在UINavigationController上创建后箭头形状leftBarButtonItem [英] creating back arrow shaped leftBarButtonItem on UINavigationController

问题描述

我有一个导航控制器的视图，我以模态方式显示，我想添加一个形状类似于大多数splitViewControllers中使用的默认左箭头按钮的后退按钮。

I have a view with a navigation controller that I am showing modally and I want to add a back button that is shaped like the default left arrow buttons used in most splitViewControllers.

我可以创建一个基本按钮，但我真的想要左箭头形状 - 这就是我现在所拥有的：

I can create a basic button but I really want the left arrow shape - here is what i have now:

/* set title and nav bar items */
self.navigationItem.leftBarButtonItem = [[[UIBarButtonItem alloc] initWithTitle:@"Back To Thumbnails" style:UIBarButtonItemStylePlain target:self action:@selector(backToThumbnails:)] autorelease];

我这里只看到了3种风格选项？任何建议都非常感谢！

I only saw 3 options for style here? Any suggestions are greatly appreciated!

推荐答案

不幸的是，创建一个这样的按钮不是公共API的一部分，你需要制作一个自定义的带图像的UIBarButton 。

Unfortunately creating a button like that is not apart of the public API, you'll need to make a custom UIBarButton with an image.
