简单播放音频

  最近做一个项目，有一个小功能是播放音频，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];

}
