Specifying Different Supplementary Views Per Section

[DenTelezhkin]

This depends on whether you want them to have different models or not. If data models for different sections is different, so will be the views, all you need is register all your views, and just set supplementaries on a storage.

If data types of your models is the same, then you can customize mappings using ViewModelMappingCustomizing protocol like so:

extension ViewController: ViewModelMappingCustomizing {
    func viewModelMapping(from candidates: [ViewModelMapping], for model: Any) -> ViewModelMapping? {
        // some kind of model conversion
       if model.kind == .one {
             return candidates.findOneMapping() // hypothethical method
       } else {
           // ...
       }
    }
}

It's a little cumbersome, but you'll be able to specify supplementary views for your models. I think in future releases it's possible that framework will allow overriding datasource methods to create such views without data models, but it's only theory.

Unfortunately, framework also does not have "bindings by section", not for cells, not for supplementary views, so you won't be able to specify mappings for section directly, as described in the issue. It's an interesting idea, and i heard it several times already, but did not have time to properly implement it.

Do first two solutions solve your problem?

Hey @RyanCodes!

I've released 6.0.0-beta.1 release of DTCollectionViewManager, which includes conditional mappings feature, that allows you to specify mappings per section, like so:

manager.register(SectionHeader1.self) { mapping in mapping.condition = .section(0) }
manager.register(SectionHeader2.self) { mapping in mapping.condition = .section(1) }

Hope this helps!
