:link: A lightweight class for rendering text containing HTML tags on iOS 6.0+

mdhtmllabel's Issues

Line breaks are ignored

Maybe someone can help me!
I get some html Text from my Server and it should be shown on my Device like this:
"Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua.

At vero eos et accusam et justo duo dolores et ea rebum. Stet clita kasd gubergren, no sea takimata sanctus est Lorem ipsum dolor sit amet."

but instead it looks like this:
"Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua.At vero eos et accusam et justo duo dolores et ea rebum. Stet clita kasd gubergren, no sea takimata sanctus est Lorem ipsum dolor sit amet."

As you can see, there is no line break, why?

This is the Code:

 MDHTMLLabel *htmlLabel = [[MDHTMLLabel alloc] init];

  htmlLabel.delegate = self;
  htmlLabel.numberOfLines = 0;
  htmlLabel.lineBreakMode = NSLineBreakByTruncatingTail;
  htmlLabel.font = [UIFont fontWithName:@"Arial" size:12.0f];


   htmlLabel.htmlText = item.text;




   htmlLabel.linkAttributes = @{NSForegroundColorAttributeName: [UIColor blueColor],
                                     NSFontAttributeName: [UIFont boldSystemFontOfSize:htmlLabel.font.pointSize],
                                     NSUnderlineStyleAttributeName: @(NSUnderlineStyleSingle)};

    htmlLabel.activeLinkAttributes = @{NSForegroundColorAttributeName: [UIColor redColor],
                                           NSFontAttributeName: [UIFont boldSystemFontOfSize:htmlLabel.font.pointSize],
                                           NSUnderlineStyleAttributeName: @(NSUnderlineStyleSingle)};

        [self addSubview:htmlLabel];

Here is the Html Text:

 Lorem ipsum dolor sit amet, consetetur sadipscing elitr, 
 sed diam nonumy eirmod tempor invidunt ut   labore et dolore magna aliquyam erat, sed diam
 voluptua.<br /><br /> At vero eos et accusam et justo duo dolores et ea rebum. Stet clita kasd 
 gubergren, no sea takimata sanctus est Lorem ipsum dolor sit amet. Lorem ipsum dolor sit amet, 
consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna   
 aliquyam erat, sed diam voluptua.<br /><br /> At vero eos et accusam et justo duo dolores et ea 
 rebum. Stet clita kasd gubergren, no sea takimata sanctus est Lorem ipsum dolor sit amet.

<font size='XX'>

font size without font face doesn't work

Custom font removed after tap

I used to be able to include custom fonts within the text (with icon symbols), like so:
<a href=\”http://example.com\”><font face=\”customappfont\”>O</font>Open Website</a>

This still works. However, on tap, the custom font returns to whatever the main font is. So it looks like:
OOpen Website

rather than:
(symbol)Open Website

Does support html table?

The method setHtmlText has some needless code

• (void)setHtmlText:(NSString *)htmlText
  {
  if ([_htmlText isEqualToString:htmlText])
  {
  return;
  }

  _htmlText = [htmlText copy];
  _htmlAttributedText = nil;

  if (_htmlText)
  {
  //(this code seems needless( change a param). when i comment it, the demo works well)************
  // htmlText = [_htmlText stringByReplacingOccurrencesOfString:@"
  " withString:@"\n"];

    if (self.autoDetectUrls)
    {
  

//(this code seems needless(change a param), too. when i comment it, the demo works well)***********
// htmlText = [self detectURLsInText:_htmlText];
}

    [self extractStyleFromText:_htmlText];
}
else
{
    self.styleComponents = nil;
    self.plainText = nil;
    self.links = [NSMutableArray array];
}

[self setNeedsFramesetter];
[self setNeedsDisplay];
[self invalidateIntrinsicContentSize];

}

problems with certain HTML entities (ex: &lt;)

MDHTMLLabel doesn't handle HTML entities, for example < and >

Say I want to display this exact string in MDHTMLLabel:

"1 < 2, I <3 MDHTMLLabel, 2 > 1"

label.htmlText = @"1 < 2, I <3 MDHTMLLabel, 2 > 1";

You can't. You'll end up with "1 1", see the attached screen shot.

It'd expected this to work:

label.htmlText = @"1 < 2, I <3 MDHTMLLabel, 2 > 1";

But it will appear the same!

The issue is here:

https://github.com/mattdonnelly/MDHTMLLabel/blob/master/MDHTMLLabel/MDHTMLLabel.m#L1339

The code is decoding the HTML entities before it finds styles and extract links.

I think the correct fix is to move the code to decode the HTML entities to after it finds styles and extract links. But just moving the code in MDHTMLLabel to decode the HTML after we do the detection won't work, as the offsets for all the links and style components will be incorrect.

Note that RTLabel seems to have a similar bug, see honcheng/RTLabel#47

Mixing fonts in link

I want to be able to have a label with attributed text, with combined fonts. In my case, I would be using a normal font and a custom symbol font.

