Multi-line NSAttributedString with truncated text

I need a UILabel subcass with multiline attributed text with support for links, bold styles, etc. I also need tail truncation with an ellipsis. None of the open source code that supports attributed text inside UILabels (TTTAttributedLabel, OHAttributedLabel, TTStyledTextLab开发者_运维知识库el) seem to support tail truncation for multi-line text. Is there an easy way to get this?

---

Maybe I'm missing something, but whats wrong with? :

NSMutableAttributedString *text = [[NSMutableAttributedString alloc] initWithString:@"test"];

NSMutableParagraphStyle *style = [[NSMutableParagraphStyle alloc] init];
style.lineBreakMode = NSLineBreakByTruncatingTail;
[text addAttribute:NSParagraphStyleAttributeName
                      value:style
                      range:NSMakeRange(0, text.length)];

label.attributedText = text;

This works perfectly and will add a ellipsis to the end.

Hi I am the developer of OHAttributedLabel.

There is no easy way to achieve this (as explained in the associated issue I opened on the github repository of my project), because CoreText does not offer such feature.

The only way to do this would be to implement the text layout yourself using CoreText objects (CTLine, etc) instead of using the CTFrameSetter that does this for you (but w/o managing line truncation). The idea would be to build all the CTLines to lay them out (depending on the glyphs in your NSAttributedString it contains and the word wrapping policy) one after the other and manage the ellipsis at the end yourself.

I would really appreciate if someone propose a solution to do this propery as it seems a bit of work to do and you have to manage a range of special/unusual cases too (emoji cases, fonts with odd metrics and unusual glyphs, vertical alignment, take into account the size of the ellipsis itself at the end to know when to stop).

So feel free to dig around and try to implement the framing of the lines yourself it would be really appreciated!

Based on what I found here and over at https://groups.google.com/forum/?fromgroups=#!topic/cocoa-unbound/Qin6gjYj7XU, I came up with the following which works very well.

- (void)drawString:(CFAttributedStringRef)attString inRect:(CGRect)frameRect inContext:    (CGContextRef)context
{
CGContextSaveGState(context);

// Flip the coordinate system
CGContextSetTextMatrix(context, CGAffineTransformIdentity);
CGContextTranslateCTM(context, 0, self.bounds.size.height);
CGContextScaleCTM(context, 1.0, -1.0);

CGFloat height = self.frame.size.height;
frameRect.origin.y = (height - frameRect.origin.y)  - frameRect.size.height ;

// Create a path to render text in
// don't set any line break modes, etc, just let the frame draw as many full lines as will fit
CGMutablePathRef framePath = CGPathCreateMutable();
CGPathAddRect(framePath, nil, frameRect);
CTFramesetterRef framesetter = CTFramesetterCreateWithAttributedString(attString);
CFRange fullStringRange = CFRangeMake(0, CFAttributedStringGetLength(attString));
CTFrameRef aFrame = CTFramesetterCreateFrame(framesetter, fullStringRange, framePath, NULL);
CFRelease(framePath);

CFArrayRef lines = CTFrameGetLines(aFrame);
CFIndex count = CFArrayGetCount(lines);
CGPoint *origins = malloc(sizeof(CGPoint)*count);
CTFrameGetLineOrigins(aFrame, CFRangeMake(0, count), origins);

// note that we only enumerate to count-1 in here-- we draw the last line separately
for (CFIndex i = 0; i < count-1; i++)
{
    // draw each line in the correct position as-is
    CGContextSetTextPosition(context, origins[i].x + frameRect.origin.x, origins[i].y + frameRect.origin.y);
    CTLineRef line = (CTLineRef)CFArrayGetValueAtIndex(lines, i);
    CTLineDraw(line, context);
}

// truncate the last line before drawing it
if (count) {
    CGPoint lastOrigin = origins[count-1];
    CTLineRef lastLine = CFArrayGetValueAtIndex(lines, count-1);

    // truncation token is a CTLineRef itself
    CFRange effectiveRange;
    CFDictionaryRef stringAttrs = CFAttributedStringGetAttributes(attString, 0, &effectiveRange);

    CFAttributedStringRef truncationString = CFAttributedStringCreate(NULL, CFSTR("\u2026"), stringAttrs);
    CTLineRef truncationToken = CTLineCreateWithAttributedString(truncationString);
    CFRelease(truncationString);

    // now create the truncated line -- need to grab extra characters from the source string,
    // or else the system will see the line as already fitting within the given width and
    // will not truncate it.

