UIWebView中的后台音频播放 [英] Background audio playback in UIWebView

问题描述

我的应用程序允许用户访问通过网络播放有声读物的服务.我正在使用UIWebView来处理此问题.

My app allows users to access a service that plays audio books via the web. I am using a UIWebView to handle this.

退出应用程序或使设备进入睡眠状态后，音频将停止播放.由于我只是显示Web视图而不是直接播放音频文件，因此无法使用这些方法在后台播放音频.

When the app is exited or the device is put to sleep, the audio stops playing. Since I am just displaying the web view not playing the audio file directly, I cannot use those methods to play the audio in the background.

但是，如果您通过Safari应用程序访问相同的链接，则在手机进入睡眠状态后，音频将继续播放.如何在我的应用程序中实现相同的效果?

However, if you access the same link via the Safari app, the audio keeps playing after the phone is put to sleep. How can I achieve the same effect in my app?

推荐答案

首先，在Info.plist中为您的应用启用背景音频播放:

First, enable your app for background audio playback in your Info.plist:

<key>UIBackgroundModes</key>
<array>
    <string>audio</string>
</array>

如果您尚未这样做，请在AppDelegate或其他课程中设置您的应用以进行音频播放:

If you're not already doing so, set up your app for audio playback in your AppDelegate or other class:

import AVFoundation

// ...

do {
    try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
} catch {
    // Handle setCategory failure
    print(error)
}
