我想传递发件人redBox到函数leftSwipeFunc。我不知道如何传递一个不是的参数UISwipeGestureREcognizer。如果您知道答案，请帮助我。
let swipeLeft = UISwipeGestureRecognizer(target: self, action: Selector("leftSwipeFunc:"))
swipeLeft.direction = UISwipeGestureRecognizerDirection.Left
redBox.addGestureRecognizer(swipeLeft)
func leftSwipeFunc(gesture:UISwipeGestureRecognizer){ }
手势识别器有一个属性称为view那就是UIView他们所依附的。所以，你可以在里面使用它leftSwipeFunc获取视图：
func leftSwipeFunc(gesture: UISwipeGestureRecognizer) {
let swipedView = gesture.view
// Assuming redBox is a property of your view controller
if swipedView == redBox {
println("the redBox was swiped")
} else {
println("some other view was swiped")
}
}
