如何获取文本在backBarButtonItem？ [英] How to get the text in a backBarButtonItem?

问题描述

有没有人知道如何在使用UINavigationController时获取backBarButtonItem的文本内容？这是上一个视图的名称，但我想在下一个视图中获得它。

谢谢！

解决方案>

这里有一种方法可以在导航控制器viewController堆栈中获得上一个viewController的标题：

 （（UIViewController * ）[self.navigationController.viewControllers objectAtIndex：self.navigationController.viewControllers.count-2]）。title 
  

does anyone knows how to get the text content of a backBarButtonItem when using a UINavigationController ? It's the name of the previous view but I'd like to get it in the next view.

Thanks!

解决方案

Here's one way to get the title of the previous viewController in the navigation controller viewController stack:

((UIViewController*)[self.navigationController.viewControllers objectAtIndex:self.navigationController.viewControllers.count-2]).title
