Answer 1

Try this: if you want only facebook icon to share:

-(IBAction)shareButtonPressed:(id)sender { NSLog(@"shareButton pressed");

NSString *texttoshare = _txt;
UIImage *imagetoshare = _img;
NSArray *activityItems = @[texttoshare, imagetoshare];    
UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:nil];
activityVC.excludedActivityTypes = @[UIActivityTypeAssignToContact, UIActivityTypePrint, UIActivityTypePostToTwitter, UIActivityTypePostToWeibo];
[self presentViewController:activityVC animated:TRUE completion:nil];
}

//in the list of excluded activity type insert any other kind of activitytypes you want to exclude
