Since I've posted the JSTokenField project, I might as well post about my other open source pride and joy, JSCoreTextHyperlinkView.
The project includes an example of how to use the core text view. It's pretty simple - create the view with a 0 height frame, set the attributes, set its text, and then ask it for it's size so that the height is just correct. It will calculate based on the constraining width, and any padding that you set.
There is also a Twitter specific subclass that enables @usernames and #hashtags to be linkified.
To use CoreTextHyperlinkView in your apps:
- Copy The contents of the AutoHyperlinks folder, and the files
.mand, if you want Twitter username and hashtag support, copy
- Link against the CoreText framework.
