iOS 录音后播放声音变小解决办法

//开始录音

- (void)startRecording

{

AVAudioSession * session = [AVAudioSession sharedInstance];

NSError * sessionError;

[session setCategory:AVAudioSessionCategoryPlayAndRecord error:&sessionError];

if(session == nil)

NSLog(@"Error creating session: %@", [sessionError description]);

else

[session setActive:YES error:nil];

}

//结束录音

- (void)stopRecording

{

//&& self.audioRecorder.isRecording

if (self.audioRecorder && self.recordingState == ECDialogLineRecordingStateRecording)

{

AVAudioSession *session = [AVAudioSession sharedInstance];

[session setCategory:AVAudioSessionCategoryPlayback error:nil];  //此处需要恢复设置回放标志，否则会导致其它播放声音也会变小

self.currentAudioTime = self.audioRecorder.currentTime;

[[self audioRecorder] stop];

}

}
