Turn some parts of UILabel to act like a UIButton? [duplicate]

Answer 1

What you want to do is use an attributed string with a text view to make a link that will act as a button.

let attributedString = NSMutableAttributedString(string: "Some string with link", attributes: [])

Then set a part of it as a link, and customize it's appearance using the linkAttributes property of the Text View. Because this is a button and not an actual link we just put a dummy url in for the link so we can handle it in our delegate later.

attributedString.setSubstringAsLink(substring: "link", linkURL: "CUSTOM://WHATEVER")
let linkAttributes: [String : AnyObject] = [NSForegroundColorAttributeName : .redColor(), NSUnderlineColorAttributeName : .redColor(), NSUnderlineStyleAttributeName : NSUnderlineStyle.StyleSingle.rawValue]
textView.linkTextAttributes = linkAttributes
textView.attributedText = attributedString
textView.selectable = true
textView.editable = false
textView.userInteractionEnabled = true

Finally in text view delegate we will check for the scheme and perform some action.

func textView(textView: UITextView, shouldInteractWithURL URL: NSURL, inRange characterRange: NSRange) -> Bool {
    if URL.scheme == "CUSTOM" {
       // Do your button actions here
    }
    return true
}

Extension for setSubstringAsLink:

extension NSMutableAttributedString {
    // Set part of string as URL
    public func setSubstringAsLink(substring substring: String, linkURL: String) -> Bool {
        let range = self.mutableString.rangeOfString(substring)
        if range.location != NSNotFound {
            self.addAttribute(NSLinkAttributeName, value: linkURL, range: range)
            return true
        }
        return false
    }
}
