I’ve just added a few very useful code snippets/gists for iOS devs to Github. Check them out: gist.github.com/mwaterfall

MWPhotoBrowser is an implementation of a photo viewer that I wrote for Momento allowing the user to view one or more images in a similar way to the native Photos app. It can display one or more images by providing either UIImage objects, file paths to images on the device, or URLs to images online. The photo browser handles the downloading and caching of photos from the web seamlessly. Photos can be zoomed and panned, and optional (customisable) captions can be displayed.

A must read article for any iOS developer, it provides great information on the various versions of ARM and explains how and why you should enable Thumb when targeting ARMv7.

A fascinating article by Mike Ash explaining in great detail the concepts of characters and encodings. He discusses ASCII, ASCII compatibility, Latin-1 (ISO-8859-1, Windows-1252, ISO 8859-1), Unicode and UTF-8/16/32. There’s also useful information on NSString’s and how best to decode NSData bytes when the correct encoding isn’t known.
