ios webview控件的html中的音频不起作用 [英] Audio in html of ios webview control doesnot work

问题描述

我在 html 中包含了一个音频标签，我正在 UIWebview 控件中加载 html.当我单击播放按钮时播放音频.但是当我将手机置于静音模式时，它会停止播放，而是静音.

I have included a audio tag in html and i am loading the html inside the UIWebview control. The audio plays when i click on the play button. But when i put the phone in silent mode it stops playing and instead goes on mute.

我希望即使手机处于静音模式也能播放音频.

I want the audio to play even when the phone is in silent mode.

有人可以帮我解决这个问题吗?

Can anyone please help me with this?

推荐答案

请添加以下代码:-

NSError *setCategoryErr = nil;
NSError *activationErr  = nil;
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:&setCategoryErr];
[[AVAudioSession sharedInstance] setActive:YES error:&activationErr];

如果即使应用程序处于后台模式也想运行音频，请在 application:didFinishLaunchingWithOpitons 中使用以下代码:

IF you want to run audio even if app is in background mode than use below code in application:didFinishLaunchingWithOpitons:

[[AVAudioSession sharedInstance] setDelegate:self];
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:nil];
[[AVAudioSession sharedInstance] setActive:YES error:nil];
[[UIApplication sharedApplication] beginReceivingRemoteControlEvents];

applicationDidEnterBackground:

[[UIApplication sharedApplication] beginBackgroundTaskWithExpirationHandler:NULL];
[[UIApplication sharedApplication] beginReceivingRemoteControlEvents];

希望，现在这会对你有所帮助.

Hope, now this will help you.
