问题描述

从故事板中提供的导航栏中隐藏或删除特定按钮项UIBarButtonItem.

Hide OR remove specific button item from navigation bar UIBarButtonItem which is given from storyboard.

例如，右侧导航栏项目我添加了 3 个 UIBarButtonItem，例如故事板中的完成"、取消"、下一步"，现在我想从故事板中删除或隐藏取消"按钮根据用户登录以编程方式导航栏，那么我该怎么办?

For example right side navigation bar item I have added 3 UIBarButtonItem like "Done", "Cancel", "next" from storyboard and now I want to remove or Hide "Cancel" button from the navigation bar programmatically as per the user login, So what can I do for this issue?

推荐答案

试试这个:

self.navigationItem.rightBarButtonItems?.remove(at: [indexOfButton])

[indexOfButton] 应该是 rightBarButtonItems 数组中按钮的索引.

[indexOfButton] should be the index of the button in the rightBarButtonItems array.
