iPad标题栏。导航栏或工具栏？ [英] iPad title bars. Navbars or toolbars?

问题描述

我看到一堆适用于iPad的应用程序非常棒的标题栏。这些似乎是导航栏和工具栏的组合。他们通常有一个后退按钮和一个标题以及男人的其他按钮。导航栏仅支持左项，右项和标题视图。而工具栏并不真正支持后退按钮或标题。

I see a bunch of apps for iPad with really cool title bars. These seem to be a combination of a navigation bar and a toolbar. They usually have a back button and a title as well as men other buttons. And a navbar only supports a left item, a right item and and title view. And the toolbar does not really support back buttons or titles.

那么如何在我的UINavigationController驱动的应用程序中使用许多按钮实现这些丰富的导航栏？

So how do I implement these rich navbars with many buttons on my UINavigationController driven application?

推荐答案

您可以通过在 UINavigationItem 中添加 UIToolbar 来获得此效果，如下所示：

You can get this effect by putting a UIToolbar in your UINavigationItem like so:

self.navigationItem.title = @"My Title";    


UIToolbar *tb = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 100, 44)];
tb.items = [NSArray arrayWithObjects:button1,button2,button3,nil];

UIBarButtonItem *tbItem = [[UIBarButtonItem alloc] initWithCustomView:tb];
self.navigationItem.rightBarButtonItem = tbItem;

[tbItem release];
[tb release];