    // range to cover everything from the start of lastLine to the end of the string
    CFRange rng = CFRangeMake(CTLineGetStringRange(lastLine).location, 0);
    rng.length = CFAttributedStringGetLength(attString) - rng.location;

    // substring with that range
    CFAttributedStringRef longString = CFAttributedStringCreateWithSubstring(NULL, attString, rng);
    // line for that string
    CTLineRef longLine = CTLineCreateWithAttributedString(longString);
    CFRelease(longString);

    CTLineRef truncated = CTLineCreateTruncatedLine(longLine, frameRect.size.width, kCTLineTruncationEnd, truncationToken);
    CFRelease(longLine);
    CFRelease(truncationToken);

    // if 'truncated' is NULL, then no truncation was required to fit it
    if (truncated == NULL)
        truncated = (CTLineRef)CFRetain(lastLine);

    // draw it at the same offset as the non-truncated version
    CGContextSetTextPosition(context, lastOrigin.x + frameRect.origin.x, lastOrigin.y + frameRect.origin.y);
    CTLineDraw(truncated, context);
    CFRelease(truncated);
}
free(origins);

CGContextRestoreGState(context);

}

Heres a Swift 5 version of @Toydor's answer:

let attributedString = NSMutableAttributedString(string: "my String")    
let style: NSMutableParagraphStyle = NSMutableParagraphStyle()
style.lineBreakMode = .byTruncatingTail
attributedString.addAttribute(NSAttributedString.Key.paragraphStyle,
                                      value: style,
                                      range: NSMakeRange(0, attributedString.length))

I haven't tried this in all cases, but something like this could work for truncation:

NSAttributedString *string = self.attributedString;
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextSetTextMatrix(context, CGAffineTransformIdentity);

CFAttributedStringRef attributedString = (__bridge CFTypeRef)string;
CTFramesetterRef framesetter = CTFramesetterCreateWithAttributedString(attributedString);
CGPathRef path = CGPathCreateWithRect(self.bounds, NULL);
CTFrameRef frame = CTFramesetterCreateFrame(framesetter, CFRangeMake(0, 0), path, NULL);

BOOL needsTruncation = CTFrameGetVisibleStringRange(frame).length < string.length;
CFArrayRef lines = CTFrameGetLines(frame);
NSUInteger lineCount = CFArrayGetCount(lines);
CGPoint *origins = malloc(sizeof(CGPoint) * lineCount);
CTFrameGetLineOrigins(frame, CFRangeMake(0, 0), origins);

for (NSUInteger i = 0; i < lineCount; i++) {
    CTLineRef line = CFArrayGetValueAtIndex(lines, i);
    CGPoint point = origins[i];
    CGContextSetTextPosition(context, point.x, point.y);

    BOOL truncate = (needsTruncation && (i == lineCount - 1));
    if (!truncate) {
        CTLineDraw(line, context);
    }
    else {
        NSDictionary *attributes = [string attributesAtIndex:string.length-1 effectiveRange:NULL];
        NSAttributedString *token = [[NSAttributedString alloc] initWithString:@"\u2026" attributes:attributes];
        CFAttributedStringRef tokenRef = (__bridge CFAttributedStringRef)token;
        CTLineRef truncationToken = CTLineCreateWithAttributedString(tokenRef);
        double width = CTLineGetTypographicBounds(line, NULL, NULL, NULL) - CTLineGetTrailingWhitespaceWidth(line);
        CTLineRef truncatedLine = CTLineCreateTruncatedLine(line, width-1, kCTLineTruncationEnd, truncationToken);

        if (truncatedLine) { CTLineDraw(truncatedLine, context); }
        else { CTLineDraw(line, context); }

        if (truncationToken) { CFRelease(truncationToken); }
        if (truncatedLine) { CFRelease(truncatedLine); }
    }
}

free(origins);
CGPathRelease(path);
CFRelease(frame);
CFRelease(framesetter);

