如何在RxSwift中选择CollectionView单元格 [英] How to select CollectionView cell in RxSwift

问题描述

我需要使用RxSwift在集合视图中的特定索引处选择项目.此方法无法正常工作.

I need to select the item at specific index in collection view using RxSwift.This method is not working fine.

 collectionView.rx.modelSelected(SearchResult.self).subscribe(onNext:{ menuItem in }).addDisposableTo(disposeBag) 

有人可以帮忙吗?

推荐答案

如果要选择项目的indexPath，可以使用以下命令:

If you want the indexPath of item selected you can use the following :

collectionView
    .rx
    .itemSelected
        .subscribe(onNext:{ indexPath in
            //your code
        }).disposed(by: disposeBag)

，如果要选择模型，则:

and if you want to the model being selected :

collectionView
        .rx
        .modelSelected(SearchResult.self)
        .subscribe(onNext: { (model) in
            //Your code
        }).disposed(by: disposeBag)

并且您可以结合以上内容，以如下方式获取带有indexPath的modelSelected:

And you can combine the above, to get the modelSelected with their indexPath as follow:

  Observable
            .zip(
                collectionView
                    .rx
                    .itemSelected
                ,collectionView
                    .rx
                    .modelSelected(SearchResult.self)
            )
            .bind{ [unowned self] indexPath, model in

            }
            .disposed(by: disposeBag)
    }
