音樂播放器

這裡做一個簡單的音樂播放器，資料是載入的本地的 實現了簡單的點選播放的功能 

使用了#import <AVFoundation/AVFoundation.h> 框架  之後會持續的完善更新音樂播放器

核心程式碼：

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    //播放音樂
    
    QHMusic *music = self.musicArray[indexPath.row];
    
    //建立播放器
    
    NSURL *url = [[NSBundle mainBundle]URLForResource:music.filename withExtension:nil];
    
    //注意這裡必須使用全域性變數
    AVAudioPlayer *audioPlayer = [[AVAudioPlayer alloc]initWithContentsOfURL:url error:nil];
    
    //緩衝(以便後面播放比較流暢)
    
    [audioPlayer prepareToPlay];
    
    //開始播放
    [audioPlayer play];
    
    self.audioPlayer = audioPlayer;
    
    
}
