iOS_简单音乐播放器的实现

#import <AVFoundation/AVFoundation.h>

2、音乐播放能用到的几个简单的属性

@property (nonatomic,strong) UIProgressView *musicProgress;

@property (nonatomic,strong) NSTimer *timer;

3、加载一些基本控件

-(AVAudioPlayer *)player {
    if (!_player) {
        //获取音频文件
        NSString *music = [[NSBundle mainBundle] pathForResource:@"001" ofType:@"mp3"];
        NSURL *musicUrl = [NSURL fileURLWithPath:music];
        
        _player = [[AVAudioPlayer alloc] initWithContentsOfURL:musicUrl error:nil];
        //循环次数：1
        //numberOfLoops = -1 是无限循环
        _player.numberOfLoops = 1;
        [_player prepareToPlay];
        
    }
    return _player;
}

//创建UI控件
-(void)creatrUI {
    //创建button
    NSArray *array = [NSArray arrayWithObjects:@"开始
