Open in + UIDocumentInteractionController : how to filter options in SDK iOS 6 (canPerformActions is deprecated)

Omer picture Omer · Sep 26, 2012 · Viewed 10.1k times · Source

Since the new SDK was release (iOS 6), the delegate method documentInteractionController:canPerformAction: of the UIDocumentInteractionControllerDelegate is deprecated.

Using that method you were able to prevent default actions like print: and copy: to appear.

The method is being called in the current version of iOS 6, but in future versions this method will not be called and my app will show actions that I don't want to support.

I read the available documentation for the UIDocumentInteractionController and its delegate and I'm not able to find a another way to do what I do in the canPerformAction method.

Any ideas?

As a plus, it would be great to be able to filter apps like mail or twitter (that appears by default) but I guess that this is not possible.

Agreed on the fact that deprecating 'canPerformAction' in the delegate is troublesome, we lost the fine grain control we used to have.

However, if all you want is to allow a document to be opened in another app, and wanted to remove Copy, Print and even Mail, I guess you are better off using OpenIn version of method to present the UIDocumentInteractionController?

i.e. for your UIDocumentInteractionController use presentOpenInMenuFromBarButtonItem:animated: or presentOpenInMenuFromRect:inView:animated:

(instead of presentOptionsMenuFromBarButtonItem:animated: or presentOptionsMenuFromRect:inView:animated:)

This way, by default, it will only show apps that can open your document, and hides Mail, Copy and Print.
