title: Cant make explicit method call from didFinishPickingMediaWithInfo
body: <p>I have a tabBar app with four tabs. Every tab has a camera button on the left side of each tab view's <code>UINavigationBar</code>. After clicking the camera button, entering camera mode, taking a pic, and finally selecting "Use photo", the picture should be transferred to a different ViewController and placed in a <code>UIImageView</code> that is only revealed after a method named <code>attachButtonInvoked</code> is triggered. Here is my methodology, please ignore commented lines:</p>
  
  <pre><code>- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
  {
      //UIImage * image = [info objectForKey:UIImagePickerControllerEditedImage];
      //[picker dismissViewControllerAnimated:NO completion:nil];
  
  
      UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];
      //UIImageWriteToSavedPhotosAlbum(image,nil,nil,nil);
  
      RGPostTableViewController *postTableView = [self.storyboard instantiateViewControllerWithIdentifier:@"postTableView"];
      RGPostViewController *postView = [self.storyboard instantiateViewControllerWithIdentifier:@"postView"];
      UINavigationController *postControl = [self.storyboard instantiateViewControllerWithIdentifier:@"postControl"];
  
  
  
      //postView.postImageView.image = image;
  
      //[picker dismissViewControllerAnimated:NO completion:nil];
  
      [picker presentViewController:postControl animated:YES completion:nil];
  
      NSLog(@"%@", image);
  
      [postTableView attachButtonInvoked];
      postView.postImageView.image = image;
  
  }
  </code></pre>
  
  <p>So far I am getting the image. But I cannot successfully call <code>attachButtonInvoked</code>; it is not revealing the UIImageView and setting the picture.</p>
