UIDocumentMenuViewController dismisses presenting view controller

Posted by: admin November 30, 2017 Leave a comment


I have a VC “A” that present VC “B” modally. B presents a UIDocumentMenuViewController
The UIDocumentMenuDelegate protocol is implemented in B.

As soon as documentMenuWasCancelled(_ documentMenu:) or documentMenu(_:, didPickDocumentPicker:) gets called the dismiss(animated:,completion:) of B gets called and i have no clue why.

Here’s my code

func presentDocumentPicker() {
    let documentTypes = [
        kUTTypeCompositeContent as String,
        kUTTypePDF as String,
    let documentMenuViewController = UIDocumentMenuViewController(
        documentTypes: documentTypes,
        in: .import
    documentMenuViewController.delegate = self
        animated: true,
        completion: nil

func documentMenu(_ documentMenu: UIDocumentMenuViewController, didPickDocumentPicker documentPicker: UIDocumentPickerViewController) {
    print("did pick")

func documentPickerWasCancelled(_ controller: UIDocumentPickerViewController) {
    print("was cancelled")

As you can see I do nothing in the implemented delegate function. And still B gets dismissed. I don’t get it.


This is caused by documentPicker(_ controller: UIDocumentPickerViewController, didPickDocumentAt url: URL) method which is called when you click on an action or when you cancel UIDocumentMenuViewController.

Hope it helps.
