从剪贴板读取字符串

Question

如何从剪贴板中读取字符串并将其写在按钮的标题上？我可以将字符串复制到剪贴板：

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

但是如何从剪贴板中读取该字符串并将其分配给String？

Answer 1

只需将其读回如下变量：

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