title: Ios creating simple camera overlay in Xcode how?
body: <p>As the title says, I need to create a very simple camera overlay while taking photos with <code>UIImagePickerController</code>. I want to add very simple <code>.png</code> file (like an empty box) over the camera but I can't figure out how to do it.</p>
  
  <p>I've checked most of the tutorials in this webpage but don't understand most of them. It seems very hard to me and adding one simple <code>.png</code> file to the camera overlay should be easier than that.</p>
  
  <pre><code>(IBAction) getPhoto:(id) sender {
      UIImagePickerController * picker = [[UIImagePickerController alloc] init];
      picker.delegate = self;
  
      if((UIButton *) sender == choosePhotoBtn) {
          picker.sourceType = UIImagePickerControllerSourceTypeCamera;
      } else {
  
      }
  
      label1.text =@"PHOTO ACTION";
  
      [self presentModalViewController:picker animated:YES];
  }
  
  - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
      [picker dismissModalViewControllerAnimated:YES];
      imageView.image = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
  }
  </code></pre>
  
  <p>Where should I implement my overlay code? What classes should I use and how can I do it?</p>
