iOS7 Sprite Kit如何在SKSpriteNode上进行长按或其他手势？

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    [self SELEctSkill:YES];
}

在UIGestureRecognizer之前,您保留了状态变量,这些变量跟踪触及何时何地开始触摸的位置.这是一个快速解决方案,其中buttonTouched：是一种检查UITouch是否在您正在检查的按钮上的方法.

var touchStarted: NSTimeInterval?
let longTapTime: NSTimeInterval = 0.5

override func touchesBegan(touches: NSSet,withEvent event: UIEvent) {
    if let touch = touches.anyObject() as? UITouch {
        if buttonTouched(touch) {
            touchStarted = touch.timestamp
        }
    }
}

override func touchesEnded(touches: NSSet,withEvent event: UIEvent) {
    if let touch = touches.anyObject() as? UITouch {
        if buttonTouched(touch) && touchStarted != nil {
            let timeEnded = touch.timestamp
            if timeEnded - touchStarted! >= longTapTime {
                handleLongTap()
            } else {
                handleShortTap()
            }
        }
    }
    touchStarted = nil
}

override func touchesCancelled(touches: NSSet!,withEvent event: UIEvent!) {
    touchStarted = nil
}
