问题描述
我想使用Xcode 11中的“可注册链接”将其显示为可点击链接：
此情节提要中的所有按钮均已在情节提要中创建。我遇到了一个涉及编码的解决方案...
override func viewDidLoad() {
let attributedString = NSMutableAttributedString(string: "Don't have an account? Sign up.")
attributedString.addAttribute(.link,value: "https://udacity.com",range: NSRange(location: 23,length: 8))
webSignUp.attributedText = attributedString
}
func textView(_ textView: UITextView,shouldInteractWith URL: URL,in characterRange: NSRange,interaction: UITextItemInteraction) -> Bool {
UIApplication.shared.open(URL)
return false
}
...但是这会使我已经创建的按钮消失。
如何使用Xcode 11在情节提要中创建链接？还是在编码中创建一个不会干扰其他所有内容的链接？
解决方法
使用 TextEdit.app 这个管理RichText的小应用程序，可以将其用于属性字符串和故事板。
打开应用程序，编写文本，选择需要链接的文本部分。 编辑/添加链接... ，添加您的链接。
打开 Xcode.app ，在 Storyboard 中选择 UITextView ，然后从 TextEdit.app复制/粘贴文本放入 UITextView 。
由于有时 WYSIWYG 可能很奇怪，并且Xcode根本不是用户友好的，所以请右键单击情节提要，打开为/源代码 >，找到您的文字（您可以搜索key="NSLink"，也可以只搜索您输入的文字，链接等）
您应该看到：

这非常冗长，尤其是所有的tabstop / textTab，但是您可以从那里编辑上下文（例如更改链接）。
