ios - IOS 8.4 UIActivityViewController Viber crush

Question

I use UIActivityViewController for posting text and image to socials. When I tap Viber, it give me console messages:

1)plugin com.viber.app-share-extension interrupted

2)Hub connection error Error Domain=NSCocoaErrorDomain Code=4097 "The operation couldn’t be completed. (Cocoa error 4097.)" (connection to service named com.viber.app-share-extension) UserInfo=0x14f51ef0

Code:

NSArray *shareItems = @[ image, message];

UIActivityViewController *activityController = [[UIActivityViewController alloc] initWithActivityItems:sharingArray
                                                                            applicationActivities:nil;
[self presentViewController:ac animated:YES completion:nil];'

How to fix it? Or how to catch exception from UIActivityViewController?
