iOS 系统中自带了摇一摇监测功能，这里我们只需要使用即可，当让业界也有其他方式来实现摇一摇的方法，比如监听手机晃动幅度来完成。
var player: AVAudioPlayer?
override func viewDidLoad() {
super.viewDidLoad()
self.setUI()
/**

*/
UIApplication.shared.applicationSupportsShakeToEdit = true
becomeFirstResponder()
// Do any additional setup after loading the view.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
/**
开始摇动
*/
override func motionBegan(_ motion: UIEventSubtype, with event: UIEvent?) {
print("开始摇动")
//开始动画
UIView.animateKeyframes(withDuration: 0.5, delay: 0, options: UIViewKeyframeAnimationOptions.beginFromCurrentState, animations: { () -> Void in
self.rockupImage.frame.origin.y -= 80
self.rockdownImage.frame.origin.y += 80
}, completion: nil)
/// 设置音效
let path1 = Bundle.main.path(forResource: "rock", ofType:"mp3")
let data1 = try? Data(contentsOf: URL(fileURLWithPath: path1!))
self.player = try? AVAudioPlayer(data: data1!)

self.player?.play()
//结束动画

self.rockupImage.frame.origin.y += 80
self.rockdownImage.frame.origin.y -= 80
}, completion: nil)
}
