Way to make a UIButton continuously fire during a press-and-hold situation?

Question

You know how Mario just keeps running to the right when you press and hold the right-button on the D-Pad? In the same manner, I want my UIButton to continuously fire its act

Answer 1

And Now for Something Completely Different:
ReactiveCocoa 6.

self.button.reactive
    .controlEvents([.touchDown])
    .observeValues { button in
        SignalProducer.timer(interval: .milliseconds(500), on: QueueScheduler.main)
            .take(until: button.reactive.controlEvents([.touchDragOutside, .touchDragExit, .touchUpInside, .touchUpOutside, .touchCancel]).map { _ in return })
            .prefix(value: Date())
            .startWithValues { date in
                NSLog("\(date)")
            }
        }
