Sound/播放提示音, Haptics/触觉反馈, LocalNotification/本地通知的使用

1. Sound 播放提示音

1.1 音频文件: tada.mp3， badum.mp3

1.2 文件位置截图:

1.3 实现

import AVKit/// 音频管理器
class SoundManager{// 单例对象 Singletonstatic let instance = SoundManager()// 音频播放var player: AVAudioPlayer?enum SoundOption: String{case tadacase badum}func playSound(sound: SoundOption){// 获取 urlguard let url =  Bundle.main.url(forResource: sound.rawValue, withExtension: ".mp3") else { return }do{player = try AVAudioPlayer(contentsOf: url)player?.play()}catch let error{// 打印错误print("Error playing sound. \(error.localizedDescription)")}}
}/// 提示音
struct SoundsBootcamp: View {var soundManager = SoundManager()var body: some View {VStack(spacing: 40) {Button("Play sound 1") {SoundManager.instance.playSound(sound: .tada)}Button("Play sound 2") {SoundManager.instance.playSound(sound: .badum)}}}
}

2. Haptics 触觉反馈与通知

2.1 实现

/// 触觉管理器
class HapticManager{static let instance = HapticManager()// 通知func notification(type: UINotificationFeedbackGenerator.FeedbackType){let generator = UINotificationFeedbackGenerator()generator.notificationOccurred(type)}func impact(style: UIImpactFeedbackGenerator.FeedbackStyle){// 反馈生成器let generator = UIImpactFeedbackGenerator(style: style)generator.impactOccurred()}
}/// 触觉反馈与通知
struct HapticsBootcamp: View {var body: some View {VStack(spacing: 20) {Button("Success") { HapticManager.instance.notification(type: .success) }Button("Warning") { HapticManager.instance.notification(type: .warning) }Button("Error") { HapticManager.instance.notification(type: .error) }Divider()Button("Soft") { HapticManager.instance.impact(style: .soft) }Button("Light") { HapticManager.instance.impact(style: .light) }Button("Medium") { HapticManager.instance.impact(style: .medium) }Button("Rigid") { HapticManager.instance.impact(style: .rigid) }Button("Heavy") { HapticManager.instance.impact(style: .heavy) }}}
}

3. LocalNotification 本地通知

3.1 实现

import UserNotifications
import CoreLocation/// 通知管理类
class NotificationManager{// 单例static let instance = NotificationManager() // Singleton// 请求权限func requestAuthorization(){//let options: UNAuthorizationOptions = [.alert, .sound, .badge]UNUserNotificationCenter.current().requestAuthorization(options: options) { success, error inif let error = error {print("ERROR:\(error)")}else{print("Success:\(success)")}}}/// 加入一个通知func scheduleNotification(){let content = UNMutableNotificationContent()content.title = "This is my first notification!"content.subtitle = "This is was so easy!"content.sound = .defaultcontent.badge = 1// time 计时器通知let trigger = timeNotification()// calendar 日历通知// let trigger = calendarNotification()// location 位置通知//let trigger = locationNotificationTrigger()// 通知请求let request = UNNotificationRequest(identifier: UUID().uuidString,content: content,// 触发器trigger: trigger)// 当前通知中心，添加一个通知UNUserNotificationCenter.current().add(request)}/// 取消通知func cancelNotification(){UNUserNotificationCenter.current().removeAllPendingNotificationRequests()UNUserNotificationCenter.current().removeAllDeliveredNotifications()}/// 位置通知func locationNotificationTrigger()-> UNNotificationTrigger{// 经纬度let coordinates = CLLocationCoordinate2D(latitude: 40.00,longitude: 50.00)// 区域 radius: 半径，以米为单位let region = CLCircularRegion(center: coordinates,radius: 100,identifier: UUID().uuidString)region.notifyOnEntry = true; // 进入region.notifyOnExit = true;  // 退出return UNLocationNotificationTrigger(region: region, repeats: true)}/// 日历通知func calendarNotification() -> UNNotificationTrigger{// calendarvar dateComponents = DateComponents()dateComponents.hour = 16dateComponents.minute = 52dateComponents.weekday = 2 // 2: 星期一// repeats 是否重复return UNCalendarNotificationTrigger(dateMatching: dateComponents, repeats: true)}/// 计时器通知 repeats 循环/重复func timeNotification() -> UNNotificationTrigger{return UNTimeIntervalNotificationTrigger(timeInterval: 5.0, repeats: false);}
}/// 本地通知
struct LocalNotificationBootcamp: View {var body: some View {VStack(spacing: 40) {// 获取权限Button("Request permission") {NotificationManager.instance.requestAuthorization()}Button("Schedule notification") {NotificationManager.instance.scheduleNotification()}Button("Cancel notification") {NotificationManager.instance.cancelNotification()}}.onAppear {UIApplication.shared.applicationIconBadgeNumber = 0}}
}
