iOS:以静音模式播放音频 [英] iOS: Playing audio in silent mode

问题描述

即使用户的静音/静音开关设置为静音/振动，让我的应用播放音频的正确"方法是什么?

What is the "correct" way to get my app to play audio even if the user's silent/mute switch is set to silent/vibrate?

一些背景: 我实际上是在调试阶段运行它的，但是当我将应用程序提交给Apple并随后从应用程序商店下载它时，音频在静音模式下被禁用了！这是我如何使其在调试阶段工作的方法:

Some background: I actually got it working in debug stage, but when I submitted my app to Apple and then later downloaded it from the app store, the audio was disabled in silent mode! Here is how I got it working in debug stage:

UInt32 sessionCategory = kAudioSessionCategory_MediaPlayback;
AudioSessionSetProperty(kAudioSessionProperty_AudioCategory,
                        sizeof(sessionCategory), &sessionCategory);

音频使用以下方式播放:

Audio was played using:

NSString *path = [[NSBundle mainBundle] pathForResource:fileName ofType:@"mp3"];  
AVAudioPlayer *theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];  
theAudio.delegate = self;
[theAudio play];

推荐答案

我认为它具有相同的作用，但是您是否尝试过像这样通过AVFoundation设置设置?

I think it does the same thing, but have you tried, setting the setting throught AVFoundation like so?

 [[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:nil];
    [[AVAudioSession sharedInstance] setActive: YES error: nil];
