iOS 11用户自定义声音通知

Question

我是一名有用的助手，可以翻译文本。

我遇到了麻烦，无法实现苹果提供的基本示例代码。该代码位于以下位置。

https://developer.apple.com/library/content/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/SchedulingandHandlingLocalNotifications.html#//apple_ref/doc/uid/TP40008194-CH5-SW3

这是我的代码，很典型。我目前遇到了一个错误：“'init(named:)'不可用”。

    let content = UNMutableNotificationContent()
    content.title = NSString.localizedUserNotificationString(forKey:"testreminder!", arguments: nil)
    content.body = NSString.localizedUserNotificationString(forKey:"Reminder body.", arguments: nil)

    content.sound = UNNotificationSound(named: "test.aiff");
    content.categoryIdentifier = "myCategory"

    let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 5, repeats: false)
    let request = UNNotificationRequest(identifier: "test.aiff", content: content, trigger: trigger)
    UNUserNotificationCenter.current().add(request, withCompletionHandler: nil)

编辑：尝试了建议后，这是代码，但它不起作用。它会提示“init(named:)不可用”

    let content = UNMutableNotificationContent()
    content.title = NSString.localizedUserNotificationString(forKey:"testreminder!", arguments: nil)
    content.body = NSString.localizedUserNotificationString(forKey:"Reminder body.", arguments: nil)

    content.sound = UNNotificationSound.init(named: "test.aiff")
    content.categoryIdentifier = "myCategory"

    let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 5, repeats: false)
    let request = UNNotificationRequest(identifier: "test.aiff", content: content, trigger: trigger)
    UNUserNotificationCenter.current().add(request, withCompletionHandler: nil)

1. 使用UNNotificationSoundName结构体来定义声音名称。

https://developer.apple.com/documentation/usernotifications/unnotificationsoundname

let soundName = UNNotificationSoundName("test.aiff")
content.sound = UNNotificationSound(named: soundName)

2. 确保在文件检查器中，声音文件的目标成员资格已被选中。文件检查器截图

我也遇到了这个问题，我将音频文件格式改为AIFF后问题得到解决。 - ZaMy
