我正在使用AVAudioRecorder和AVAudioPlayer录制和播放音频。我想通过放置标记在特定时间将音频插入AVAudioPlayer中。谁能帮我怎么做？

试试这个 :

    -(void)Play
{
    AVAudioPlayer *avPlayer = [[AVAudioPlayer alloc]initWithContentsOfURL:[NSURL fileURLWithPath:[FileDetailsRec valueForKey:@"Path"]] error:nil];
    [avPlayer setCurrentTime:5.01f];
    [avPlayer prepareToPlay];
    [avPlayer play];
    objTimer = [NSTimer  scheduledTimerWithTimeInterval:1.07f target:self selector:@selector(stop) userInfo:nil repeats:NO];
}

-(void)stop
{ 
    [objTimer invalidate];
    [avPlayer stop];
}

请检查一次。。希望对您有所帮助。
