UIDocumentInteractionController takes long time to show options

Question

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.

Answer 1

UIActivityViewController is very fast in iOS 8. However you can't open images in other 3rd party applications like Instagram, Vintiqu, and so forth.

Also, presentOpenInMenuFromRect is really faster than presentOptionsMenuFromRect in iOS 8 (iOS 8.0.2 too). But, presentOpenInMenuFromRect does not show sharing actions.

I want to provide users with "Save Image, Assign to Contact, Copy, Print, ..." on the sharing view. So, my current workaround is just as below, :(

    if( SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"8.0")) {
        [self.udic presentOpenInMenuFromRect:CGRectMake(self.view.frame.size.width/2 - 49/2, self.view.frame.size.height-49, 49, 49)  inView:self.view animated:YES];
    } else {
        [self.udic presentOptionsMenuFromRect:CGRectMake(self.view.frame.size.width/2 - 49/2, self.view.frame.size.height-49, 49, 49)  inView:self.view animated:YES];
    }

Answer 2

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.

My workaround so far is to use presentOpenInMenuFromRect instead of presentOptionsMenuFromRect, this will show less items but at least it's not causing memory issues. QuickLook option seems to be buggy under iOS 8 beta 5 as well, pdf quick look is not working either, beside movie memory issues.
