

NSLog(@"uniqueIdentifier: %@", [[UIDevice currentDevice] uniqueIdentifier]);
NSLog(@"name: %@", [[UIDevice currentDevice] name]);
NSLog(@"systemName: %@", [[UIDevice currentDevice] systemName]);
NSLog(@"systemVersion: %@", [[UIDevice currentDevice] systemVersion]);
NSLog(@"model: %@", [[UIDevice currentDevice] model]);
NSLog(@"localizedModel: %@", [[UIDevice currentDevice] localizedModel]);

#import <ifaddrs.h>
#import <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;
