问题描述

在我的iPhone应用程序中我能够浏览iphone音乐库

但是下次运行app时我没有获得我之前导入的媒体文件名

In MY iPhone App I am able to browse iphone Music Library even I am importing media file name to my app music file list but while running app next time i am not getting media file name which I imported previously

在我的应用程序中我正在从我的APP文件夹中的一个文件夹MusicSampler导入歌曲在按钮上单击我打开iPod音乐库和选择歌曲（使用mediaPicker）添加到我的歌曲列表中，现在下次当我打开我的应用程序时，它会加载musicSampler文件夹中的所有歌曲，但这次是以前从iPod-添加的新歌曲图书馆没有显示

In My App i am importing songs from one folder "MusicSampler" which is in my APP Folder now On buttonclick I am opening iPod music Library and selecting song (Using mediaPicker) which is added to my song list at buttom, now next time when i am opening my App it loads the all songs from "musicSampler" folder but this time the new added songs previously from iPod-Library are not showing

我应该怎样做才能将导入的歌曲从iPod音乐库保存到我的iphone应用程序（通过将音乐文件添加到我的MusicSampler或其他内容）

what I should do to save imported song from iPod music library to my iphone app( either by adding music file to my "MusicSampler" or something else)

请帮助和建议

推荐答案

OPEN音乐电话库

 MPMediaPickerController *mediaPicker = [[MPMediaPickerController alloc] initWithMediaTypes:MPMediaTypeMusic];
    mediaPicker.delegate = self;
    mediaPicker.allowsPickingMultipleItems = YES;
   [self presentViewController:mediaPicker animated:YES completion:nil];

代表是

- (void)mediaPicker: (MPMediaPickerController *)mediaPicker didPickMediaItems:(MPMediaItemCollection *)mediaItemCollection
 {
   [self dismissViewControllerAnimated:YES completion:nil];
    MPMediaItem *item = [mediaItemCollection representativeItem];
    player=[[AVAudioPlayer alloc]initWithContentsOfURL:[item     valueForProperty:MPMediaItemPropertyAssetURL] error:nil];
   [player play];
 }

- (void)mediaPickerDidCancel:(MPMediaPickerController *)mediaPicker {

    [self dismissViewControllerAnimated:YES completion:nil];
}
