UIDocumentInteractionController presentOptionsMenuFromBarButtonItem error in ios8- Unknown activity items supplied - ios

Question

UIDocumentInteractionController presentOptionsMenuFromBarButtonItem gives me a console error in ios8 hardware (and not on 7.1 hardware or earlier):
Unknown activity items supplied: (
{
"com.adobe.pdf" = ;
},
""
)
In my official App Store version of my app, the app crashes at this point. When I compile and run on my iPad it just gives the error but does not crash.
My code:
In the .h:
UIDocumentInteractionController *docInteractionController;
In the .m:
self.docInteractionController = [UIDocumentInteractionController interactionControllerWithURL:fileURL];
self.docInteractionController.delegate = self;
//UIBarButtonItem *element is an element in my toolbar
[self.docInteractionController presentOptionsMenuFromBarButtonItem:element animated:YES];
If I do a NSLog of docInteractionController.UTI I see "com.adobe.pdf" at the console, so the UTI is being recognized properly.
I can get around the "Unknown activity items" by using presentOpenInMenuFromBarButtonItem instead of presentOptionsMenuFromBarButtonItem for the UIDocumentInteractionController call, but I want to show the user the print and email options as well, not only the external app opening options.
Tested on iPad version 8.0.2. Xcode version 6.0.1, deployment target 6.0 (also tested with deployment target 8.0). All objective-c. Running on iPad version 7.1 does not produce the error.

See radar: http://openradar.appspot.com/radar?id=5800473659441152
As noted you can use presentOpenInMenu instead of presentOptionsMenu. You will loose the mail option but you can do it yourself with MFMailComposeViewController with a dedicated mail button.
Or use UIActivityViewController with an "Open In" activity item.
Or just a UIActivityViewController without an "Open In" activity item if that is enough
Or do presentOptionsMenu on iOS7 runtime and UIActivityViewController on iOS8+ runtime (where share extensions exist)

For people not wanting to use UIActivityViewController because the document controller is what we want (all actions show up): you can get around the crash by retaining the UIDocumentInteractionController, e.g. by assigning it to a property and releasing when the document interaction finishes:
- (void)share:(id)sender
{
self.documentInteraction = [UIDocumentInteractionController interactionControllerWithURL:_shareURL];
_documentInteraction.delegate = self;
_documentInteraction.name = self.title;
[_documentInteraction presentOptionsMenuFromBarButtonItem:_actionItem animated:YES];
}
- (void)documentInteractionControllerDidDismissOptionsMenu:(UIDocumentInteractionController *)controller
{
if (controller == _documentInteraction) {
self.documentInteraction = nil;
}
}
The log will still show up, at least in debug, haven't checked with a release build. But it all works.

This solved the problem for me:
dispatch_async(dispatch_get_main_queue(), ^() {
[_docController presentOptionsMenuFromRect:button.bounds inView:button animated:YES];
});

Answer 4

I was getting the same console logs, but only in debug builds. Try creating a release build and you should see it still prints the "Unknown activity items supplied" error, but without the entire contents of the file.
