RxSwift Button repeated hit prevention

Use throttle Operator.

See here for throttle and debounce with similar functionality. RxSwift Debounce and Throttle throttle can be used to prevent repeated button presses, and debounce can be used to prevent overcalling APIs such as so-called incremental search.

Actually, it is convenient to create the following extension.

Reactive+Extenstions.swift

import RxCocoa
import RxSwift

public extension Reactive where Base: UIButton {
    var throttledTap: ControlEvent<Void> {
        return ControlEvent<Void>(events: tap
            .throttle(.milliseconds(ContinuousTap.disableTapDuration), latest: false, scheduler: MainScheduler.instance))
    }
}

public extension Reactive where Base: UIBarButtonItem {
    var throttledTap: ControlEvent<()> {
        return ControlEvent<()>(events: tap
            .throttle(.milliseconds(ContinuousTap.disableTapDuration), latest: false, scheduler: MainScheduler.instance))
    }
}

public extension Reactive where Base: UITableView {
    var throttledItemSelected: ControlEvent<IndexPath> {
        return ControlEvent<IndexPath>(events: itemSelected
            .throttle(.milliseconds(ContinuousTap.disableTapDuration), latest: false, scheduler: MainScheduler.instance) )
    }
}

public extension Reactive where Base: UICollectionView {
    var throttledItemSelected: ControlEvent<IndexPath> {
        return ControlEvent<IndexPath>(events: itemSelected
            .throttle(.milliseconds(ContinuousTap.disableTapDuration), latest: false, scheduler: MainScheduler.instance) )
    }
}

enum ContinuousTap {
    /// Disable Tap Duration in Milliseconds
    static let disableTapDuration: Int = 500
}
