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: http://blog.mediarain.com/2013/03/creating-ios-plugins-for-unity/ http://okita.com/Unity/2015/08/making-an-ios-plugin/ 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.