For instance, the text:

See your items in the (*) Favorites section

.. with (*) Favorites being a single link and (*) being a letter from a custom font.

Is there a way to do this with MDHTMLLabel?

white space appear as html row string.

if I set htmlText as <span>&nbsp;</span> it appears &nbsp in label.

The shadow is cleared

At the first, I must be thanks for your great code for us! it's very helpful！

I set some shadow on Label, and put it into a tablecell when I long click the label and move it, the shadow is cleared

I feel if set the property "Highlighted" to "NO" is not work, I must be do following

bodyLabel.highlighted = YES;
bodyLabel.highlightedShadowColor = bodyLabel.shadowColor;
bodyLabel.highlightedShadowOffset = bodyLabel.shadowOffset;
bodyLabel.highlightedShadowRadius = bodyLabel.shadowRadius;
bodyLabel.highlightedTextColor = bodyLabel.textColor;

bad HTML like "<b><b>" causes a crash

I see the crash, add to kDemoText in DemoViewController.m

MDHTMLLabelButton URL is null, if there is a unicode-character (like Korean Lang.).

MDHTMLLable.m line at 660.

linkButton.URL = [NSURL URLWithString:[linkableComponents.attributes objectForKey:@"href"]];

The URL is null if there is a unicode-character (like Korean Lang.).

So, I fixed it to

NSString *attributeUrl = [linkableComponents.attributes objectForKey:@"href"];
attributeUrl = [attributeUrl stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSURL *aUrl = [NSURL URLWithString:attributeUrl];
linkButton.URL = aUrl;

Thank you.

HTML Character "<" & ">" Parsing Issue

Hello Matt,
Thanks In Advance...
We are using MDHTMLLabel for display below html string.
You are now manager of <4070Testing>.
we have 2 scenarios..

1. by direct use above Then Application getting crash.
2. if we replace > from "<" & < from ">" like attached screen shot. return result is only "You are now manager of"

Thanks,

HTML tags: , 

I needed to use superscript/subscript but MDHTMLLabel doesn't support it, so I implemented it and though it works, it doesn't for iOS9.x. Texts are not subscripted nor superscripted. I've reviewed the code but can't make it where the problem could be.
This is the code I'm using that I implemented, showing subscript only:

- (void)applySubscriptToText:(CFMutableAttributedStringRef)text
                       range:(NSRange)range {
    /* Because Helvetica Neue doesn't handle subscript AND because CT added kCTSuperscriptAttributeName key until ios11, this code is commented out:
    CFAttributedStringSetAttribute(text, CFRangeFromNSRange(range), kCTSuperscriptAttributeName, (__bridge CFTypeRef)(@-1));
     */
    
    NSMutableAttributedString *attributedString = (__bridge NSMutableAttributedString *)(text);
    UIFont *subScriptFont = [UIFont fontWithName:self.font.fontName size:self.font.pointSize * 0.6];
    [attributedString addAttribute:NSFontAttributeName value:subScriptFont range:range];
    [attributedString addAttribute:NSBaselineOffsetAttributeName value:@(-1.5) range:range];
}

If you use iOS11 you can use the commented code and discard the rest (or you can leave the code as is and it will work for iOS > 9.x), otherwise it only works for iOS > 9.x.

Wrong alignment?

This makes it centered:

htmlLabel.textAlignment = NSTextAlignmentRight;

while this aligns it to the right:

htmlLabel.textAlignment = NSTextAlignmentCenter;

Left seems to work.

support inline image

According to current senario, I have received html string from server and i am using your library to parse html content. all things are working fine except inline image. so can you please help me how i can provide support to display inline image in UILabel?

Thanks in advance

When to support inline image?

the html tag should support? thanks.

memory problems

i'm having memory problems allocating MDHTMLLabels in TableCellViews.
have you experience this kind of errors?

Disabled email detection

Can I configured the Label to not detect the emails because it is adding the "mailto:" and don't want this.

Thanks

NSLineBreakByTruncatingTail showing only one line

When I add the line break mode NSLineBreakByTruncatingTail, the label is only showing one line of the text. But the label has enough space to view 3 lines and truncate only the last line of text.
(see image, red is the MDHTMLLabel with NSLineBreakByTruncatingTail)

Typo fix

I noticed a typo in your README file. I’ve highlighted it in bold italics for your convenience below.

…links inside the label to represent HTML _achor_ tags and allows you to detect…

certain HTML will cause out of memory errors, infinite loop

MDHTMLLabel is great, thank you!

But HTML like this will cause problems:

<a href='http://www.google.com'>google.com</a>

On my console:

We'll run out of memory.

looks like [MDHTMLLabel detectURLsInText] has a bug and we get stuck incorrectly wrapping a url over and over.

I've got a patch, I'll make a pull request to see what you think.

