Unable to add QLPreviewController as childViewController iOS10

I am trying to add QLPreviewController as childViewController. However I got no success on iOS10. I have checked this link.. No success. Here is my code:

let previewController:QLPreviewController = QLPreviewController()

previewController.dataSource = self
previewController.currentPreviewItemIndex = 0

self.addChildViewController(previewController)
self.view.addSubview(previewController.view)
previewController.view.didMoveToSuperview()

This code block works on the iOS9. Any help will be appreciated.

Solution

  • In this case, the view you are has a zero rect. That is why it is not visible. You can solve it in two different ways: - Using auto layout. - Setting to frame and the autoresizing mask:

    previewController.view.frame = self.view.frame;
self.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
