Question

当我在模拟器上的任何地方从右向左交换时，它正在交换，但我只想在绿色视图上进行交换。我试过这个..

class ViewController: UIViewController {

@IBOutlet weak var red: UIView!
@IBOutlet weak var green: UIView!

override func viewDidLoad() {
        super.viewDidLoad()


        var sswipe = UISwipeGestureRecognizer(target: self, action:     Selector("handleSwipes:"))
        sswipe.direction = .Left
        view.addGestureRecognizer(sswipe)

        var srwipe = UISwipeGestureRecognizer(target: self, action: Selector("handleSwipes:"))
        srwipe.direction = .Right
        view.addGestureRecognizer(srwipe)

}

func handleSwipes(sender:UISwipeGestureRecognizer) {
    if(sender.direction == .Left) {
        var labelPosition = CGPointMake(self.view.frame.origin.x - 100.0, self.view.frame.origin.y)
        self.view.frame = CGRectMake(labelPosition.x , labelPosition.y , self.view.frame.size.width, self.view.frame.size.height)
    }
    if(sender.direction == .Right) {
        var labelPosition = CGPointMake(self.view.frame.origin.x + 100.0, self.view.frame.origin.y)
        self.view.frame = CGRectMake(labelPosition.x , labelPosition.y , self.view.frame.size.width, self.view.frame.size.height);
    }
}

Answer 1

您正在将手势添加到主视图中，您需要将其添加到所需的视图中，其绿色应该是

green.addGestureRecognizer(sswipe)

Answer 2

您必须先在viewdidload中声明滑动手势

 let swipeLeft = UISwipeGestureRecognizer(target: self, action: #selector(MainNotificationVC.swipeLeft))
    swipeLeft.direction = .Left
    ViewGreen.addGestureRecognizer(swipeLeft)

    let swipeRight = UISwipeGestureRecognizer(target: self, action: #selector(MainNotificationVC.swipeRight))
    swipeRight.direction = .Right
    viewRed.addGestureRecognizer(swipeRight)

比之后

 func swipeLeft() {

    //animation
    let transition: CATransition = CATransition()
    transition.type = kCATransitionReveal
    transition.duration = 0.5
    transition.subtype = kCATransitionFromLeft
    self.ViewGreen.layer.addAnimation(transition, forKey: nil)
    // add your code
}
func swipeRight() {

    let transition: CATransition = CATransition()
    transition.type = kCATransitionReveal
    transition.duration = 0.5
    transition.subtype = kCATransitionFromRight
    self.viewRed.layer.addAnimation(transition, forKey: nil)
}

如何在swift中的两个视图上使用滑动guest虚拟机
