在iOS上的Objective-C中静音和取消静音 [英] Mute and UnMute in Objective-C on iOS

问题描述

大家好，我一直在尝试找到一种通过Objective-C编码进行静音和取消静音(即播放音频)的方法，而不管该应用程序是否处于静音模式(切换了物理静音)

Hi guys ive been trying to find a way to mute and unmute (that is play audio) via Objective-C in-code, regardless of whether the app is in mute mode or not (physical mute toggled)

我看到Instagram做到了，即使您的手机处于静音状态，您也可以在其中按下静音图标，它将播放视频音频.

I see Instagram does that, where you can press the mute icon even if your phone is mute, and it will play video audio.

推荐答案

您要查看使用此代码，您可以在铃声/静音"切换为静音时播放音频.

With this code you can play audio when the Ring/Silent switch to silent.

NSError *setCategoryError = nil;
BOOL success = [[AVAudioSession sharedInstance]
            setCategory: AVAudioSessionCategoryPlayback
                  error: &setCategoryError];

if (!success) { /* handle the error in setCategoryError */ }
