Describe the bug If a string contains emoji then crash unexpectedly at Truncation.swift file line of code:

let originalLine = lines[originalIndex]

Please fix this issue as soon as possible.

First off, thanks so much for making an awesome looking label replacement. In our app I'm currently doing a lot of work to manually calculate sizes in a UITextview for fields rendering markdown. I think this might be a great replacement if I can work out some of the kinks.

I'm currently using this to try to make something like this:

Anyway, thanks in advance for making it, and hopefully it's just user error on my part.

Describe the bug Cannot get a link to trigger the delegate didSelectLink callback.

To Reproduce Create a view controller and add code like this:

class ViewController: UIViewController {

    var termsAndConditionsLabel: NantesLabel!


    // MARK: - Life Cycle
    override func viewDidLoad() {
        super.viewDidLoad()
        setupTermsLabel()
    }

    // MARK: - Setup
    private func setupTermsLabel() {
        termsAndConditionsLabel = NantesLabel(frame: .zero)
        termsAndConditionsLabel.numberOfLines = 0
        view.insertSubview(termsAndConditionsLabel, aboveSubview: stackView)
        termsAndConditionsLabel.snp.makeConstraints { $0.top.equalToSuperview().offset(100); $0.left.equalToSuperview(); $0.right.equalToSuperview() }
        let termsText = "I understand by tapping \"Sign up\" my information will be used as described here and in the Privacy Policy, and I agree to the Terms."
        termsAndConditionsLabel.delegate = self
        termsAndConditionsLabel.text = termsText
        let url = URL(string: "https://www.google.com")!
        let privacyPolicyText = "Privacy Policy"
        let privacyPolicyRange = (termsText as NSString).range(of: privacyPolicyText)
        termsAndConditionsLabel.addLink(to: url, withRange: privacyPolicyRange)
    }
}

extension ViewController: NantesLabelDelegate {
    func attributedLabel(_ label: NantesLabel, didSelectLink link: URL) {
        print(link)
    }
}

Expected behavior I expected to see the link that was tapped printed to the console.

Is your feature request related to a problem? Please describe. In my code I want to have a button for Read more that pops a full text description into a new page. It would be nice to know if the label is currently displaying all the text so that I can determine whether or not to hide the Read more button

Describe the solution you'd like I think it should be possible to have a variable on the label class that gets updated in the drawAttributedString(... function that tells if the text is fully displayed. I would be happy to create a class with a PR to add this functionality if this solution makes sense. I'm open to any bikeshedding about the property name. I think isTruncated, isShowingFullText, hasHiddenText could all be possibilities. Specifically, I think that we could put a flag before the for loop and then an update somewhere in here to update the status of that flag and update the label property after looping.

//  ==> var showsFullText = true
for lineIndex in 0..<lineOrigins.count {
   // ...
    if lineIndex == numberOfLines - 1 &&
        truncateLastLine &&
        !(lastLineRange.length == 0 && lastLineRange.location == 0) &&
        lastLineRange.location + lastLineRange.length < textRange.location + textRange.length {
        let truncationDrawingContext = TruncationDrawingContext(attributedString: attributedString, context: context, descent: descent, lastLineRange: lastLineRange, lineOrigin: lineOrigin, numberOfLines: numberOfLines, rect: rect)
//  ==> showsFullText = false
        drawTruncation(truncationDrawingContext)
    } else { // otherwise normal drawing here
        let penOffset = CGFloat(CTLineGetPenOffsetForFlush(line, flushFactor, Double(rect.size.width)))
        let yOffset = lineOrigin.y - descent - font.descender
        context.textPosition = CGPoint(x: penOffset, y: yOffset)
        CTLineDraw(line, context)
    }
}
//  ==> self.showsFullText = showsFullText

Describe alternatives you've considered It is possible to use a helper function to get the height of a view with a font size / attributed string, but it seems like there is a performance overhead and extra surface area that could potentially be removed.

Hi,

Please support the newer release 0.0.9 for cocoapods. Please find the below logs:

[!] CocoaPods could not find compatible versions for pod "Nantes": In Podfile: Nantes (= 0.0.9)

None of your spec sources contain a spec satisfying the dependency: Nantes (= 0.0.9).

