如何比双击更快地识别单击？

我有一个UITableView与我添加单击的行and双击手势：

let doubleTap = UITapGestureRecognizer(target: self, action: "doubleTap:")
doubleTap.numberOfTapsRequired = 2
doubleTap.numberOfTouchesRequired = 1
        
let singleTap = UITapGestureRecognizer(target: self, action: "singleTap:")
singleTap.numberOfTapsRequired = 1
singleTap.numberOfTouchesRequired = 1
singleTap.requireGestureRecognizerToFail(doubleTap)

tableView.addGestureRecognizer(doubleTap)
tableView.addGestureRecognizer(singleTap)

有没有办法减少第一次点击和手势识别器意识到这是单击而不是双击之间的时间？

我问这个是因为当我点击一下时，新的viewController出现得很晚，给人一种应用程序滞后的感觉。

快速版本：

class UIShortTapGestureRecognizer: UITapGestureRecognizer {
    let tapMaxDelay: Double = 0.3

    override func touchesBegan(touches: NSSet!, withEvent event: UIEvent!) {
        super.touchesBegan(touches, withEvent: event)
        delay(tapMaxDelay) {
            // Enough time has passed and the gesture was not recognized -> It has failed.
            if  self.state != UIGestureRecognizerState.Ended {
                self.state = UIGestureRecognizerState.Failed
            }
        }
    }
}

With delay(delay: Double, closure:()->()):

class func delay(delay:Double, closure:()->()) {
        dispatch_after(dispatch_time( DISPATCH_TIME_NOW, Int64(delay * Double(NSEC_PER_SEC))), dispatch_get_main_queue(), closure)
    }
