objective c - Facebook, Twitter icon not showing in UIActivityViewController on iOS7

Question

I have added this code for presenting a UIActivityViewController:

-(IBAction)activityAction:(id)sender
{
    UIActivityViewController *activityViewController = [[UIActivityViewController alloc]initWithActivityItems:[NSArray arrayWithObjects:@"Hello Welcome!",[UIImage imageNamed:@"scene3.jpg"],nil] applicationActivities:nil];

     activityViewController.excludedActivityTypes = @[UIActivityTypePostToFacebook, UIActivityTypePostToTwitter, UIActivityTypePostToWeibo, UIActivityTypeAssignToContact];
    [self presentViewController:activityViewController animated:YES completion:nil];
}

Facebook, Twitter and Weibo icons are not showing in iOS7. In iOS6, all the icons are showing correctly. See the screenshot below:

How can I solve this?

Answer 1

You're probably not logged in to Facebook or Twitter in the devices Settings. They won't show up here unless the user is logged in. File a bug with Apple.
