I gave a presentation on blocks and Grand Central Dispatch today at MobiDevDay. You can download the slides at SlideShare.
Looking for more reading about blocks? Here are some more resources:
- Programming with C Blocks by Joachim Bengtsson
- Introducting Blocks and Grand Central Dispatch by Apple
- Blocks Programming Topics by Apple
Also, as we saw in the presentation, check out cdecl.org to cheat!
UPDATE: Looking for example code? I’ve put some of the code that went into the slides up on GitHub. It’s light, but it also includes a .PDF version of the presentation.
