Methods to allow using HTML code with CoreText

Last update: Jan 6, 2023

Overview

DTCoreText

This project aims to duplicate the methods present on Mac OSX which allow creation of NSAttributedString from HTML code on iOS.

The project covers two broad areas:

Layouting - Interfacing with CoreText, generating attributed strings from HTML code
User Interface - UI-related classes render these objects, specifically DTAttributedTextView, DTAttributedLabel and DTAttributedTextCell.

This is useful for drawing simple rich text like any HTML document without having to use a web view. For text selection and highlighting (as you might need for an Editor or Reader) there is the commercial DTRichTextEditor component which can be purchased in the Cocoanetics Parts Store.

Documentation

Documentation can be browsed online or installed in your Xcode Organizer via the Atom Feed URL.

Compatibility with CocoaPods 0.36 and frameworks

CocoaPods 0.36 is on release candidate 1. It adds support for Swift and embedded frameworks/modules. Unfortunately, DTCoreText is not compatible. Several of it's header files include headers from DTFoundation using the #import "DTClass.h" format instead of #import <DTFoundation/DTClass.h>.

Simply changing these import statements fixed modules in my project. Unfortunately, when I tried to do the same in the demo project, it didn't work because there DTFoundation is not included as a separate framework. And I'm guessing it would likely break other projects that include DTCoreText as well.

Implement Mac Rendering
I am creating an HTML String from an NSAttributedString using the Category' s html method. Since _iOS6TagsPossible is false on OSX 10.8, colors are ignored by the renderer. I've quickly patched DHTMLWriter just for testing:

if __MAC_OS_X_VERSION_MAX_ALLOWED > __MAC_10_6

_iOS6TagsPossible = YES;

endif

and it works. (NS)Colors in AttributedStrings seem to be stored under the NSForegroundColorAttributeName Key, not under kCTForegroundColorAttributeName.

Maybe this has nothing to with Mountain Lion at all but with OSX in general?

DTAttributedTextContentView sizeToFit and top margin

I am populating a DTAttributedTextContentView as follows

NSString *s = @"Vゾーンの自己表現を豊かにする、シルクタイが到着。ランダムにあしらったドット柄に色の濃淡でさらに表情を加え、定番のドット柄ネクタイをモダンな1本へと昇華しています。落ち着いた色使いで、ビジネススタイルにもマッチ。軽快なジャケット＆パンツスタイルとも好相性な1本です。";

NSAttributedString *as = [[[DTHTMLAttributedStringBuilder alloc]
    initWithHTML:[s dataUsingEncoding:NSUTF8StringEncoding]
    options:@{
        DTDefaultTextColor: [UIColor grayColor],
        DTDefaultFontSize: @(20),
        DTDefaultLineHeightMultiplier: @(2.0),
        DTDefaultFontFamily: @"Helvetica"
    }
    documentAttributes:NULL] generatedAttributedString];

[self.textView setAttributedString:as];

and then call `[self.textView sizeToFit]. Unfortunately there is way too much space at the top.

Italic style has no effect if the text is chinese

In issues 104, the chinese bold style problem has been resolved, but the Italic style of chinese has the same problem, the chinese character is same when italic style is set or not. The example html is: <--p style="font-size:20px;">东方盖饭<--/p> <--p style="font-size:20px;font-style:italic;">东方盖饭<--/p> (please remove '--' by yourself) By the way, the issues 104 is not only exists in ios 5, but ios 4.

Last list element weird padding

Hi!

Im trying to sort out a problem with lists. The last element in the list always gets a padding between the dot and the text. (See picture below)

I have found that it startet to behave like this after commit 66a90748630291841da44f929f23e1ab577499f3

I will continue to look into it. But maybe you guys know what the issue is without even looking a it :)

Thanks in advance.

Code used:

    self.textView = [[DTAttributedTextView alloc] initWithFrame:self.view.frame];

    NSDictionary *builderOptions = @{
                                     DTDefaultFontFamily: @"Helvetica"
                                     };

    NSString *html = @"<ul><li>test</li><li>test</li></ul>";

    NSData *htmlData = [html dataUsingEncoding:NSUTF8StringEncoding];

    DTHTMLAttributedStringBuilder *stringBuilder = [[DTHTMLAttributedStringBuilder alloc] initWithHTML:htmlData options:builderOptions documentAttributes:nil];

    self.textView.attributedString = [stringBuilder generatedAttributedString];

DTCoreText.h file not found
For some reason I can't compile my app anymore and I can't for the live of me figure out why - it used to work once. How is it DTCoreText can't find its own header?

