我正在尝试在 MPMoviePlayerViewController 的 navigationcontroller.view 上添加按钮。到目前为止，我已经写了以下内容。它没有给出任何错误，但按钮没有出现在视图中！谁能告诉我我做错了什么？谢谢。

        MPMoviePlayerViewController *videoController = [[[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL URLWithString:filePath]] autorelease];
        UIButton *favButton = [UIButton buttonWithType:UIButtonTypeCustom];
        favButton.frame = CGRectMake(280, 25, 30, 30);
        [favButton addTarget:self action:@selector(favouriteButtonClicked:) forControlEvents:UIControlEventTouchUpInside];
    [favButton setBackgroundImage:[UIImage imageNamed:@"unselected.png"] forState:UIControlStateNormal];
        [videoController.navigationController.view addSubview:favButton];
        [self presentMoviePlayerViewControllerAnimated:videoController];


- (void)favouriteButtonClicked:(id)sender
{
    NSLog(@"Inside favourite button clicked");
}

也尝试使用以下代码添加，但没有运气！

        UIBarButtonItem *button = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(favouriteButtonClicked:)]; 
        videoController.navigationController.navigationItem.rightBarButtonItem=button; 
        [button release];

如果您使用presentModalViewController，则看不到您添加的按钮。你必须 [self.navigationController pushViewController:moviePlayer animated:YES] 才能看到它。
