知识点总结：
1、[self.buttonPlay setBackgroundImage:[UIImage imageNamed:@"starten.png"] forState:UIControlStateNormal];
//为按钮添加图片
2、[self.slider addTarget:self action:@selector(updateValue) forControlEvents:UIControlEventValueChanged];
//slider(进度条)添加回调方法
3、self.timer = [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(timeadd) userInfo:nil repeats:YES];
//NStimer的使用
4、NSBundle *bundle = [NSBundle mainBundle];
NSString *path = [bundle pathForResource:@"tianyaguoke" ofType:@"mp3"];
NSURL * url = [NSURL fileURLWithPath: path];
self.player= [[AVAudioPlayer alloc]initWithContentsOfURL:url error:nil];
//NSBundle、NSURL 为AVAudio 添加路径
5、self.imageview = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 320, 480)];
[self.imageview setImage:[UIImage imageNamed:@"bgimg.jpg"]];
self.imageview.backgroundColor = [UIColor groupTableViewBackgroundColor];
//UIImageView 初始化
6、self.imageview.contentMode = UIViewContentModeScaleAspectFill;
self.imageview.contentMode = UIViewContentModeScaleAspectFit;
self.imageview.contentMode = UIViewContentModeScaleToFill;
//UIImageViewv 图片显示方式设定：比例充满 比例缩放 拉伸充满
7、self.player.currentTime；self.player.duration
//音乐播放器时间（当前播放的时间，时间总长）
点我下载源码 因为文件大小问题，文件中的音频被我删掉了，另附文件布局，我想大家可以看懂！
