关于获取iPhone的WiFi地址、UUID、IP相关方法

经常我们会遇到获取iPhone的WiFi地址、UUID、IP的相关信息，下面就总结下给大家分享下

• .h文件

     #import <Foundation/Foundation.h>
    
    @interface WifiName : NSObject
    
    @property(nonatomic,strong,readonly) NSString * wifiName;
    
    @property(nonatomic,strong,readonly)NSString * UUID;
    
    @property(nonatomic,strong,readonly)NSString * IP;
    
    @end

• .m 文件

    #import "WifiName.h"
    #import <SystemConfiguration/CaptiveNetwork.h> // wifi库
    #import <ifaddrs.h>   // IP库
    #import <arpa/inet.h>
    @implementation WifiName
    
    -(NSString * )wifiName{
        NSString *wifi = @"Not Found";
        CFArrayRef myArray = CNCopySupportedInterfaces();
        if (myArray != nil) {
            CFDictionaryRef myDict = CNCopyCurrentNetworkInfo(CFArrayGetValueAtIndex(myArray, 0));
            if (myDict != nil) {
                NSDictionary *dict = (NSDictionary*)CFBridgingRelease(myDict);
                wifi = [dict valueForKey:@"SSID"];
            }
        }
        return wifi;
    }
    
    -(NSString*)UUID{
        CFUUIDRef puuid = CFUUIDCreate( nil );
        CFStringRef uuidString = CFUUIDCreateString( nil, puuid );
        NSString * result = (NSString *)CFBridgingRelease(CFStringCreateCopy( NULL, uuidString));
        CFRelease(puuid);
        CFRelease(uuidString);
        return result;
    }
    
    -(NSString*)IP{
        NSString *address = @"Not Found";
        struct ifaddrs *interfaces = NULL;
        struct ifaddrs *temp_addr = NULL;
        int success = 0;
        success = getifaddrs(&interfaces);
        if (success == 0) {
            temp_addr = interfaces;
            while(temp_addr != NULL) {
                if(temp_addr->ifa_addr->sa_family == AF_INET) {
                    if([[NSString stringWithUTF8String:temp_addr->ifa_name] isEqualToString:@"en0"]) {
                        address = [NSString stringWithUTF8String:inet_ntoa(((struct sockaddr_in *)temp_addr->ifa_addr)->sin_addr)];
                    }
                }
                temp_addr = temp_addr->ifa_next;
            }
        }
        freeifaddrs(interfaces);
        return address;
    }
    
    @end
