问题描述
限时送ChatGPT账号..
你知道如何在 UINavigationController 中隐藏返回"按钮吗?还有，怎么显示回来，不过我想这和隐藏很相似……
Do you know how to hide the 'back' button in a UINavigationController?
Also, how to show it back, but I guess that's very similar to hiding it...
就像您在查看电子邮件时点击编辑"时 iPhone 上的邮件应用程序一样.
Just like the mail application does on the iPhone when you hit 'Edit' while viewing emails.
推荐答案
我刚刚找到答案，在控制器中使用这个:
I just found out the answer, in a controller use this:
[self.navigationItem setHidesBackButton:YES animated:YES];
然后恢复它:
[self.navigationItem setHidesBackButton:NO animated:YES];

[更新]
斯威夫特 3.0:
self.navigationItem.setHidesBackButton(true, animated:true)