You have either:

• out-of-date source repos which you can update with pod repo update or with pod install --repo-update.
• mistyped the name or version.
• not added the source repo that hosts the Podspec to your Podfile.

1. set attributedText to NantesLabel, include font, linespace;
2. Get height by func boundingRect, could not get right height
3. When I replace NantesLabel to UILabel, can get the right height

Hello, you did a fix related to this #15 issue and it is working fine only when attributed string contains URL as link. And as confirmation you can see this code:

extension NSAttributedString {
    func findExistingLinks() -> Set<NSTextCheckingResult> {
        var relinks: Set<NSTextCheckingResult> = []
        enumerateAttribute(.link,
                           in: NSRange(location: 0, length: length),
                           options: []) { attribute, linkRange, _ in
                            if let url = attribute as? URL {
                                relinks.insert(NSTextCheckingResult.linkCheckingResult(range: linkRange, url: url))
                            }
        }
        return relinks
    }
}

Why you didn't allow String ? So it would be more easier if handle this scenario also:

if let linkString = attribute as? String, let url = URL(string: linkString) {

The reason - from some parsing libraries it is coming as String not as URL

Is your feature request related to a problem? Please describe. I'd love it if hyperlinks from HTML could be clicked. At the moment I construct an NSMutableAttributedString from an HTML string (built-in functionality to iOS), which colors my links but I can not click them.

Describe the solution you'd like An option to initialize NantesLabel with an HTML string so that it can parse the HTML and display clickable hyperlinks

Describe alternatives you've considered Trying to calculate the range of links but I thought that'd be too difficult.

Example String: "<a href="http://www.google.com">I can't be clicked"

Setting an attributedText value to the label that contains a .link: URL attribute does not work. This is because the checkText() method only looks at the raw string value of the attributedString for links. This means that links set that way do not work, they are not highlighted and are not clickable.

Expected behavior Not sure if I should expect NantesLabel to handle this case but it would be good if it did.

When setting the attributedText property, the attributes that can be provided by Nantes will replace the ones in the NSAttributedString. This was introduced in 4b540bc.

In my opinion it kind of defeats the purpose of having attributedText open.

A few possible solutions:

• Revert the change introduced in 0.0.5
• Make attributedText unavailable from outside
• Adjust the properties stored in NantesLabel when an attributed string is set (could be problematic as attributes can differ within the same text)

When I attempt to set a background fill or stroke, like so:

string.addAttribute(.nantesLabelBackgroundFillColor, value: UIColor.lightGray, range: range)

App crashes with:

Swift/ContiguousArrayBuffer.swift:600: Fatal error: Index out of range

The termination point is Drawing.swift:198, when accessing origins[lineIndex].x: runBounds.origin.x = origins[lineIndex].x + rect.origin.x + xOffset - fillPadding.left - rect.origin.x

I have verified that the NSRange I provide in the addAttribute call is valid, as I can use the nantesLabelStrikeOut attribute and it works fine.

Hello 👋, First of all, thank you for your library. I wanted to ask why the label textColor/font doesn't change after setting text property. for example:

// this will work ✅               // this will not work ❌

label.textColor = .red                label.text = "test"
label.text  = "test"                  label.textColor = .red

Is there a function to update the label UI ?

I'm not sure why, but in my project the didSelectLink delegate method is never called. It seems that the root cause is that touchesEnded is also never called inside of NantesLabel, only touchesBegan and touchesCancelled.

In my case the label is used within a UIStackView within a UITableViewCell, auto-sizing everything. I set myLabel.attributedText to an instance of NSAttributedString with the .foregroundColor and .font attributes set, and links are added the old-fashioned way via NSMutableAttributedString's addAttribute. The links are styled just fine (via linkAttributes), so they are definitely recognized. Also within touchesBegan I can see that it does find the link and sets activeLink. But.. touchesEnded is never called, so handleLinkTapped is also never executed.

I'm not sure how easy it's going to be to make a minimum reproducible project 😰 But I'll see what I can do!

As the Title said. I have a feature that when I long press the link, I can show an action sheet. I think it's a common feature, so is there any method supports long press gesture? Like the property called 'linkLongPressBlock' in TTTAttributedLabelLink
