iPad：訪問相冊時發生崩潰

Question

我正嘗試使用以下代碼訪問相冊。它可以在我的iPhone或iPad版本不到4.0的情況下正常工作。

• （無效）BrowsePhotoLibrary：（ID）發送方 {

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];    
} 

}

在ipad 2相同的代碼崩潰，4.3版本，如果有ATLEAST一個視頻可用於相冊，如果相冊沒有任何視頻，則相同的代碼會啓動到相冊。有人可能會建議這是什麼原因嗎？

Answer 1

我修改了它通過更改imgPickerController.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
