Here is a piece of code I write in:- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { PHAuthorizationStatus status = [PHPhotoLibrary authorizationStatus]; if (status == PHAuthorizationStatusAuthorized) { if (@available(iOS 11.0, *)) { NSDictionary *mediaMetadata= info[UIImagePickerControllerMediaMetadata];.................mediaMetadata does not contain any GPS coordinates information (in two cases:picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;and: picker.sourceType = UIImagePickerControllerSourceTypeCamera; )If I use a photo from Photos, for example: NSString *imgPath = [[NSBundle mainBundle] pathForResource:@"IMG_1998" ofType:@"jpeg"]; NSURL *myURL = [NSURL fileURLWithPath:imgPath]; CGImageSourceRef imgSourceRef = CGImageSourceCreateWithURL((CFURLRef)myURL, NULL); NSDictionary *mediaMetadata = (NSDictionary *) CFBridgingRelease(CGImageSourceCopyPropertiesAtIndex(imgSourceRef,0,NULL));.......Then, mediaMetadata contains a lot of information, however, GPS data still does not appear.Please show me how to get the GPS data?. Sincerely thank.
