iPad：访问相册时发生崩溃

Question

我正在尝试使用以下代码访问相册。它在我的iPhone或iPad上运行不到4.0版本。

  

  
• （无效）BrowsePhotoLibrary：（ID）发送方   {
  

NSArray *types = [UIImagePickerController availableMediaTypesForSourceType:
    UIImagePickerControllerSourceTypePhotoLibrary];

if ([types containsObject:(id)kUTTypeMovie])
{

    UIImagePickerController *imgPickerController = [[[UIImagePickerController alloc] init] autorelease];
    imgPickerController.delegate = self;
    imgPickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
    imgPickerController.mediaTypes = [NSArray arrayWithObject:(id)kUTTypeMovie];

    [self presentModalViewController:imgPickerController animated:YES];             
}

}

如果相册中至少有一个视频，如果相册中没有任何视频，则相同的代码会在iPad 2，4.3版本中崩溃，然后相同的代码将启动到相册。有人可以告诉我这里可能是什么原因吗？

Answer 1

我修改了imgPickerController.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
