iPad - 多个 UIBarButtonItem

我有 UINavigationController 并将 UIListView 放置在其中。现在我想在导航栏的左侧添加多个 BarButton。这怎么可能？我设法通过代码在那里添加一个按钮，但不是多个。

编辑：通过 IB 添加到 UINavigationController 的 NavigationBar 的按钮根本不可见。什么可能导致问题？

我在 .h 文件中创建了 UINavigationController 并在 .m 中使用了它并推送了另一个视图（即 TableView）：

navigationController = [[UINavigationController alloc] init];
[window addSubview:[navigationController view]];

tableOfContents *tableOfContentsViewController = [[tableOfContents alloc] init];
[navigationController pushViewController:tableOfContentsViewController animated:NO];
[tableOfContentsViewController release];

编辑 2： 我解决了第二个问题。所以只剩下第一个问题了。多个 BarButtonItems ...

原文

I have UINavigationController and I`ve placed UIListView in it. Now I want to add multiple BarButtons to left side of navigation bar. How is that possible? I managed to add one button there via code but not multiple.

Edit: Buttons added via IB to NavigationBar of UINavigationController aren`t visible at all. What could cause the problem?

I`ve created UINavigationController in .h file and used this in .m and pushed another view (that TableView):

navigationController = [[UINavigationController alloc] init];
[window addSubview:[navigationController view]];

tableOfContents *tableOfContentsViewController = [[tableOfContents alloc] init];
[navigationController pushViewController:tableOfContentsViewController animated:NO];
[tableOfContentsViewController release];

Edit 2: I solved second problem. So the first question only remains. Multiple BarButtonItems ...
