RxReusable

RxReusable provides some APIs for managing life cycle of reusable cells and views.

APIs

⚠️ In order to use these features properly, you should set delegate by using rx.setDelegate(_:).

UITableView

- tableView.delegate = self
+ tableView.rx.setDelegate(self)

UICollectionView

- collectionView.delegate = self
+ collectionView.rx.setDelegate(self)

• var disposeBag: DisposeBag

  UITableViewCell and UICollectionView now has their own disposeBag as a property. The dispose bag is automatically disposed on prepareForReuse().

  observable
    .subscribe()
    .addDisposableTo(cell.disposeBag)

• var isDisplaying: ControlEvent<Bool>

  The reactive wrapper for the cell or view is currently displaying or not. This will emit true when the tableView(_:willDisplay:forRowAt:) or collectionView(_:willDisplay:forItemAt:) is executed and false when the tableView(_:didEndDisplaying:forRowAt:) or collectionView(_:didEndDisplaying:forItemAt:) is executed.

  cell.rx.isDisplaying
    .subscribe(onNext: { isDisplaying in
      print("Cell became \(isDisplaying ? "visible" : "invisible")")
    })

• func whileDisplaying(_:_:)

  This operator makes the observable emit items only when the cell or view is currently displaying or not.

  observable.whileDisplaying(cell, true)  // emit items when the cell is visible
  observable.whileDisplaying(cell, false) // emit items when the cell is not visible
