如何從iPod應用程序中的iPod庫播放歌曲？

Question

我對iPhone和ios開發中的音頻播放非常新穎。我想在我的應用程序中播放iPod庫中的歌曲。我在Google中搜索了我的最佳水平。但是，我得到了使用iPod庫的答案，但是，我不知道要從iPod庫播放選定的歌曲。這是我的代碼中使用的應用程序，

MPMediaPickerController *picker = [[MPMediaPickerController alloc] initWithMediaTypes: MPMediaTypeMusic]; 

     picker.delegate = self; 
     picker.allowsPickingMultipleItems = NO;  
     picker.prompt = NSLocalizedString (@"Select songs to play", "Prompt in media item picker"); 
     [self presentModalViewController:picker animated:YES]; 
     [picker release]; 

     - (void) mediaPicker: (MPMediaPickerController *) mediaPicker didPickMediaItems: (MPMediaItemCollection *) mediaItemCollection 
    { 
     [self dismissModalViewControllerAnimated: YES]; 
     NSLog(@"MediaItemCollection : %@", mediaItemCollection); 

     MPMediaQuery *everything = [[MPMediaQuery alloc] init]; 
     NSLog(@"Logging items from a generic query..."); 
     NSArray *itemsFromGenericQuery = [everything items]; 
     for (MPMediaItem *song in itemsFromGenericQuery) 
     { 
      NSString *songTitle = [song valueForProperty: MPMediaItemPropertyTitle]; 
      NSLog (@"%@", songTitle); // Here i retrieved all song titles. 
     } 
} 

任何人都可以請建議我播放從iPod庫的歌曲？

- (void)mediaPicker:(MPMediaPickerController *)mediaPicker didPickMediaItems:(MPMediaItemCollection *)mediaItemCollection 
{ 
    MPMusicPlayerController *player = [MPMusicPlayerController iPodMusicPlayer]; 
    [player setQueueWithItemCollection:mediaItemCollection]; 
    [player play]; 
}
