UIActivityViewController doesn't work in iOS 8

Question

I was using UIActivityViewController to share something for my application. It works well in any device prior to iOS8. The problem is the text,images are not be shown in email, twitter, Facebook in iOS 8 device or simulator.

Here is my code:

    NSString *textObject = @"Test";
    NSString *urlString = @"http://test.com";
    UIImage* image = [UIImage imageNamed:@"logo"];
    NSURL *url = [NSURL URLWithString:urlString];

    NSArray *activityItems = [NSArray arrayWithObjects:textObject, url, image, nil];

    UIActivityViewController *avc = [[UIActivityViewController alloc]
                                     initWithActivityItems:activityItems
                                     applicationActivities:nil];

    avc.excludedActivityTypes = @[UIActivityTypePostToWeibo, UIActivityTypeAssignToContact, UIActivityTypeCopyToPasteboard ];

    [self presentViewController:avc animated:YES completion:nil];

Did I do anything wrong? Thanks.

EDIT:

The new Xcode 6.1 and iOS 8.1 doesn't solve the problem. And it causes crash in email. Here are some screenshots (take email sharing as an example):

1. In iOS 7 (You can see the image)

2. In iOS 8 (Blank screen)

And the app crashes with a "MailCompositionService" exception. The part of the error message is:

Answer 1

It seems to be correct in real device but not in simulator.
