ios - 在 View Controller 之间滑动手势

Question

我正在尝试在背景上创建滑动。我有三种不同颜色的背景。我做了一个按钮，当我点击我的按钮时，我的背景变成了下一个场景。我想改变这个，我想向左或向右滑动我的拇指来改变背景，而不必点击按钮。我将如何实现。

这里有更多的细节

我的 View Controller 是

import UIKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


}

快速版本:

添加手势识别器:

override func viewDidLoad() {
    super.viewDidLoad()
    let recognizer: UISwipeGestureRecognizer = UISwipeGestureRecognizer(target: self, action: "swipeLeft:")
    recognizer.direction = .Left
    self.view .addGestureRecognizer(recognizer)
}

Action 函数:

func swipeLeft(recognizer : UISwipeGestureRecognizer) {
    self.performSegueWithIdentifier("MySegue", sender: self)
}
