UIActivityViewController Background Color - iphone

Question

So I have a UIActivityViewController in my Application. How do I change the background color.
And I also have a quick how to add Facebook and twitter to my UIActivityViewController.
The Code:
- (IBAction)Social:(id)sender {
UIActivityViewController *social = [[UIActivityViewController alloc]initWithActivityItems:[NSArray arrayWithObjects:#"Travel+ Rocks",nil] applicationActivities:nil];
social.excludedActivityTypes = #[UIActivityTypeCopyToPasteboard,UIActivityTypeAssignToContact,UIActivityTypePostToWeibo,UIActivityTypePrint];
[self presentViewController:social animated:YES completion:nil];
[social setCompletionHandler:^(NSString *activityType, BOOL completed)
{
NSLog(#"Activity = %#",activityType);
NSLog(#"Completed Status = %d",completed);
if (completed)
{
// UIAlertView *objalert = [[UIAlertView alloc]initWithTitle:#"Alert" message:#"Your Posts were sucessful" delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
// [objalert show];
// objalert = nil;
}else
{
// UIAlertView *objalert = [[UIAlertView alloc]initWithTitle:#"Alert" message:#"Your Posts weren't sucessful" delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
// [objalert show];
// objalert = nil;
}
}];
}
These Piece of Code fix the Background Eror:
NSString *message = [NSString stringWithFormat:#""];
NSString *textToShare = message;
UIImage *imageToShare = [UIImage imageNamed:#""];
NSArray *activityItems = [[NSArray alloc] initWithObjects:textToShare, imageToShare,nil];
UIActivity *activity = [[UIActivity alloc] init];
NSArray *applicationActivities = [[NSArray alloc] initWithObjects:activity, nil];
UIActivityViewController *activityVC =
[[UIActivityViewController alloc] initWithActivityItems:activityItems
applicationActivities:applicationActivities];
[self presentViewController:activityVC animated:YES completion:nil];
