UITextContainerView hidding clickable link of UITextView - ios

Question

I made a clickable link in a UITextView using NSMutableAttributeString.
All it changes is that the text is highlighted
As we can see : floating over my UITextView there is a UIContainerView (I really don't know if its because of that.. I'm trying)
Here is my UIView code:
class InfoBox: UIView {
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
}()}
The NSAttributedString 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 = [NSLinkAttributeName: NSURL(string: linkURL)!]
attributedText.addAttributes(attrib, range: textRange)
}
return attributedText
}
And this is how it is called:
self.TelBox.TextContent.attributedText = transformText(text: self.TelBox.TextContent.text, underlined: true, linkURL: "https://www.google.fr")
Secondary question : is it possible to make a clickable link in a UITextView for a telephone number so that when clicked it calls that number? Did it with a UIButton .

Answer 1

I am not sure what is wrong with your UIContainerView, as far as i can see there's nothing wrong there.
Here's the method to make the link call a number:
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
}
You can use it like this: TextContent.attributedText = transformText(text: "12345", underlined: true, phoneNumber: "12345")
