问题描述

如何从剪贴板中读取字符串并将其写在按钮标题上?我可以使用以下命令将字符串复制到剪贴板:

How can I read a string from the clipboard and write it on a button's title? I can copy a string to the clipboard with:

UIPasteboard.generalPasteboard().string = "Hello world"

但是我如何从剪贴板读取该字符串并将其分配给字符串呢?

But how do I read that string from the clipboard and assign it to a String?

推荐答案

只需将其读回到这样的变量中即可:

Just read it back into a variable like this:

let pasteboardString: String? = UIPasteboard.general.string
if let theString = pasteboardString {
    print("String is \(theString)")
}
