ios - 如何创建标准的 iOS 分享按钮？

Question

The iOS Human Interface Guidelines say :

Use the system-provided Share button. Users are familiar with the meaning and behavior of this button, so it’s a good idea to use it when possible. The main exception to this is if your app does not contain a toolbar or navigation bar[, as] the Share button can only be used in a toolbar or navigation bar.

好的，但是如何“使用系统提供的分享按钮”？ A search of the documentation没有任何用处。

我收集到 I should use UIActivityViewController in my response to the button being tapped ，但我首先要如何创建标准的共享按钮？

Answer 1

标准的共享按钮是一个 UIBarButtonItem(因此它只能出现在导航栏或工具栏上)。你需要create a “system item” ;具体来说，an “action item” . “操作”栏按钮项是共享按钮。
