I have used UIDocumentInteractionController for sharing the files but it open menu options after 25 seconds in iOS 8 beta 5 and works fine in iOS 7.1.
I have verified the log which I pasted below

Im not sure what's the problem is.
I have used UIActivityViewController which didn't shown up any problem. This bug is still present in iOS 8 Release version
So I'm going with UIActivityViewController fix.
I have used TYOpenInAppActivity to show the third party apps in UIActivityViewController
NSURL *URL = [NSURL fileURLWithPath:filePath];
TTOpenInAppActivity *openInAppActivity = [[TTOpenInAppActivity alloc] initWithView:self.view andBarButtonItem:barButton];
UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:@[URL] applicationActivities:@[openInAppActivity]];
// Create pop up
self.activityPopoverController = [[UIPopoverController alloc] initWithContentViewController:activityViewController];
// Store reference to superview (UIPopoverController) to allow dismissal
openInAppActivity.superViewController = self.activityPopoverController;
// Show UIActivityViewController in popup
[self.activityPopoverController presentPopoverFromRect:((UIButton *)sender).frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
You can find the TTOpenInAppActivity controller in below link.
