【问题描述】：

我正在使用 AVAudioPlayer。当我点击播放按钮时，我想播放一系列音频文件。另外，当我再次点击播放按钮时，序列播放应该暂停，然后在点击按钮时再次恢复

以下是我的代码：

NSTimeInterval totalTime, currentTime;
isPaused = NO;
isFirst = YES;

-(void)btnPlay:(id)sender
{
    if (isFirst)
    {
        NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
        NSMutableArray *audioList = [defaults objectForKey:@"AudioArray"];
        [defaults synchronize];

        NSLog(@"Audio to be Played : %@", audioList);

        for(int i = 0; i < [audioList count]; i++)
        {
            NSLog(@"Current Audio : %@", [audioList objectAtIndex:i]);

            NSString *path = [[NSBundle mainBundle] pathForResource:@"Alarm_1" ofType:@"mp3"];
            NSError *error = nil;
            NSURL *url = [NSURL fileURLWithPath:path];
            [audioPlayer setDelegate:self];
            audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];

            [audioPlayer play];
            isFirst = NO;

            totalTime = audioPlayer.duration;
            NSLog(@"Total Time : %f", totalTime);
        }
    }
    else if (!isFirst)
    {
        if (isPaused)
        {
            [audioPlayer setCurrentTime:currentTime];
            [audioPlayer play];
            isPaused = NO;
        }
        else if (!isPaused)
        {
            currentTime = audioPlayer.currentTime;

            [audioPlayer pause];
            isPaused = YES;
        }
    }
}

【问题讨论】：

您想在点击播放按钮时播放多个音频文件？我的意思是歌曲选择没有下一个或上一个按钮？
