Earlier this year I mentioned a thread safe NSTimer replacement.
Here’s an interesting library from Cue called TheKitchenSync providing a library that makes iOS concurrency programming easier.

As the readme states:
Cue’s iOS concurrency library, TheKitchenSync, provides you with a set of advanced locks and thread-safe collections, similar to what you might find in Java.
Previously I mentioned a couple of extremely useful open source objective-c libraries from HotelTonight – a UITextField with autocompletion, and NSNotificationCenter alternative that allows you assign multiple delegates to a single source.
Here’s a collection of libraries called HTKit from the HotelTonight team team that provides a great collection of objective-c UIKit utility libraries.
These libraries include helper libraries for drawing custom UI elements, core image filter enhancements, a library for automatically caching rendered components and more.

I’ve mentioned a number of resources for creating rich text views, most recently the excellent SETextView.
Here’s an open source library from Jeff Verkoeyen called NSAttributedMarkdownParser that allows you to turn an NSString containing markdown tags into an NSAttributedString.
The library supports bold, italics, strikethrough, header and url formatting.
Here are a few images from the included catalog example project showing the markdown text rendered as Core Text:
