Adding LSSupportsOpeningDocumentsInPlace to Info.plist makes the iCloud Drive app open too many documents in my app

Number:rdar://24886084 Date Originated:29-Feb-2016 05:19 PM
Status:Duplicate of 24745414 (Closed) Resolved:
Product:iOS Product Version:9.2.1
Classification:Other Bug Reproducible:Sometimes
 
Summary:
I added the LSSupportsOpeningDocumentsInPlace key to my Info.plist file in order to support opening documents in place.

When I now use the iCloud Drive app, many files, including Pages and Numbers documents are opened in my app when I tap them. Instead, it should display a preview of the document or open it in Pages/Numbers.

Steps to Reproduce:
- add LSSupportsOpeningDocumentsInPlace YES to the Info.plist of my app and install it on an iOS device
- launch the iCloud Drive app
- tap on a Pages document

Expected Results:
- it should display a preview of the Pages document or open the document in Pages

Actual Results:
- the Pages document opens in my app instead which cannot handle it

Regression:
I tried changing the LSHandlerRank of registered CFBundleDocumentTypes, but that didn’t change anything for me.

Notes:
My app (Textastic Code Editor) registers support for many file formats in the CFBundleDocumentTypes key including „public.text“ and things like „public.image“ in order to appear in the „Open In“ menu. Yet, I do not want it to be the default iCloud Drive handler for ALL text and image files.

I think there needs to be a way to limit the document types that the iCloud Drive app uses to open documents in an app by default.

I’ve added Textastic’s Info.plist file that contains all exported type UTIs so you can have a look at it.

I added "public.data" because not all file extensions of text files are necessarily known to the system. I do want my app to appear in the "Open In…" sheet for all files so that a user who receives a file called, say, "test.xyz" can open it in my app. However, I do not want this to result in the iCloud Drive app opening all files in my app.

Maybe the iCloud Drive app should look at the "LSHandlerRank" key or it should be possible to say "I don't want certain document types I define in my Info.plist to be opened in place" by setting another key.

For example, an app like Pages might want to have all .pages documents opened in Pages, but it does not want the iCloud Drive app let it open all the other files it technically supports.

You can also see the problem I'm describing in this Pixelmator support thread: "Why PDF files in "iCloud Drive" always open in Pixelmator" http://support.pixelmator.com/viewtopic.php?f=10&t=12401 Pixelmator can open PDF files. But users certainly do not want want all PDF files in iCloud Drive automatically open the Pixelmator app. Instead, they want to see a PDF preview inside the iCloud Drive app.

We have determined that this is an issue for you to resolve.

Your app claims to open all files:

LSItemContentTypes public.data LSHandlerRank Alternate CFBundleTypeName Unknown Document

If your app cannot actually open all files, you should not claim to handle public.data.

Please let us know whether the issue is resolved for you by updating your bug report.
