RxSwift条件绑定

Question

I'm trying to use a UISegmentedControl with rx.selectedSegmentIndex to bind to my viewModel actions. In my viewModel I have these properties:

let showSomething1: AnyObserver<Void>
let showSomething2: AnyObserver<Void>
let showSomething3: AnyObserver<Void>

In my view controller

segmentControl.rx.selectedSegmentIndex.....

viewModel.showSomething1 if index 1
viewModel.showSomething2 if index 2
viewModel.showSomething3 if index 3

In my rx.selectedSegmentIndex i would like to bind to these but depending on the index of the selectedSegmentIndex , what is the best way to do this with RxSwift?

I also want to an animation regardless of which index is selected.

Thanks in advance

You're probably looking for something like this:

segmentedControl.rx.selectedSegmentIndex.subscribe (onNext: { index in
            doSomethingWith(index)
        })
