在 UINavigationController 上创建返回箭头形状的 leftBarButtonItem

问题描述

我有一个带有导航控制器的视图，我正在模态显示，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 - 这是我现在拥有的:

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];

我在这里只看到了 3 个样式选项?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，创建这样的按钮不属于公共 API，您需要自定义 带有图像的 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.
