AVAudioPlayer在电话的音箱上播放音乐时播放音频 [英] AVAudioPlayer Play audio on music plays on the sound box of phone calls

问题描述

我有一个使用AVAudioPlayer播放.caf音频的简单代码:

I have a simple code using AVAudioPlayer, to play a .caf audio:

AppDelegate.h

AVAudioPlayer *_audioPlayer;

AppDelegate.m

- (void)playAudio{

    NSArray *dirPaths;
    NSString *docsDir;

    dirPaths = NSSearchPathForDirectoriesInDomains(
                                                   NSDocumentDirectory, NSUserDomainMask, YES);
    docsDir = dirPaths[0];

    NSString *soundFilePath = [docsDir
                               stringByAppendingPathComponent:audiosrc];

    NSURL *soundFileURL = [NSURL fileURLWithPath:soundFilePath];


    _audioPlayer = [[AVAudioPlayer alloc]
                        initWithContentsOfURL:soundFileURL
                        error:nil];

    _audioPlayer.volume = 1.0;

    [_audioPlayer play];



}

音频播放得很好，但是他没有通过设备的扬声器运行音频，而是在拨打电话的扬声器上运行音频，从而使音频变得非常低，如何解决和改变音频音箱?

The audio play very well, but he did not run the audio through the speakers of the device , but runs the audio on the speaker where the phone call is made , thus making the audio becomes very low , how to solve and change sound box ?

推荐答案

尝试将以下内容添加到playAudio方法的顶部:

Try adding the following to the top of your playAudio method:

[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryAmbient error:nil];
