iOS 的震动反馈实现记录

总共两种方式：

1. AudioToolbox 的 kSystemSoundID_Vibrate

AudioServicesPlaySystemSound(kSystemSoundID_Vibrate)

2. UIImpactFeedbackGenerator（iOS 10.0 以上）

UIImpactFeedbackGenerator(style: .medium).impactOccurred()

style 参数取值如下：

extension UIImpactFeedbackGenerator {

    public enum FeedbackStyle : Int, @unchecked Sendable {

        case light = 0
        case medium = 1
        case heavy = 2
        @available(iOS 13.0, *)
        case soft = 3
        @available(iOS 13.0, *)
        case rigid = 4
    }
}
