一.通过弹出控制器，获取本地音乐列表，然后播放。该方法类似于UIImagePickerController。
- 导入MediaPlayer.framework框架。
1 -(void)musicInit{
2 //创建播放器控制器
3 MPMediaPickerController *mpc = [[MPMediaPickerController alloc] initWithMediaTypes:MPMediaTypeAnyAudio];
4 //设置代理
5 mpc.delegate = self;
6 [self presentViewController:mpc animated:YES completion:nil];
7 }
- 实现代理<MPMediaPickerControllerDelegate>，及其两个方法：
1 #pragma mark - Delegate
2 //选中后调用
3 - (void)mediaPicker:(MPMediaPickerController *)mediaPicker didPickMediaItems:(MPMediaItemCollection *)mediaItemCollection{
4 NSArray *items = mediaItemCollection.items;
5 MPMediaItem *item = [items objectAtIndex:0];
6 NSString *name = [item valueForProperty:MPMediaItemPropertyTitle];
7 NSLog(@"name= %@",name);
8 MPMediaItemArtwork *artwork = [item valueForProperty:MPMediaItemPropertyArtwork];
9 UIImage *image = [artwork imageWithSize:CGSizeMake(100, 100)];//获取图片
10 // MPMediaItemPropertyPlaybackDuration 总时间的属性名称
11
12 // MPMusicPlayerController *mpc = [MPMusicPlayerController iPodMusicPlayer]; //调用ipod播放器
13 MPMusicPlayerController *mpc = [MPMusicPlayerController applicationMusicPlayer];
14 //设置播放集合
15 [mpc setQueueWithItemCollection:mediaItemCollection];
16 [mpc play];
17
18 [self dismissViewControllerAnimated:YES completion:nil];
19 }
20 //点击取消时回调
21 - (void)mediaPickerDidCancel:(MPMediaPickerController *)mediaPicker{
22 [self dismissViewControllerAnimated:YES completion:nil];
23 }
二. 仅获取本地音乐的列表
- 导入MediaPlayer.framework框架。
1 #import <UIKit/UIKit.h>
2 #import <MediaPlayer/MediaPlayer.h>
3
4 @interface MusicListTableViewController : UITableViewController
5
6 @property (nonatomic,retain) NSMutableArray *items; //存放本地歌曲
7 @property (nonatomic,retain) MPMusicPlayerController *mpc; //播放器对象
8
9 @end
1 - (void)viewDidLoad
2 {
3 [super viewDidLoad];
4
5 self.items = [NSMutableArray array];
6 //监听歌曲播放完成的通知
7 [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(reload) name:MPMusicPlayerControllerNowPlayingItemDidChangeNotification object:nil];
8 [self initMusicItems];
9 }
10
11 - (void)didReceiveMemoryWarning
12 {
13 [super didReceiveMemoryWarning];
14 // Dispose of any resources that can be recreated.
15 }
16
17 #pragma mark - Private Method
18 -(void)initMusicItems{
19 //获得query，用于请求本地歌曲集合
20 MPMediaQuery *query = [MPMediaQuery songsQuery];
21 //循环获取得到query获得的集合
22 for (MPMediaItemCollection *conllection in query.collections) {
23 //MPMediaItem为歌曲项，包含歌曲信息
24 for (MPMediaItem *item in conllection.items) {
25 [self.items addObject:item];
26 }
27 }
28 //通过歌曲items数组创建一个collection
29 MPMediaItemCollection *mic = [[MPMediaItemCollection alloc] initWithItems:self.items];
30 //获得应用播放器
31 self.mpc = [MPMusicPlayerController applicationMusicPlayer];
32 //开启播放通知，不开启，不会发送歌曲完成，音量改变的通知
33 [self.mpc beginGeneratingPlaybackNotifications];
34 //设置播放的集合
35 [self.mpc setQueueWithItemCollection:mic];
36 }
37
38 -(void)reload{
39 //音乐播放完成刷新table
40 [self.tableView reloadData];
41 }
42
43 #pragma mark - Table view data source
44
45
46 - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
47 {
48 return self.items.count;
49 }
50
51 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
52 {
53 static NSString *CellIdentifier = @"MusicCellIdentifier";
54 UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
55
56
57 MPMediaItem *item = self.items[indexPath.row];
58 //获得专辑对象
59 MPMediaItemArtwork *artwork = [item valueForProperty:MPMediaItemPropertyArtwork];
60 //专辑封面
61 UIImage *img = [artwork imageWithSize:CGSizeMake(100, 100)];
62 if (!img) {
63 img = [UIImage imageNamed:@"musicImage.png"];
64 }
65 cell.imageView.image = img;
66 cell.textLabel.text = [item valueForProperty:MPMediaItemPropertyTitle]; //歌曲名称
67 cell.detailTextLabel.text = [item valueForProperty:MPMediaItemPropertyArtist]; //歌手名称
68 if (self.mpc.nowPlayingItem == self.items[indexPath.row]) {
69 cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
70 }else{
71 cell.accessoryType = UITableViewCellAccessoryNone;
72 }
73
74
75 return cell;
76 }
77
78
79
80 #pragma mark - Table view delegate
81
82 - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
83 {
84 [self.tableView deselectRowAtIndexPath:indexPath animated:NO];
85 //设置播放选中的歌曲
86 [self.mpc setNowPlayingItem:self.items[indexPath.row]];
87 [self.mpc play];
88
89 [self.tableView reloadData];
90 }
