Ios 如何通过将音频成功保存到文件来知道AVAudioRecorder何时停止？

通过将某些内容记录到指定的文件中

[[ AVAudioRecorder alloc] initWithURL:_fileURL settings:settings error:&_error];

一旦停止录音机并成功保存文件，需要立即播放录制的文件

问题是如何确定何时可以读取文件并播放它。可以使用哪个代理api？

您是否尝试过使用

- (void) audioRecorderDidFinishRecording:(AVAudioRecorder *)recorder successfully:(BOOL)flag 
{
    // Play the audio
}

---

设置

AVAudioRecorder

实例的委托

AVAudioRecorder* test = [[AVAudioRecorder alloc] initWithURL:_fileURL settings:settings error:&_error];

然后实施

- (void) audioRecorderDidFinishRecording:(AVAudioRecorder *)recorder successfully:(BOOL)flag 
{
    // play the recorded audio here
    if (flag)
    {
        NSError* error;
        AVAudioPlayer* player = [[[AVAudioPlayer alloc] initWithContentsOfURL:[recorder url] error:&error] autorelease];
        if (!error)
        {
            [player play];
        }
    }
}
