Detect idle time and do something when timer fires (Swift)

func resetIdleTimer()

    {

        if (idleTimer == nil)

        {

           idleTimer = NSTimer.scheduledTimerWithTimeInterval(kMaxIdleTimeSeconds, target: self, selector: "idleTimerExceeded:", userInfo: nil, repeats: false)

        }

        else

        {

           if (fabs(idleTimer.fireDate.timeIntervalSinceNow) < kMaxIdleTimeSeconds-1.0)

           {

               idleTimer.fireDate = NSDate(timeIntervalSinceNow: kMaxIdleTimeSeconds)

            

           }

        }

    }

    

    func idleTimerExceeded(sender: AnyObject)

    {

        idleTimer = nil

//do something when timer fires

    }

hide/show with animation in Swift

For hiding the dock like view and show again

 func hide(sender: AnyObject)

 {

     let frame = hideshowView?.frame

     let height = frame?.size.height

     let offsetY = height!

        

     //hide after 10 seconds delay

     if frame != nil {

     UIView.animateWithDuration(0.5, delay: 10.0, options: UIViewAnimationOptions.CurveEaseIn, animations: { [weak self] () -> Void in

                

                if let weakSelf = self

                {

                    weakSelf.segmentedControl?.frame = CGRectOffset(frame!, 0, offsetY)

                    weakSelf.openBottomBarButton.hidden = false

                }

            }) { (Bool v) -> Void in

            }

      }

 }

    

 func show(sender: AnyObject)

 {

        let frame =  hideshowView?.frame

        let height = frame?.size.height

        let offsetY = -height!

        

        //show without delay

        UIView.animateWithDuration(0.5)

        {

            hideshowView?.frame = CGRectOffset(frame!, 0, offsetY)

        

        }

}

Setting ImageView corner radius iOS, Swift

To get rounded image view

imageView.layer.cornerRadius = imageView.frame.size.width / 2

imageView.layer.masksToBounds = true

Check whether array contains element in Swift

extension Array {
    func contains<T where T : Equatable>(obj: T) -> Bool {
        return self.filter({$0 as? T == obj}).count > 0
    }
}

array.contains(element)
