• (void)elcImagePickerController:(ELCImagePickerController )picker didFinishPickingMediaWithInfo:(NSArray )info { [self dismissViewControllerAnimated:YES completion:nil];

  for (UIView *v in [_scrollView subviews]) { [v removeFromSuperview]; }

  CGRect workingFrame = _scrollView.frame; workingFrame.origin.x = 0;

  NSMutableArray images = [NSMutableArray arrayWithCapacity:[info count]]; for (NSDictionary dict in info) { if ([dict objectForKey:UIImagePickerControllerMediaType] == ALAssetTypePhoto){ if ([dict objectForKey:UIImagePickerControllerOriginalImage]){ UIImage* image=[dict objectForKey:UIImagePickerControllerOriginalImage]; [images addObject:image];

          UIImageView *imageview = [[UIImageView alloc] initWithImage:image];
          [imageview setContentMode:UIViewContentModeScaleAspectFit];
          imageview.frame = workingFrame;
  
          [_scrollView addSubview:imageview];
  
          workingFrame.origin.x = workingFrame.origin.x + workingFrame.size.width;
      } else {
          NSLog(@"UIImagePickerControllerReferenceURL = %@", dict);
      }
  } else if ([dict objectForKey:UIImagePickerControllerMediaType] == ALAssetTypeVideo){
      if ([dict objectForKey:UIImagePickerControllerOriginalImage]){
          UIImage* image=[dict objectForKey:UIImagePickerControllerOriginalImage];
  
          [images addObject:image];
  
          UIImageView *imageview = [[UIImageView alloc] initWithImage:image];
          [imageview setContentMode:UIViewContentModeScaleAspectFit];
          imageview.frame = workingFrame;
  
          [_scrollView addSubview:imageview];
  
          workingFrame.origin.x = workingFrame.origin.x + workingFrame.size.width;
      } else {
          NSLog(@"UIImagePickerControllerReferenceURL = %@", dict);
      }
  } else {
      NSLog(@"Uknown asset type");
  }

  }

  self.chosenImages = images;

  [_scrollView setPagingEnabled:YES]; [_scrollView setContentSize:CGSizeMake(workingFrame.origin.x, workingFrame.size.height)]; }
