媒体库访问
虽然没有查看是否开启权限的接口，但是还是需要在
Info.plist中添加说明。
- 简单调用实例
- (IBAction)chooseMediaItem:(id)sender {
MPMediaPickerController *mpc = [[MPMediaPickerController alloc]initWithMediaTypes:MPMediaTypeMusic];
mpc.delegate = self;
mpc.prompt =@"Please select a music";
mpc.allowsPickingMultipleItems= NO;
[self presentViewController:mpc animated:YES completion:nil];
}
#pragma mark - MPMediaPickerController delegate
- (void)mediaPicker:(MPMediaPickerController *)mediaPicker didPickMediaItems:(MPMediaItemCollection *)mediaItemCollection{
/*insert your code*/
MPMediaItem *mediaItem = [[mediaItemCollection items] objectAtIndex:0];
self.item = mediaItem;
[self dismissViewControllerAnimated:YES completion:nil];
}
- (void)mediaPickerDidCancel:(MPMediaPickerController *)mediaPicker
{
[self dismissViewControllerAnimated:YES completion:nil];
}
这里特别注意权限请求时需要在
Info.plist中添加对应的权限请求说明。如下所示
