위와 같은 에러가 나옵니다.  
말인 즉슨 modal view controller 가 아니면 사용할수가 없다는 군요 ;ㅂ;

그래서 코드는 아래로 옮겨 주고, present modal 로 보여줬습니다.

- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];
    
    TWTweetComposeViewController *composeViewController = [[TWTweetComposeViewController alloc] init];
    [self presentModalViewController:composeViewController animated:YES];
    [composeViewController release];
}
