iOS, UIDocumentPickerViewController export, and Dropbox 38.2.2/38.3.4

[rmaddy]

My iOS app uses UIDocumentPickerViewController to export files from my app to a user's Dropbox account. This has been working just fine. It worked for me just a short time ago with an older version of the Dropbox app installed on my iPhone. I just updated to the latest Dropbox app (38.2.2 and now 38.3.4) and now when I tap on the "Save to Whatever" button at the bottom of the screen, the file is not saved at all. I've had a few users of my app report the same issue as well.

So it seems that the latest Dropbox app is no working on iOS when used to export a file to Dropbox using UIDocumentPickerViewController. Importing from Dropbox works just fine.

Thanks for the report! Can you share the relevant code snippet, as well as any error or output you might be getting in the console? Thanks in advance!

[rmaddy]

I don't have a code snippet handy. It's just a standard use of a UIDocumentPickerViewController in Export mode. But I did plug my iPhone in and captured the device console from just before selecting Dropbox from the list of document pickers up through tapping on the "Save to Personal" button in the Dropbox app UI.

There is one assertion near the end:

Assertion failure in +[DBCompanyDropboxModelExtensionWarnIfSharedRootInfo warnUploadInfoWithTargetEntry:dropboxName:](), /Users/jenkins/dev/jenkins-root/workspace/ios-app-store/xplat/dbapp-ios/Dropbox/Classes/DBCompanyDropboxModelExtensionWarnIfSharedRootInfo.m:21

I'll post more of the log in pieces, it is too long for a single post.

Just updated to version 38.3.4 of the iOS Dropbox app and the problem is still there.

[Greg-DB · Accepted solution]

Thanks! We'll look into it.

I am experiencing the same bug.  Any selection of a folder always calls the documentMenuWasCancelled method.

[Brendan D.]

I have exactly the same problem. I cannot export anymore because when you tap "Save to Personal" or whatever folder you're saving to, the 

`documentPickerWasCancelled` method is called and the upload does not happen. It works fine uploading to other cloud services. Just not Dropbox. I've tried it with iCloud Drive and OneDrive and they both upload the file and call `didPickDocumentAtURL` after the file is uploaded.

Is this a bug in my code or a bug with the latest Dropbox client? I haven't touched this code in quite a long time and it's now suddenly not working.

Thanks,

Brendan

Brendan - All evidence indicates it is an issue with the last two updates to the Dropbox app and not your application. We just need to wait for Dropbox to fix this issue with their app.
