**1.UITapGestureRecognizer click/double click gesture **

var tapGesture = UITapGestureRecognizer(target: self, action: "handleTapGesture:") 
// Set the number of gesture clicks , Double-click: point 2 Under the  
tapGesture.numberOfTapsRequired = 2 
self.view.addGestureRecognizer(tapGesture)

**2.UIPinchGestureRecognizer pinch (zoom in/out) gesture **

var pinchGesture = UIPinchGestureRecognizer(target: self, action: "handlePinchGesture:") 
self.view.addGestureRecognizer(pinchGesture)

**3.UIRotationGestureRecognizer rotating gesture **

var rotateGesture = UIRotationGestureRecognizer(target: self, action: "handleRotateGesture:") 
 self.view.addGestureRecognizer(rotateGesture) 

**4. UIPanGestureRecognizer drag gesture **

 var panGesture = UIPanGestureRecognizer(target: self, action: "handlePanGesture:") 
 self.view.addGestureRecognizer(panGesture) 

**5. UISwipeGestureRecognizer swipes **

var swipeGesture = UISwipeGestureRecognizer(target: self, action: "handleSwipeGesture:") 
swipeGesture.direction = UISwipeGestureRecognizerDirection.Left // No, it's right  
self.view.addGestureRecognizer(swipeGesture)

**6. UILongPressGestureRecognizer long gesture **

   var longpressGesutre = UILongPressGestureRecognizer(target: self, action: "handleLongpressGesture:") 
    // According to time long  
    // longpressGesutre.minimumPressDuration
    // Required number of touches
    /// longpressGesutre.numberOfTouchesRequired 
    self.view.addGestureRecognizer(longpressGesutre) 
UIGestureRecognizerState  Enumeration is defined as follows
enum UIGestureRecognizerState : Int {
    case Possible // the recognizer has not yet recognized its gesture, but may be evaluating touch events. this is the default state
    case Began // the recognizer has received touches recognized as the gesture. the action method will be called at the next turn of the run loop
    case Changed // the recognizer has received touches recognized as a change to the gesture. the action method will be called at the next turn of the run loop
    case Ended // the recognizer has received touches recognized as the end of the gesture. the action method will be called at the next turn of the run loop and the recognizer will be reset to UIGestureRecognizerStatePossible
    case Cancelled // the recognizer has received touches resulting in the cancellation of the gesture. the action method will be called at the next turn of the run loop. the recognizer will be reset to UIGestureRecognizerStatePossible
    case Failed // the recognizer has received a touch sequence that can not be recognized as the gesture. the action method will not be called and the recognizer will be reset to UIGestureRecognizerStatePossible
}
