2014_TEST_COLLAGE.zip

This project is one of my test tasks. It's an iPhone application developed using Objective-C language in Xcode. The logic is as following: The user enters their Instagram login, and then the application downloads the most popular photos and makes a collage. Afterwards, the user can edit the collage and send it via email.

There is a full project in the attached archive. I used CocoaPods for managing third-party libraries, so please run the project by opening test-collage.xcworkspace.

You can find other code examples on https://bitbucket.org/rahmalevich
