I see they're also used for CoreGraphics, which was the example they showed at WWDC that put me onto the idea of using the annotations in the first place. I'll look into it, thanks for the idea!<br><div class="gmail_quote"><div dir="ltr">Saleem Abdulrasool <<a href="mailto:compnerd@compnerd.org">compnerd@compnerd.org</a>> schrieb am Mo., 18.
