How to use QLPreviewController in the Interface Builder?

Is it possible to use the QLPreviewController in the Interface Builder? I am using storyboards and segues, and it would be lovely to also have a representation for the QLPreviewController.

I asked the same question several weeks ago. As far as I know there is no representation for the QuickLook Framework. But it shouldn't be too hard to get this done programmatically.

I suppose you have an UITableView. Then implement QLPreviewControllerDataSource into your header and the following two methods to your implementation:

- (NSInteger) numberOfPreviewItemsInPreviewController: (QLPreviewController *) controller;
- (id <QLPreviewItem>) previewController: (QLPreviewController *) controller previewItemAtIndex: (NSInteger) index;

Don't set a segue for the cells and leave the storyboard methods. Instead in the tableView:didSelectRowAtIndexPath: create a new instance of a QLPreviewController and push it onto the stack of the navigation controller.

PreviewController* previewController = [[PreviewController alloc] init];
[previewController setDataSource:self];
[previewController setDelegate:self];
[previewController setCurrentPreviewItemIndex:indexPath.row];
[self.navigationController pushViewController:previewController animated:YES];
