Tickle / Rubover自定义手势识别Swift

Question

我正在尝试在Xcode（Swift）中的图像上设置自定义手势。 手势是关于摩擦图像或连续挠痒，并在手指移动时以时间间隔触发我的功能。

我会在这里感谢一些帮助。

非常感谢。

//这是我的想法，未经过测试

var time = 0.0
var timeInterval = 1.0
var everyTime = 0.1
func addPan() {
    let imageView = UIImageView()
    //imageView.frame = xxxx
    let pan = UIPanGestureRecognizer(target: self, action: #selector(panGesture(gesture:)))
    imageView.isUserInteractionEnabled = true
    imageView.addGestureRecognizer(pan)
}
func panGesture(gesture : UIPanGestureRecognizer) {
    if gesture.state == .changed, time >= timeInterval {
        print("time interval is \(everyTime) every is \(everyTime)")
    }
}
func addtimer() {
    let timer = Timer.scheduledTimer(timeInterval: timeInterval, target: self, selector: #selector(timerAction), userInfo: nil, repeats: true)
    RunLoop.current.add(timer, forMode: RunLoopMode.commonModes)
}
func timerAction() {
    time += timeInterval
    if time >= timeInterval {
        time = 0.0
    }
}
