如何使用 Swift 将文本复制到剪贴板/粘贴板

问题描述

我正在寻找一个简洁的示例，说明如何将文本复制到 iOS 剪贴板，然后可以在其他应用中使用/粘贴.

I'm looking for a clean example of how to copy text to iOS clipboard that can then be used/pasted in other apps.

此功能的好处是可以快速复制文本，无需传统文本复制的标准文本突出显示功能.

The benefit of this function is that the text can be copied quickly, without the standard text highlighting functions of the traditional text copying.

我假设关键类在 UIPasteboard 中，但在 他们提供的代码示例.

I am assuming that the key classes are in UIPasteboard, but can't find the relevant areas in the code example they supply.

推荐答案

如果你想要纯文本，你可以使用 string 属性.它既可读又可写:

If all you want is plain text, you can just use the string property. It's both readable and writable:

// write to clipboard
UIPasteboard.general.string = "Hello world"

// read from clipboard
let content = UIPasteboard.general.string

(从剪贴板读取时，UIPasteboard 文档 还建议您可能要先检查 hasStrings，避免导致系统在需要数据之前或数据可能不存在时不必要地尝试获取数据"，例如在使用 Handoff 时.)

(When reading from the clipboard, the UIPasteboard documentation also suggests you might want to first check hasStrings, "to avoid causing the system to needlessly attempt to fetch data before it is needed or when the data might not be present", such as when using Handoff.)
