ios - 覆盖 iOS 上的 "Look Up"菜单项

Question

当您在 iOS 中选择文本时，其中一个菜单项称为“查找”。

是否可以覆盖此行为并显示您自己的 View Controller ？

Answer 1

您可以覆盖这些命令并通过 UIMenuController 和 UIMenuItem 类提供自定义控件:

UIMenuItem

With iOS 3.2, developers could now add their own commands to the menu controller. As yet unmentioned, but familiar commands like “Define” or spell check suggestions take advantage of this.

UIMenuController has a menuItems property, which is an NSArray of UIMenuItem objects. Each UIMenuItem object has a title and action. In order to have a menu item command display in a menu controller, the responder must implement the corresponding selector.
