如何通过Native.js 的ios接口实现在IOS里面获取wifi模块的MAC地址？？

需要写插件实现目前NJS暂不支持改功能

#import <ifaddrs.h>  
#import <arpa/inet.h>  
#import "PGMethod.h"  
#import "PGPlugin.h"  
//1.插件实现  
@interface  IF: PGPlugin  
- (void)getAddresses:(PGMethod*)method;  
@end  

@implementation IF  

- (void)getAddresses:(PGMethod*)method {  
    NSString *callbackID = [method getArgumentAtIndex:0];  
    struct ifaddrs *interfaces = NULL;  
    struct ifaddrs *enumAddr = NULL;  
    NSMutableDictionary *ret = [NSMutableDictionary dictionary];  
    if ( 0 == getifaddrs(&interfaces)) {  
        enumAddr = interfaces;  
        while(enumAddr != NULL) {  
            if(enumAddr->ifa_addr->sa_family == AF_INET) {  
                NSString *address = [NSString stringWithUTF8String:inet_ntoa(((struct sockaddr_in *)enumAddr->ifa_addr)->sin_addr)];  
                NSString *ifName = [NSString stringWithUTF8String:enumAddr->ifa_name];  
                //NSLog(@"sa_family--%d---Name:[%@]---Addr:[%@]", temp_addr->ifa_addr->sa_family, ifName, address);  
                [ret setObject:address forKey:ifName];  
            }  
            enumAddr = enumAddr->ifa_next;  
        }  
        freeifaddrs(interfaces);  
    }  
    [self toSucessCallback:callbackID withJSON:ret];  
}  

@end  

//2.注册插件  
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions  
{  
    BOOL ret = [PDRCore initEngineWihtOptions:launchOptions  
                                  withRunMode:PDRCoreRunModeNormal];  

    [[PDRCore Instance] regPluginWithName:@"IF" impClassName:@"IF" type:PDRExendPluginTypeFrame javaScript:@";(function(plus){\  
     var B = window.plus.bridge,\  
           _PLUSNAME = 'IF';\  
     plus.IF = {\  
       getAddresses:function(SuccessCallback)\  
         {\  
           var callbackid = B.callbackId(SuccessCallback);\  
           B.exec(_PLUSNAME,'getAddresses',[callbackid]);\  
         }\  
       };\  
     })(window.plus);"];  
//3.manifest.json permissions节点下添加  
"permissions": {  
        "IF": {  
            "description": ""  
        },  
//4. Example  
plus.IF.getAddresses(   
    function( addrs ) {  
        console.log(JSON.stringify(addrs))  
    }  
);
