使用URL播放通知声音 [英] Play notification sound using URL

问题描述

我希望我的应用程序通过URL播放通知声音.我的自定义声音文件位于特定的工作URL上.因此，我希望我的应用使用该链接来通知用户有关通知.

I want my application to play notification sound through URL. My custom sound file lies at a particular working URL. So, I want my app to use that link to notify user about notification.

我已经尝试过AVPlayer，因为它通过URL的播放声音文件> a>

I've tried AVPlayer,since it plays sound files through URL's Check this

当我使用AppDelegate的didFinishLaunchingWithOptions和其他视图的viewDidLoad函数中的[self playselectedsong](上面链接中提供的plz检查代码)调用AVPlayer代码时，该代码正在工作.

The AVPlayer code is working when I call it using [self playselectedsong] (plz check code provided in above link) in didFinishLaunchingWithOptions of AppDelegate and viewDidLoad function of other views.

每当通知到达(didReceiveRemoteNotification)时带有音频文件URL，然后我将其添加到AVPlayer中，声音就不会播放.仅显示文本通知.

Whenever the notification arrives(didReceiveRemoteNotification) with an audio file URL,which then I add into the AVPlayer,the sound isn't playing.Only the text notification is shown.

推荐答案

1. 否，除非在Main bundle中有声音，否则无法在远程通知上播放声音. 检查Apple文档

对于iOS中的远程通知，您可以指定一种自定义声音， iOS在显示本地或远程通知时播放 应用.声音文件必须位于客户端的主捆绑包中 应用程序.

For remote notifications in iOS, you can specify a custom sound that iOS plays when it presents a local or remote notification for an application. The sound files must be in the main bundle of the client application.

1. 即使您在主捆绑包中添加了声音文件，该文件也不能超过30秒

自定义声音播放时必须在30秒以内.如果自定义声音 超过该限制，则会播放默认的系统声音.

Custom sounds must be under 30 seconds when played. If a custom sound is over that limit, the default system sound is played instead.