Demo compile error

Replace 'MDHTMLLabel/MDHTMLLabel-Prefix.pch' with 'Demo/MDHTMLLabelDemo-Prefix.pch' in Build Settings ->Apple LLVM 6.0 Language ->Prefix Header

<custom tags>

thanks for the update, it's works really good.

i'm thinking now in the idea of create , with user defined attributes.

i'm playing with your code and it seems to be easy to implement it.
you write a good code objectiveC code.
i'm not an objectiveC developer, i'm feel more confortable in ruby (rubymotion)

thanks again for share your code, it's great.

Feature request: url with background

Is it possible to add a feature so you can add a background color to an url? So the url is highlighted.

Too long text makes label invisible?

Hi I've tried displaying some very large texts with MDHTMLLabel (about 24000 characters) and the result was a blank.
I have the label inside a scrollview and I could get the correct content height (from sizeToFit) so that I could scroll to read everything.
The text was nowhere to be seen, although I could scroll to the end (to where it should be).

I also tried setting the background color to see the label bounds, but the label doesn't show up at all.
Also, reducing the amount of characters (to about 21000-22000) seems to work ok.

Any ideas?
Thanks!

specific key-value causes crash!

hi, i got a crash when i parse such html ＜img alt="" src="about:blank" /＞ ...

as you see, alt="", so when the code goes to the extractStyleFromText method,
the follow codes in line 1460 may causes crash:
value = [value stringByReplacingOccurrencesOfString:@""" withString:@"" options:NSLiteralSearch range:NSMakeRange(0, 1)];
value = [value stringByReplacingOccurrencesOfString:@""" withString:@"" options:NSLiteralSearch range:NSMakeRange([value length]-1, 1)];
// After the two statements ran, the value will be EMPTY, so the next line will CAUSES CRASH...
value = [value stringByReplacingOccurrencesOfString:@"'" withString:@"" options:NSLiteralSearch range:NSMakeRange(0, 1)];
value = [value stringByReplacingOccurrencesOfString:@"'" withString:@"" options:NSLiteralSearch range:NSMakeRange([value length]-1, 1)];
value = [value stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];

My solution is subclass your label and override this method replace them by:

value = value.length == 0? value:[value stringByReplacingOccurrencesOfString:@""" withString:@"" options:NSLiteralSearch range:NSMakeRange(0, 1)];
value = value.length == 0? value:[value stringByReplacingOccurrencesOfString:@""" withString:@"" options:NSLiteralSearch range:NSMakeRange([value length]-1, 1)];
value = value.length == 0? value:[value stringByReplacingOccurrencesOfString:@"'" withString:@"" options:NSLiteralSearch range:NSMakeRange(0, 1)];
value = value.length == 0? value:[value stringByReplacingOccurrencesOfString:@"'" withString:@"" options:NSLiteralSearch range:NSMakeRange([value length]-1, 1)];
value = value.length == 0? value:[value stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];

BTW, the special tag like &nbsp； &rdquo； you havent translate them, so i wish you can handle them...LOL

BTW again, may you supply a method just give me the plaintext extra from html? thx!!!

Set frame width/height depends on htmlText

Hi

Its great one, but i'm asking how to take the CGSize for htmlText to set the frame depends on it

I used this one but it doesn't make what I need

Crashing when HTML contains "<b></b>"

It's crashing when opening and closing the b tag without content between both.

The error is in MDHTMLLabel.m, line 1194.

PS: It's not displaying the exception on Xcode's debug Area.

broken layout when inside UITableViewCell

when the view with uitableview is refreshed (e.g. when opening and closing modalVC over it), the layout of MDHTMLLabel breaks down. I mean the alignment, both horizontal and vertical.

I use:

dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.01 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{

    [cell.htmlLabel sizeToFit];
    [cell setNeedsLayout];
});

to fix this, but obviously it's not the best solution and it should not happen.

EDIT: the MDHTMLLabel is inside a UITableViewCell

Standalone MDHTMLLabel in UITableViewCell not working ?

I'm unable to get MDHTMLLabel to work in a custom UITableViewCell. I'm trying to show a plain url, without tags. The text shows up, but it is not clickable, and the delegate is not called. I've created a small test app to demonstrate this: https://dl.dropboxusercontent.com/u/41198645/TestLabel.zip.

SIGABRT Crash

While trying to set html text to label, SIGABRT crash on MDHTMLLabel.m in line number 1463.

Delegate no working in version 0.0.6?

I've just updated MDHTMLLabel via cocoapods, and it seems that didSelectLinkWithURL is no longer being called?

I've set the delegate withself.htmlMessage.delegate = self; .. I'm using MDHTMLLabel in a xib, with an IBOutlet.

great work matt

i only miss tag ;)
are you planning to add it?

Does htmlText support multiple lines like text ?

It's a great component. But I found the htmlText doesn't work the same way as the text does. It seems the multiple lines is supported but the auto shrink is not supported. Do I miss something? Thanks
