How to properly select content os a model based on a filter selected by a UISegmentedControl? about reactiveviewmodel HOT 3 CLOSED

There are a couple of different approaches you can take. First, the view model shouldn't be the data source of the table view, but rather the view controller should ask the view model for things like number of rows, etc. I would have a selection property on the view model that is bound to the selected index of the segmented control using ReactiveCocoa. Then whenever that selection changes, reload the table view. Finally, depending on the selection property, the view model will return different data.

Hope that helps – let me know if you'd like any clarification. Also, this is just how I would approach this problem. Feel free to experiment!

So the view controller should still be the data source (as a delegate, being a UITableViewController subclass (not my case) or via -[RACSignal rac_signalForSelector:fromProtocol:]) of the table view, instead of turning the view model as the data source? I thought letting the view model be the data source would be a better approach, but looking at your FunctionalReactivePixels, the galley, for example, is a UICollectionViewController subclass.

I'll experiment and return this after that. Thank you

Generally, view models should not interact with the UI framework at all. Becoming a UITableViewDataSource requires knowledge of UITableViewCell, which isn't appropriate for the view model.
