ios - 当应用程序加入agora.io channel 时，AVAudioPlayer自动停止

当用户在我的应用程序中单击“ call ”按钮/ joinChanne(Agora)时，我正在添加声音。

    [self.agoraKit joinChannelByToken:self.userManager.agoraToken channelId:self.userManager.channelName info:nil uid:[self.userManager.UID integerValue] joinSuccess:^(NSString *channel, NSUInteger uid, NSInteger elapsed) {
        NSString *path = [[NSBundle mainBundle] pathForResource:@"ringing-sound-jalebi" ofType:@"mp3"];
        NSURL *soundFileURL = [NSURL fileURLWithPath:path];
        self.audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFileURL error:nil];
        self.audioPlayer.delegate = self;
       [self.audioPlayer play];
     }];

但是我收到“AVAudioSession.mm:997:-[AVAudioSession setActive:withOptions:error:]:停用正在运行I / O的音频会话。在停用音频会话之前，应停止或暂停所有I / O”。 。有人可以帮我解决这个问题吗

最佳答案

加入通话时，Agora SDK似乎会自动停用所有现有的AVAudioSession，以确保您能听到与之通话的人的声音。我建议改为通过Agora的sound mixing API播放声音。

// Plays an audio effect file.
int soundId = 1; // The sound ID of the audio effect file to be played.
NSString *path = [[NSBundle mainBundle] pathForResource:@"ringing-sound-jalebi" ofType:@"mp3"]; // The file path of the audio effect file.
int loopCount = 1; // The number of playback loops. -1 means an infinite loop.
double pitch = 1; // Sets the pitch of the audio effect.
double pan = 1; // Sets the spatial position of the audio effect. 0 means the effect shows ahead.
double gain = 100; // Sets the volume. The value ranges between 0 and 100. 100 is the original volume.
BOOL publish = true; // Sets whether to publish the audio effect.
[self.agoraKit playEffect:soundId filePath:path loopCount:loopCount pitch:pitch pan:pan gain:gain publish:publish];