How to use

    let font:UIFont = UIFont(name: "HiraMinProN-W3", size: 17.0) ?? UIFont.systemFont(ofSize: 17.0)

    override func viewDidLoad() {
        super.viewDidLoad()

        let text = "iOS 11 sets a new standard for what is already the world’s most advanced mobile operating system. It makes iPhone better than before. It makes iPad more capable than ever. And now it opens up both to amazing possibilities for augmented reality in games and apps. With iOS 11, iPhone and iPad are the most powerful, personal, and intelligent devices they’ve ever been."
        // If check for Japanese
//        let text = "すでに世界で最も先進的なモバイルオペレーティングシステムであるiOSに、iOS 11が新たな基準を打ち立てます。iPhoneは今まで以上に優れたものになり、iPadはかつてないほどの能力を手に入れます。さらにこれからはどちらのデバイスにも、ゲームやアプリケーションの拡張現実のための驚くような可能性が広がります。iOS 11を搭載するiPhoneとiPadは、間違いなくこれまでで最もパワフルで、最もパーソナルで、最も賢いデバイスです。"

        // if not vertical text, isVertical = false
        multiLineVerticalGlyphWithTruncated.setupProperties(text: text, font: font, isVertical: true)
    }
}

You may be able to use follow code to have a more simple solution.

    // last line.
    if (_limitToNumberOfLines && count == _numberOfLines-1)
    {
        // check if we reach end of text.
        if (lineRange.location + lineRange.length < [_text length])
        {
            CFDictionaryRef dict = ( CFDictionaryRef)attributes;
            CFAttributedStringRef truncatedString = CFAttributedStringCreate(NULL, CFSTR("\u2026"), dict);

            CTLineRef token = CTLineCreateWithAttributedString(truncatedString);

            // not possible to display all text, add tail ellipsis.
            CTLineRef truncatedLine = CTLineCreateTruncatedLine(line, self.bounds.size.width - 20, kCTLineTruncationEnd, token);
            CFRelease(line); line = nil;
            line = truncatedLine;
        }
    }

I'm using MTLabel in my project and it's a really nice solution for my project.

Ran into this issue here in 2021.

I wrapped @Toydor's and @gypsyDev's answer into a UILabel extension so it can be applied where needed. Swift 5.

extension UILabel {
    func ensureAttributedTextShowsTruncation() {
    
        guard let text = attributedText else { return }
    
        let attributedString = NSMutableAttributedString(attributedString: text)

        let paragraphStyle = NSMutableParagraphStyle()
        paragraphStyle.lineBreakMode = .byTruncatingTail
    
        attributedString.addAttribute(.paragraphStyle,
                                  value: paragraphStyle,
                                  range: NSRange(location: 0, length: attributedString.length))

        attributedText = attributedString
    }
}

I used as sample MTLabel. It allows to manage line height. I needed the draw method exactly, so i just put away most stuff i did not need. This method allows me to draw multilined text in rect with tail truncation.

CGRect CTLineGetTypographicBoundsAsRect(CTLineRef line, CGPoint lineOrigin)
{
CGFloat ascent = 0;
CGFloat descent = 0;
CGFloat leading = 0;
CGFloat width = CTLineGetTypographicBounds(line, &ascent, &descent, &leading);
CGFloat height = ascent + descent;

return CGRectMake(lineOrigin.x,
                  lineOrigin.y - descent,
                  width,
                  height);
}
- (void)drawText:(NSString*) text InRect:(CGRect)rect withFont:(UIFont*)aFont inContext:(CGContextRef)context {

if (!text) {
    return;
}

BOOL _limitToNumberOfLines = YES;
int _numberOfLines = 2;
float _lineHeight = 22;

//Create a CoreText font object with name and size from the UIKit one
CTFontRef font = CTFontCreateWithName((CFStringRef)aFont.fontName ,
                                      aFont.pointSize,
                                      NULL);


//Setup the attributes dictionary with font and color
NSDictionary *attributes = [NSDictionary dictionaryWithObjectsAndKeys:
                            (id)font, (id)kCTFontAttributeName,
