Why don't you just pass the delegate to the method:

void DisplayAlert(NSString* title, NSString* message, id delegate) {

    UIAlertView *theAlert = [[[UIAlertView alloc] initWithTitle:@"Share"
                                                        message:message
                                                       delegate:delegate
                                              cancelButtonTitle:@"Cancel"
                                              otherButtonTitles:@"Notes", @"Bookmark", @"Facebook",@"Twitter",@"Email", nil] autorelease];
    [theAlert show];
}

Your code for displaying alert looks fine. Check if you have by mistake used the keyword self as some variable name.
