DTCoreText 1.6.23 | Cocoanetics

Scorching on the heels of the earlier upkeep launch, which was solely 3 Months in the past, this one was required as a result of Apple now not permits Apps to include references to UIWebView.

The primary change was that from each DTCoreText in addition to, beforehand, DTFoundation we eliminated some helper strategies for UIWebView. A view utilized by the demo to embed YouTube movies was moved to the Demo app. There was a bug in DTImageTextAttachment which triggered some photos to be sq..

There was a lacking macro which prevented compiling with a very previous deployment goal. That was additionally addressed.

There’s a recognized problem in iOS 13 once you attempt to use dynamic kind fonts when parsing HTML. For those who attempt to set a dynamic kind font’s title or household through parsing choice, you get this warning:

CoreText efficiency notice: Shopper referred to as CTFontCreateWithName() utilizing title ".SFUI-Common" and received font with PostScript title "TimesNewRomanPSMT". For greatest efficiency, solely use PostScript names when calling this API.

Effectively, the issue is that we’ve got no API that might will let you set the font occasion itself on DTCoreText, however solely to set a font or household title. That is transferred to an inside font descriptor which is handed all the way down to sub-tags, being modified as wanted. The primary drawback is that when you get the font descriptor for a dynamic font, there are different attributes set on the descriptor that are vital for correct dynamic level measurement and font face decision.

What’s wanted here’s a method to set a font itself – not simply its title – as an choice and to create an acceptable font descriptor for it that preserves the dynamic kind functionality. If anyone had been to sponsor the creation of this performance, I’d be joyful so as to add it. You possibly can electronic mail me at to inquire. In fact, pull requests are welcome as nicely.

The replace is tagged on GitHub and obtainable through CocoaPods.
