Two weeks ago, @thatusertwo posted
http://ioscodesamples.com/. The site contained a link to a zip file they had made, which contained a number of sample iOS projects. The samples were collected from a number of sources, mostly found here:
https://github.com/vsouza/awesome-ios and
http://cocoapods.org. @thatusertwo took down his site, most likely due to HN traffic, so I reuploaded the file to github.
The repository is useful for new iOS devs. Its a solid code reference.
Feel free to submit PR's or reorganize the readme.
