How to use didUpdateToLocation to Xcode Touch Library project .m to .mm file C syntex

How to use didUpdateToLocation to Xcode Touch Library project so i can write the plugin for GPS using in Unity3d.

first i write a native app in objective c for getting the gps location on my iphone it works fine as native xcode object c projects does. now my next goal is to make a library or cocos touch static library refereces as link listed below:

The Orignal Code is so easy and implementation is also easy

but for cocos touch static library .mm file there are some differences :

Orignal Implementation :

 (void)viewDidLoad {
     [super viewDidLoad];
     self.locationManager = [[CLLocationManager alloc]init];
      self.locationManager.desiredAccuracy = kCLLocationAccuracyBest;
     self.locationManager.delegate = self;
 }

And my didToUpdateLocation

 - (void)locationManager:(CLLocationManager *)manager
     didUpdateToLocation:(CLLocation *)newLocation
            fromLocation:(CLLocation *)oldLocation
 {
   self.lblLong.text = [NSString stringWithFormat:@"%f",manager.location.coordinate.latitude];
     self.lblLat.text = [NSString stringWithFormat:@"%f",manager.location.coordinate.longitude];
 
 }

This method is update automatically when recieved new location you have to write it in .m file.

Now i create a Cocos Static Touch Library Prject and make a .mm file which is basically in C not objective c So how to call these method i try to copy and paste it but it does not work

 [self.locationManager startUpdatingLocation];

This is for starting location services.
