如何使用Swift使iPhone振动？

我需要使iPhone震动，但是我不知道如何在Swift中做到这一点。我知道在Objective-C中，您只需编写：

import AudioToolbox
AudioServicesPlayAlertSound(kSystemSoundID_Vibrate);

但这对我不起作用。

简短示例：

import UIKit
import AudioToolbox

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        AudioServicesPlayAlertSound(SystemSoundID(kSystemSoundID_Vibrate))            
    }
}

加载到手机上，它将振动。您可以根据需要将其放在函数或IBAction中。

代码更新：

 AudioServicesPlayAlertSoundWithCompletion(SystemSoundID(kSystemSoundID_Vibrate)) { }

正如苹果代码文档所写：

在将来的版本中将不推荐使用此功能。请改用AudioServicesPlaySystemSoundWithCompletion。

注意：如果振动不起作用。在声音和触觉设置中检查振动是否启用

在iPhone 7或7 Plus的iOS 10中，尝试：

let generator = UIImpactFeedbackGenerator(style: .heavy)
generator.impactOccurred()

其他振动类型：

import AudioToolbox

AudioServicesPlaySystemSound(1519) // Actuate "Peek" feedback (weak boom)
AudioServicesPlaySystemSound(1520) // Actuate "Pop" feedback (strong boom)
AudioServicesPlaySystemSound(1521) // Actuate "Nope" feedback (series of three weak booms)

Swift 4.2更新

只需将下面的代码插入您的项目即可。

用法

Vibration.success.vibrate()

源代码

  enum Vibration {
        case error
        case success
        case warning
        case light
        case medium
        case heavy
        @available(iOS 13.0, *)
        case soft
        @available(iOS 13.0, *)
        case rigid
        case selection
        case oldSchool

        public func vibrate() {
            switch self {
            case .error:
                UINotificationFeedbackGenerator().notificationOccurred(.error)
            case .success:
                UINotificationFeedbackGenerator().notificationOccurred(.success)
            case .warning:
                UINotificationFeedbackGenerator().notificationOccurred(.warning)
            case .light:
                UIImpactFeedbackGenerator(style: .light).impactOccurred()
            case .medium:
                UIImpactFeedbackGenerator(style: .medium).impactOccurred()
            case .heavy:
                UIImpactFeedbackGenerator(style: .heavy).impactOccurred()
            case .soft:
                if #available(iOS 13.0, *) {
                    UIImpactFeedbackGenerator(style: .soft).impactOccurred()
                }
            case .rigid:
                if #available(iOS 13.0, *) {
                    UIImpactFeedbackGenerator(style: .rigid).impactOccurred()
                }
            case .selection:
                UISelectionFeedbackGenerator().selectionChanged()
            case .oldSchool:
                AudioServicesPlaySystemSound(SystemSoundID(kSystemSoundID_Vibrate))
            }
        }
    }

对于iOS 10.0+，您可以尝试UIFeedbackGenerator

上面的简单viewController，只需在测试“单视图应用”中替换您的视图控制器

import UIKit

class ViewController: UIViewController {

    var i = 0

    override func viewDidLoad() {
        super.viewDidLoad()

        let btn = UIButton()
        self.view.addSubview(btn)
        btn.translatesAutoresizingMaskIntoConstraints = false

        btn.widthAnchor.constraint(equalToConstant: 160).isActive = true
        btn.heightAnchor.constraint(equalToConstant: 160).isActive = true
        btn.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
        btn.centerYAnchor.constraint(equalTo: view.centerYAnchor).isActive = true

        btn.setTitle("Tap me!", for: .normal)
        btn.setTitleColor(UIColor.red, for: .normal)
        btn.addTarget(self, action: #selector(tapped), for: .touchUpInside)
    }

    @objc func tapped() {
        i += 1
        print("Running \(i)")

        switch i {
        case 1:
            let generator = UINotificationFeedbackGenerator()
            generator.notificationOccurred(.error)

        case 2:
            let generator = UINotificationFeedbackGenerator()
            generator.notificationOccurred(.success)

        case 3:
            let generator = UINotificationFeedbackGenerator()
            generator.notificationOccurred(.warning)

        case 4:
            let generator = UIImpactFeedbackGenerator(style: .light)
            generator.impactOccurred()
        case 5:
            let generator = UIImpactFeedbackGenerator(style: .medium)
            generator.impactOccurred()

        case 6:
            let generator = UIImpactFeedbackGenerator(style: .heavy)
            generator.impactOccurred()

        default:
            let generator = UISelectionFeedbackGenerator()
            generator.selectionChanged()
            i = 0
        }
    }
}

我们可以在Xcode7.1中做到这一点

import UIKit
import AudioToolbox


class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        AudioServicesPlayAlertSound(kSystemSoundID_Vibrate)
    }
}

斯威夫特4.2，5.0

 if #available(iOS 10.0, *) {
      UIImpactFeedbackGenerator(style: .light).impactOccurred()
   } 

您还可以选择其他样式，例如

    style: .heavy
    style: .medium

    //Note: soft and rigid available in only iOS 13.0
    style: .soft
    style: .rigid

您可以使用AudioServices或振动手机Haptic Feedback。

// AudioServices
AudioServicesPlayAlertSound(SystemSoundID(kSystemSoundID_Vibrate))

// Haptic Feedback
UIImpactFeedbackGenerator(style: .medium).impactOccurred()

结帐我的开源框架Haptica，它同时支持Haptic Feedback，AudioServices以及独特的振动模式。适用于Swift 4.2，Xcode 10

import AudioToolbox

extension UIDevice {
    static func vibrate() {
        AudioServicesPlaySystemSound(kSystemSoundID_Vibrate)
    }
}

现在，您可以UIDevice.vibrate()根据需要致电。

可从iOS 10获得并与Haptic v2一起使用的UINotificationFeedbackGenerator，我们可以检查一下：

  let feedbackSupportLevel = UIDevice.current.value(forKey: "_feedbackSupportLevel") as? Int
        if #available(iOS 10.0, *), let feedbackSupportLevel = feedbackSupportLevel, feedbackSupportLevel > 1 {
            do { // 1
                let generator = UIImpactFeedbackGenerator(style: .medium)
                generator.impactOccurred()
            }

            do { // or 2
                let generator = UINotificationFeedbackGenerator()
                generator.notificationOccurred(.success)
            }
        } else {
            AudioServicesPlayAlertSound(SystemSoundID(kSystemSoundID_Vibrate))
        }

AudioServicesPlaySystemSound(SystemSoundID(kSystemSoundID_Vibrate))
