iodine

A MVVM framework based on ReactiveCocoa and built with a goal to sepparate untestable UIKit view logic from testable business logic.

How does it work?

Well it’s pretty simple:

• We create a new Model class:

  @interface MYViewModel : IOTableViewModel

• We subclass any of the IO view controllers:

  @interface MYViewController : IOTableViewController

• Then we implement the binding methods:

• (void)pre
  {
  [super pre];

  //This is where all the things prior to initializing the view go.
  //For example:
  [self rac_signalForSelector:@selector(scrollViewDidScroll:)
  fromProtocol:@protocol(UIScrollViewDelegate)];
  }

• (void)setupViews
  {
  [super setupViews];

  //Here we set up our view like we do on viewDidLoad. For example:
  [self.view addSubview:self.doneButton];
  }

• (void)post
  {
  [super post];

  //After we setup the views, we want to bind our view model against
  //them, this is where all that magic goes. For example:
  RAC(self.doneButton, userInteractionEnabled) =
  RACObserve(self.viewModel, doneEnabled);
  }

• Now just instantiate your view controller with the model and you’re done:

  MYViewModel *vm = [[MYViewModel alloc] init];
  MYViewController *vc = [[MYViewController alloc] initWithViewModel:vm];

Okay, now can I get a real example?

rprtr should be a good resource, this project was developed against it.

What about installing the framework?

You can build it as a regular framework, but I recommend using CocoaPods:

pod 'iodine'

Currently supported UIKit classes

• UIViewController (IOViewController)
• UITableViewController (IOTableViewController)
• UITableHeaderFooterView (IOTableHeaderFooterView)
• UITableViewCell (IOTableViewCell)
