swift - 如何快速在两个 View 上使用滑动手势

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 View 上交换。 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);
    }
}

你正在将你的手势添加到主视图，你需要将它添加到所需的 View 中，在你的情况下它是绿色的，所以它应该是

green.addGestureRecognizer(sswipe)
