我该如何使用Swift进行程序化粘贴？

Question

我希望有一个按钮，用户可以按下该按钮，将剪贴板中的任何文本自动粘贴到UITextView中。

我该如何在Swift中实现呢？

有人已经在此处回答了此问题，但是使用的是Objective-C。

你应该只需要将它们转换为Swift：

@IBAction func copy() {
    let pb: UIPasteboard = UIPasteboard.generalPasteboard();
    pb.string = textView.text // Or another source of text
}

@IBAction func paste() {
    let pb: UIPasteboard = UIPasteboard.generalPasteboard();
    textView.text /*(Or somewhere to put the text)*/ = pb.string
}

Swift 5 let pb: UIPasteboard = UIPasteboard.general 可以翻译为：let pb: UIPasteboard = UIPasteboard.general。 - spacecash21

您可以在Swift中实现复制和粘贴方法，如下所示：

您可以在Swift中实现复制和粘贴方法，如下所示：

// Function receives the text as argument for copying
func copyText(textToCopy : NSString)
{
    let pasteBoard    = UIPasteboard.generalPasteboard();
    pasteBoard.string = textToCopy; // Set your text here
}

// Function returns the copied string
func pasteText() -> NSString
{
    let pasteBoard    = UIPasteboard.generalPasteboard();
    println("Copied Text : \(pasteBoard.string)"); // It prints the copied text
    return pasteBoard.string!;
}

对于Swift 5.0及以上版本

func copyText(from text: String) {
    weak var pb: UIPasteboard? = .general
    pb?.string = text
}

func pasteText() -> String? {
    weak var pb: UIPasteboard? = .general
    
    guard let text = pb?.string else { return nil}
    
    return text
}

最简单的方法 - Swift 5+

添加任何标准的Swift类型的简单方法是使用setter：

UIPasteboard.general.string = "Pasted String"