I've set up a fresh submodule:

//.gitmodules [submodule "Externals/DTCoreText"] path = Externals/DTCoreText url = https://github.com/Cocoanetics/DTCoreText.git

added it as a subproject

set header paths

(I've tried many variations here, though I don't think this is the source of the error?)

gives this error during build

No known class method for selector 'initWithHTMLData:documentAttributes:'

Under iOS13 (Beta 7) TimesNewRomanPSMT will be used instead of SFUI

If you set DTDefaultFontFamily and DTDefaultFontName to iOS13 system font (family: .AppleSystemUIFont name: .SFUI-Regular) e.g. in initWithHTMLData:

NSAttributedString *attributedString = [[NSAttributedString alloc] initWithHTMLData:data options:@{ DTUseiOS6Attributes: @YES, DTDefaultFontFamily: [UIFont systemFontOfSize:[UIFont systemFontSize]].familyName, DTDefaultFontName : [UIFont systemFontOfSize:[UIFont systemFontSize]].fontName, DTDefaultFontSize : @([UIFont systemFontSize])} documentAttributes:nil];

you will get the following message:

CoreText performance note: Client called CTFontCreateWithName() using name ".SFUI-Regular" and got font with PostScript name "TimesNewRomanPSMT". For best performance, only use PostScript names when calling this API.

Set spacing between lines.

How can I achieve apple spacing between lines? Exmaple

Code I am using:

public func returnAttributedStringForHTMLString(
    fontFamily: String,
    fontName: String,
    fontSize: CGFloat,
    textColor: UIColor,
    textAlignment: CTTextAlignment
  ) -> NSMutableAttributedString {
    let encodedData = self.data(using: String.Encoding.utf8)!
    let options = [
      DTDefaultFontFamily: fontFamily,
      DTDefaultFontName: fontName,
      DTDefaultFontSize: fontSize,
      DTDefaultTextColor: textColor,
      DTDefaultTextAlignment: NSNumber(value: textAlignment.rawValue),
    ] as [String : Any]
    let builder = DTHTMLAttributedStringBuilder(html: encodedData, options: options, documentAttributes: nil)
    var returnValue: NSAttributedString?
    returnValue = builder?.generatedAttributedString()
    if returnValue != nil {
      // needed to show link highlighting
      let mutable = NSMutableAttributedString(attributedString: returnValue!)
      mutable.removeAttribute(NSAttributedString.Key.foregroundColor, range: NSMakeRange(0, mutable.length))
      return mutable
    } else {
      return NSMutableAttributedString(string: "")
    }
  }

Call site:

    Text(
      AttributedString(
        html.returnAttributedStringForHTMLString(
          fontFamily: "SF Text",
          fontName: "SF Text Regular",
          fontSize: 17,
          textColor: .label,
          textAlignment: .left
        )
      )
    )

Also I want to use default apple font that comes with the system, I am using "SF Text" for fontFamily and "SF Text Regular" for fontName, is this correct? or if there is a way to omit the parameters and automatically use the system font.

Switch to Secure Object Archiving APIs
Hello,

Created this issue to address the vulnerability with using NSCoding. The NSCoding does not verify the type of object upon deserialization and therefore is vulnerable to object substitution attacks.

To mitigate this vulnerability, Apple introduced the NSSecureCoding protocol along with the following secure methods of NSKeyedArchiver and NSKeyedUnarchiver, which are robust against this type of attack:

// Secure NSKeyedUnarchiver methods - (instancetype)initForReadingFromData:(NSData *)data error:(NSError **)error; + (id)unarchivedObjectOfClass:(Class)cls fromData:(NSData *)data error:(NSError **)error; + (id)unarchivedObjectOfClasses:(NSSet<Class> *)classes fromData:(NSData *)data error:(NSError **)error; // Secure NSKeyedArchiver methods - (instancetype)initRequiringSecureCoding:(BOOL)requiresSecureCoding; + (NSData *)archivedDataWithRootObject:(id)object requiringSecureCoding:(BOOL)requiresSecureCoding error:(NSError **)error;

Apple provides more information in the WWDC20 session, 'Securing Your App'.

The places where unsecure NSKeyedArchiver and NSKeyedUnarchiver is called :

DTAttributedTextContentView will cause Zombie layer object crash when Using DTTiledLayerWithoutFade

@odrobnik Can you do me a favour to look at this problem? This crash bothered my project for years , and I don't know how to fix it

the problem seems like when DTAttributedTextContentView 's layer is using DTTiledLayerWithoutFade, any subview added to DTAttributedTextContentView will be deallocated unexpected when the whole tableview deallocating . and this will cause some crash.

I reproduce the crash with the official example of DTCoreText, You guys can see the commit here: https://github.com/ximmyxiao/DTCoreText/commit/cbad674d10ff33fd5cce7c9d6ca5e19602a58f93

Crash calculating the bounding rect on iOS 15

Googling this error, I don't get a lot of hits, but it looks like maybe this was new API added in iOS 15? Is that something that needs to be added to DTCoreText to work properly with iOS 15?
