Update UIButton title and select the action accordingly using RxSwift

Question

I am new to RxSwift, so I wonder If it is possible to update UIButton title and select the action accordingly using RxSwift.

Say, I have a custom UIButton inside my UITableViewCell which I intend it to trigger a set of custom actions when the user taps, (e.g: like or dislike image or post or whatever...)

So, is that possible, for instance, to set the custom title, image, and action of a UIButton accordingly, and update the UI..

For more explanation of the point, say, I have two actions user can interact with the button: func imageDisliked() and imageLiked(), So when the Image is disliked, I want the button to set its title "imageDisliked" and its icon "dislikeIcon" and vice versa..

is that possible with RxSwift?

Answer 1

Rx is all about cause and effect. Some things cause events to happen and some things listen for an event and do something as a result.

A button tap myButton.rx.tap emits events, it's a cause. A button's title myButton.rx.title(for: .normal) is an effect. So is its image myButton.rx.image(for: .normal).

As for your imageLiked() and imageDisliked(), at this point they sound like effects, but you haven't outlined the causes properly yet.

So the answer to your question is, yes it is possible to update a UIButton. You just need to outline what effects you want, and for each effect you need to outline the cause or causes.
