ios - UITextContainerView 隐藏 UITextView 的可点击链接
<p><p>我使用 NSMutableAttributeString 在 UITextView 中创建了一个可点击的链接。
它所改变的只是文本被突出显示</p>
<p> <a href="/image/VxbHc.png" rel="noreferrer noopener nofollow"><img src="/image/VxbHc.png" alt="The link is on the telephone number"/></a> </p>
<p> <a href="/image/Bwj01.png" rel="noreferrer noopener nofollow"><img src="/image/Bwj01.png" alt="DEBUGGER"/></a>
正如我们所看到的:漂浮在我的 UITextView 上的是一个 UIContainerView(我真的不知道是不是因为这个......我正在尝试)</p>
<p>这是我的 UIView 代码:
类信息框:UIView {</p>
<pre><code>let Heading: UITextView = {
let textView = UITextView(frame: CGRect(x: 15, y: 0, width: 200, height: 35))
textView.font = UIFont.systemFont(ofSize: 20)
textView.textColor = UIColor.white
textView.isScrollEnabled = false
textView.backgroundColor = UIColor.clear
textView.isEditable = false
textView.isSelectable = true
return textView
}()
let TextContent: UITextView = {
let textView = UITextView(frame: CGRect(x: 15, y: 27, width: UIScreen.main.bounds.width, height: 30))
textView.font = UIFont.systemFont(ofSize: 17)
textView.textColor = UIColor.white
textView.isScrollEnabled = false
textView.backgroundColor = UIColor.clear
textView.isEditable = false
textView.isSelectable = true
return textView
}()}
</code></pre>
<p>NSAttributedString 代码:</p>
<pre><code> func transformText(text: String, underlined: Bool, linkURL: String) -> NSAttributedString {
let textRange = NSMakeRange(0, text.characters.count)
let attributedText = NSMutableAttributedString(string: text)
if underlined{
attributedText.addAttribute(NSUnderlineStyleAttributeName , value: NSUnderlineStyle.styleSingle.rawValue, range: textRange)
attributedText.addAttribute(NSUnderlineColorAttributeName , value: UIColor.lightGray, range: textRange)
}
attributedText.addAttribute(NSFontAttributeName , value: UIFont(name: "Helvetica-Light", size: 17)!, range: textRange)
attributedText.addAttribute(NSForegroundColorAttributeName , value: UIColor.lightGray, range: textRange)
if(linkURL != "")
{
let attrib =
attributedText.addAttributes(attrib, range: textRange)
}
return attributedText
}
</code></pre>
<p>这就是它的名称:</p>
<pre><code> self.TelBox.TextContent.attributedText = transformText(text: self.TelBox.TextContent.text, underlined: true, linkURL: "https://www.google.fr")
</code></pre>
<p>第二个问题:是否可以在 UITextView 中为电话号码创建可点击链接，以便在点击时调用该号码？用 UIButton 做的。</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>我不确定您的 <code>UIContainerView</code> 有什么问题，据我所知没有任何问题。</p>
<p>这是使链接调用数字的方法:</p>
<pre><code>func transformText(text: String, underlined: Bool, phoneNumber: String) -> NSAttributedString {
let textRange = NSMakeRange(0, text.characters.count)
let attributedText = NSMutableAttributedString(string: text)
if underlined{
attributedText.addAttribute(NSAttributedStringKey.underlineStyle , value: NSUnderlineStyle.styleSingle.rawValue, range: textRange)
attributedText.addAttribute(NSAttributedStringKey.underlineColor , value: UIColor.lightGray, range: textRange)
}
attributedText.addAttribute(NSAttributedStringKey.font , value: UIFont(name: "Helvetica-Light", size: 17)!, range: textRange)
attributedText.addAttribute(NSAttributedStringKey.foregroundColor , value: UIColor.lightGray, range: textRange)
if(phoneNumber != "")
{
let attrib = [
NSAttributedStringKey.link: URL(string: "tel://" + phoneNumber.replacingOccurrences(of: " ", with: ""))]
attributedText.addAttributes(attrib, range: textRange)
}
return attributedText
}
</code></pre>
<p>你可以这样使用它:<code>TextContent.attributedText = transformText(text: "12345", underlined: true, phoneNumber: "12345")</code></p></p>
