NSMutableAttributedString 中的可点击 link 需要显示另一个 viewcontroller / 故事板

Clickable link within NSMutableAttributedString needs to show another viewcontroller / storyboard

我有一个 UITextView 和一个可点击的 NSMutableAttributedString link。我需要这个来展示另一个故事板,但不太确定我该怎么做。

到目前为止,我所拥有的适用于外部 link,但不适用于故事板。任何帮助将不胜感激。

不确定下面的代码是否是处理它的最佳方法?

class HomeViewController: UIViewController {

    @IBOutlet weak var textView: UITextView!

    override func viewDidLoad() {
        super.viewDidLoad()

        let attributedString = NSMutableAttributedString(string: "Already have an account? Log in")
        attributedString.addAttribute(.link, value: "", range: NSRange(location: 25, length: 6))

        textView.attributedText = attributedString

    }

    func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange, interaction: UITextItemInteraction) -> Bool {
        UIApplication.shared.open(URL)

        return false
    }


}

编辑

在 NikR 回答后,我已将我的代码更新为以下内容,但仍然没有成功。它仍在加载 Google。

class HomeViewController: UIViewController, UITextViewDelegate {

    @IBOutlet weak var textView: UITextView!

    override func viewDidLoad() {
        super.viewDidLoad()

        let attributedString = NSMutableAttributedString(string: "Already have an account? Log in")
        attributedString.addAttribute(.link, value: "https://google.com", range: NSRange(location: 25, length: 6))

        textView.attributedText = attributedString
        textView.isSelectable = true
        textView.isEditable = false

        textView.delegate = self

    }

    func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange, interaction: UITextItemInteraction) -> Bool {

        let loginViewController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "loginViewController")
        show(loginViewController, sender: self)

        return true
    }


}

是的,这是正确的方法。 但不打电话:

UIApplication.shared.open(URL)

只需启动您的 VC 和 show/present 它:

let vc = UIStoryboard(name: "StoryboardName", bundle: nil).instantiateInitialViewController()
show( vc, sender: self )

别忘了:

textView.delegate = self

你可以设置为你的textView:

textView.dataDetectorTypes = .link

您应该为文本视图启用 isSelectable 并禁用 isEditable。

textView.isSelectable = true
textView.isEditable = false

别忘了这样做

textView.delegate = self

此委托方法将用于处理点击

func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange, interaction: UITextItemInteraction) -> Bool {

}
