To create folding paragraphs in TextKit 2, you can utilize the new features and APIs introduced in the WWDC 2024 sessions. Specifically, the session titled "Get started with Writing Tools" provides insights into handling text views and customizing their behavior.
Here are the steps you can follow:
-
Use Attributed Strings: TextKit 2 fully supports rich text by using attributed strings, which allows you to preserve attributes like styles, links, and attachments. This is crucial for maintaining the integrity of your text when folding and unfolding paragraphs.
-
Delegate Methods: Implement the new delegate methods provided for
UITextViewandNSTextView. These methods can help you manage the state of your text view when folding or unfolding paragraphs. For example, you can use these methods to pause syncing or avoid accidental editing during the folding process. -
Custom Behavior: Customize the behavior of your text view using the new text input traits API. You can specify whether your text view supports rich text or tables, and control the behavior of writing tools to suit your app's needs.
-
Animations: Apply animations to the text being processed to indicate the model is working. This can enhance the user experience by providing visual feedback during the folding and unfolding process.
For more detailed information, you can refer to the session Get started with Writing Tools at the 04:02 mark, which covers controlling behavior and customizing text views.
