ios - 如何以编程方式获取 iOS 上粘贴板内容的来源

Question

在 iOS 14 上，当用户在另一个应用程序上复制/粘贴内容时，会显示一条通知，其中包含粘贴板内容来自的应用程序的名称:

是否可以以编程方式获取此信息？
例如，如果用户在 Safari 上复制链接并将其粘贴到我的应用程序中，应用程序是否可以知道粘贴板内容来自 Safari ？
我在 UIPasteboard 或 UIPasteConfiguration 文档中没有找到类似的内容。

Answer 1

似乎没有 API 来获取 owner谁把元素放在 pasteboard .
来自 documentation :

Pasteboard Owner and Items

The object that last put data onto thepasteboard is referred to as the pasteboard owner. Each piece of dataplaced onto a pasteboard is considered a pasteboard item. Thepasteboard can hold single or multiple items. Apps can place orretrieve as many items as they wish. For example, say a user selectionin a view contains both text and an image. The pasteboard lets youcopy the text and the image to the pasteboard as separate items. Anapp reading multiple items from a pasteboard can choose to take onlythose items that it supports (the text, but not the image, forexample).

addItems方法，没有(或者我可能找不到)任何名为 owner 的属性.
