Hello Marcio,
thanks for your contribution. What exactly is the contribution of the pull request compared to current master version please?

From what I understand from commits and testing this code:

• It is creating new project for examples and just copying source codes from already existing example app
• Making the original example project not work, the project cannot even be opened
• Making a lot of unnecessary changes (git changes) in project files

Only added value seems to be added support for Cocoa pods to example project, but I believe its not worth the troubles in this case

Hello Lukas,

you are right. This PR addresses only a better support to cocoapods. My thought was:
• before do any changes maybe it could be worth to fix the current workspace (since when you download it it does not match the usual cocoapods standards)
• the original project still works, you need to run pod install (see http://guides.cocoapods.org/making/using-pod-lib-create). We can include Podfile.lock and Pods if you want to save the user from doing this

Last bit, only to give you a better picture, about other changes I made so far and I have not included in the PR:
• return a reference to the AFHTTPRequestOperation (then we can cancel them, for instance)
• extension that returns "open now" and "opening hours" from a detail response

Many thanks for your time and thank you for your very nice library
