ios - 如何在标签中添加按钮？

Question

我需要在文本末尾添加一个按钮来触发警报。文本可以分为几行 我该怎么做？

应该是这样的

Answer 1

您可以使用 NSTextAttachment 在文本末尾添加 image。

let fullString = NSMutableAttributedString(string: "Text")

// Create our NSTextAttachment
let imageAttachment = NSTextAttachment()
imageAttachment.image = UIImage(named: "awesomeIcon.png")

// Wrap the attachment in its own attributed string so we can append it
let imageString = NSAttributedString(attachment: imageAttachment)

// Add the NSTextAttachment
fullString.append(imageString)

// Draw the result in a label
yourLabel.attributedText = fullString

然后添加 UITapGestureRecognizer 以在点击后触发 Action 。

let tapGesture = UITapGestureRecognizer.init(target: self, action: #selector(showAlert(tapGesture:)))
yourLabel.addGestureRecognizer(tapGesture)

@objc func showAlert(tapGesture: UITapGestureRecognizer){
    // Show alert
}
