1. MTV Uutiset Three tech things I liked Markus Kauppila @markuskauppila
2. Brings MTV’s news content to mobile platforms 3 native apps (iOS, Android, Windows Phone) + backend for mobile-specific logic Started out as a greenfield project
3. Common design on all three platforms With some minor platform specific tweaks Some bold choices such as hero images and page-based scrolling Quite heavy on using custom views
4. MODEL VIEW VIEWMODEL
5. Architectural pattern that’s gaining some traction Helps to separate UI from application logic Also increases possibility for unit testable code Needs a way to do data bindings => Reactive Cocoa || KVOController
6. MVC - MVVM MVVM on iOS MVVM M C V M VM V M VM V C MVC Visualization by Bob Spryn !
7. Good Links Reactive Cocoa and MVVM – An Introduction by Bob Spryn Introduction to MVVM by Ash Furrow Basic MVVM with ReactiveCocoa On MVVM, and Architecture Questions
8. AUTO LAYOUT + UI WITHOUT INTERFACE BUILDER
9. Entire UI created code No need to twiddle with Interface Builder Keeps all the UI code at one place Easy to use Masonry as DSL for Auto Layout => IMHO clean and simple approach
10. Most views in MTV Uutiset app are quite similar Dynamically created based on content Basically all just stacks of views Stacks are really easy with Auto Layout Just connect bottom and top constraints
11. Some views such as embedded html views and ad views need to change their height after the layout Auto Layout can handle it automatically Relies on the implementation of intrisicContentSize:! ! So much simpler than calculating proper frames for all the views manually
12. Still debugging Auto Layout constrains is PITA Naming the constraints helps Reveal 1.5 can visualize the constraints And Auto Layout has impact on performance, especially if you’re creating views on the fly
13. Good Links Auto Layout Practices for Minimum Pain Auto Layout Performance on iOS Advanced Auto Layout Toolbox
14. HOCKEYAPP + COCOALUMBERJACK ♥️
15. HockeyApp simple way to distribute betas Provides symbolicated stack traces in crash reports CocoaLumberjack – really neat logging framework Naturally supports logging to a file HockeyApp can attach the log file to crash reports Log file provides context for the stack traces
