UIACtivity ViewController 활용

UIButton으로 호출

ButtonShare.addTarget(self, action: "share_action:", forControlEvents: .TouchUpInside)

U I ongPress Gestrure Recognizer로 호출

// 長押し
var myLongPressGesture = UILongPressGestureRecognizer(target: self, action: "lognPress:")

// 長押し - 2.0秒
myLongPressGesture.minimumPressDuration = 2.0
// 長押し - 許容範囲15px
myLongPressGesture.allowableMovement = 150

// 画像に長押しがあったときの対応
SampleImage.userInteractionEnabled = true
SampleImage.addGestureRecognizer(myLongPressGesture)
