简单播放音频

• 一个的播放音频小功能，以前没有做过音频，于是在网上找了很多demo，但是没有想要的，然后自己去研究一个官网文档，自己也随意写了一个demo，本地播放与网络播放就是url上的差别，其他基本上一致
  

//本地播放
#import "LocationViewController.h"
#import <AVFoundation/AVFoundation.h>
 
@interface LocationViewController ()
 
/* 播放器 */
@property (nonatomic, strong) AVPlayer *player;
 
@end
 
@implementation LocationViewController
 
- (void)viewDidLoad {
    [super viewDidLoad];
    self.view.backgroundColor = [UIColor whiteColor];
}
 
#pragma mark - 懒加载
- (AVPlayer *)player
{
    if (!_player) {
        //1.创建单乐资源
        NSURL *url = [[NSBundle mainBundle] URLForResource:@"14945107.mp3" withExtension:nil];
        
        AVPlayerItem *playerItem = [AVPlayerItem playerItemWithURL:url];
        
        //创建播放器
        //        _player = [AVPlayer playerWithURL:url]; //这个不能改变音乐的动态
        _player = [AVPlayer playerWithPlayerItem:playerItem];//可以改变音乐的动态
        
    }
    return _player;
}
 
- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event
{
    [self.player play];
    
//    //切换另外一首音乐
//    AVPlayerItem *nextPlayItem = [AVPlayerItem playerItemWithURL:nil];
//    [self.player replaceCurrentItemWithPlayerItem:nextPlayItem];
}

//网络播放
 
#import "NetworkMusicViewController.h"
#import <AVFoundation/AVFoundation.h>
 
@interface NetworkMusicViewController ()
 
/* 播放器 */
@property (nonatomic, strong) AVPlayer *player;
 
 
@end
 
@implementation NetworkMusicViewController
 
- (void)viewDidLoad {
    [super viewDidLoad];
    self.view.backgroundColor = [UIColor whiteColor];
}
 
- (AVPlayer *)player
{
    if (!_player) {
        //1.创建音乐资源
        NSURL *url = [NSURL URLWithString:@"http://wvoice.spriteapp.cn/voice/2015/0824/55dafc15020d9.mp3"];
        
        AVPlayerItem *playerItem = [AVPlayerItem playerItemWithURL:url];
        
        //2.创建播放器
        _player = [AVPlayer playerWithPlayerItem:playerItem];
    }
    return _player;
}
 
- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event
{
    [self.player play];
}
