Things most people use:
- afmotion (if you need networking )
- motion-hockeyapp (or Testflight)
From there, it depends. ProMotion is very popular, but some people want to be closer to the metal. My gem RMQ is popular, some people use it for everything (like we do) or just parts of it. Many people use ProMotion and RMQ together.
A lot of people use Sugarcube. It pollutes a lot of classes, so if you like that it's awesome with tons of sugar, if you don't it probably isn't for you.
Teacup is basically deprecated at this point. Use MotionKit or RMQ instead for stylesheets. I use RMQ of course, but MotionKit is really nice and I'd be totally happy using it as well. RMQ has grids, MotionKit has a very nice syntax and is less verbose. RMQ's stylesheets are more integrated with RMQ. MotionKit works in OS X and Android soon (RMQ is iOS only, although it should be portable to Android).
If you use Core Data, I recommend CDQ, there really isn't any competition to it (my company makes CDQ, full disclosure).
Normally people use a variety of CocoaPods, here a few common ones:
- AFNetworking (this is the standard of course, and AFMotion uses this)
I'd guess these are some common configurations:
- Bubblewrap, RMQ
- Bubblewrap, Sugarcube, MotionKit
- Bubblewrap, ProMotion, Sugarcube, MotionKit
- Bubblewrap, ProMotion, RMQ
- Bubblewrap, ProMotion, Sugarcube, MotionKit, RMQ (used for events, animations, etc, not stylesheets)
