iOS 10 用户通知自定义声音在后台模式



由于UILocalNotification在iOS 10中已弃用,因此我已使用UNUserNotification框架更新了本地通知流。

当应用程序位于前台并且工作正常时,该应用程序使用 AVPlayer 播放自定义声音。但在后台模式下,当触发本地通知时,将播放默认通知声音,而不是自定义声音。

但是,在iOS9中一切正常,使用"didReceiveLocalNotification"方法应用程序即使在后台模式下也可以播放自定义声音。

更新 1:

我正在设置本地通知,如下所示:

let content = UNMutableNotificationContent()
content.title = NSString.localizedUserNotificationStringForKey("reminder!", arguments: nil)
content.body = NSString.localizedUserNotificationStringForKey("Reminder body.", arguments: nil)
if let audioUrl == nil {
content.sound = UNNotificationSound.defaultSound()
} else {
let alertSound = NSURL(fileURLWithPath: self.selectedAudioFilePath)
content.sound = UNNotificationSound(named: alertSound.lastPathComponent!)
}
content.userInfo = infoDic as [NSObject : AnyObject]
content.badge = 1
let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 60, repeats: false)
let identifier = "Reminder-(date)"
let request = UNNotificationRequest(identifier: identifier, content: content, trigger: trigger)
let center = UNUserNotificationCenter.currentNotificationCenter()
center.addNotificationRequest(request, withCompletionHandler: { (error) in
if error != nil {
print("local notification created successfully.")
}
})

我已经经历了许多SO问题,但没有得到解决方案。

任何帮助将不胜感激!

在 Swift 4.2 和 Xcode 10.1 中

用于本地通知播放声音

let content = UNMutableNotificationContent()
content.title = "Notification Tutorial"
content.subtitle = "from ioscreator.com"
content.body = " Notification triggered"
//Default sound
content.sound = UNNotificationSound.default
//Play custom sound
content.sound = UNNotificationSound(named:UNNotificationSoundName(rawValue: "123.mp3"))

"123.mp3"文件需要位于捆绑包中。

发现alertSound没有正确的文件路径,因此content.sound没有设置任何内容。我将录制的文件保存在文档目录中,与模拟器相比,真实设备的文件路径检索不同。

设置放置在项目包中的声音文件就可以解决问题

content.sound = UNNotificationSound(named: "out.caf")

在推送通知包中,您需要包含要在后台播放的自定义声音。此声音也需要包含在您的应用程序中。

例如,以下是我在 PHP for iOS 中创建自定义通知包的方法。请注意,在我的通知对象中,我有一个声音对象。

array("to" => $sDeviceID,
"data" => array($sMessageType => $sMessage,
"customtitle" => $sMessageTitle,
"custombody" => $sMessage,
"customimage" => "$mIcon") ,
"notification" => array("title" => "sMessageTitle",
"text" => $sMessage,
"icon" => "$mIcon",
"sound" => "mySound.mp3"));

下面介绍如何使用具有自定义声音的UserNotifications框架创建通知。

如果notification是您UNNotificationContent,并且捆绑包中的自定义媒体文件的名称是 a.mp4,则只需使用以下代码:

notification.sound = UNNotificationSound(named: "a.mp4")

因此,您无需使用didRecieveLocalNotification.

我明白

let notificationContent = UNMutableNotificationContent()
...
notificationContent.sound = UNNotificationSound(named: "out.mp3")

工作正常,但是:

1)声音文件不应超过30秒(我认为还可以)

2)声音文件必须是Bundle.mail文件的一部分。如果它存储在其他地方,则通知在后台时将无法访问它。它在前景中工作正常。据我所知,Apple不提供访问其他文件夹的权限。

3)声音格式有限制。请参考苹果指南

4)我不确定是否可以更改Bundle.main中的声音文件 编程。例如:我编写了一个例程,该例程提取存储在苹果音乐中并由用户选择的歌曲的 30 秒......一切正常,如果信息存储在不同的目录中,但仅在前台......一旦锁定或在后台,就无法访问它。我无法更改/覆盖 Bundle.main 中的文件。如果有可能,问题就会得到解决......但我认为这将是一个安全问题。我的结论是,只要满足上述条件,警报声音和音乐就可以正常工作。

let notificationContent1 = UNMutableNotificationContent()
notificationContent1.title = "Good morning! Would you like to listen to a morning meditation to start the day fresh ? Or maybe a cool relaxing soundscape? Open the app and browse our collection which is updated daily."
notificationContent1.subtitle = ""
notificationContent1.body = ""
notificationContent1.sound = UNNotificationSound(named: UNNotificationSoundName(rawValue: "AlarmSound.wav"))
var dateComponents1 = DateComponents()
dateComponents1.hour = 08
dateComponents1.minute = 00
let trigger1 = UNCalendarNotificationTrigger(dateMatching: dateComponents1, repeats: true)
let request1 = UNNotificationRequest(
identifier: UUID().uuidString,
content: notificationContent1,
trigger: trigger1
)
let notificationContent2 = UNMutableNotificationContent()
notificationContent2.title = "Good evening! Hope you had a great day. Would you like to meditate on a particular topic ? Or just some relaxing sleep sounds ? Open the app and pick what you want so you can go to sleep relaxed."
notificationContent2.subtitle = ""
notificationContent2.body = ""
notificationContent2.sound = UNNotificationSound(named: UNNotificationSoundName(rawValue: "AlarmSound.wav"))
var dateComponents2 = DateComponents()
dateComponents2.hour = 20
dateComponents2.minute = 00
let trigger2 = UNCalendarNotificationTrigger(dateMatching: dateComponents2, repeats: true)
let request2 = UNNotificationRequest(
identifier: UUID().uuidString,
content: notificationContent2,
trigger: trigger2
)
UNUserNotificationCenter.current().delegate = self
UNUserNotificationCenter.current().add(request1, withCompletionHandler: nil)
UNUserNotificationCenter.current().add(request2, withCompletionHandler: nil)
