iOS的错误使用writeImageToSavedPhotosAlbum

-1

时，这是我的错误，当我尝试编译我的项目：iOS的错误使用writeImageToSavedPhotosAlbum

Undefined symbols for architecture armv7: 
    "_writeImageToSavedPhotosAlbum", referenced from: 
    -[AddNewPhotoViewController imagePickerController:didFinishPickingMediaWithInfo:] in AddNewPhotoViewController.o

调用writeImageToSavedPhotosAlbum当我得到的错误。我怀疑这个错误与不导入必要的框架有关，但我不知道要导入什么。

任何帮助？

这里是我的writeImageToSavedPhotosAlbum代码：

- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info 
{ 
    // Access the uncropped image from info dictionary 
    UIImage *image = [info objectForKey:@"UIImagePickerControllerOriginalImage"]; 

    [self dismissModalViewControllerAnimated:YES]; 

    [_CameraOutput setImage:image]; 

    writeImageToSavedPhotosAlbum(image, nil, @selector(image:didFinishSavingWithError:contextInfo:)); 
}

编辑＃2 我已经包含在我的.m文件以下导入：

#import <AssetsLibrary/AssetsLibrary.h>

显示你的代码中调用'writeImageToSavedPhotosAlbum'。 – 2012-08-02 08:14:29

在问你有人建议你使用'writeImageToSavedPhotosAlbum'的问题，他们提供了一个链接到[文档]（https://developer.apple.com/library/ ios /＃documentation/AssetsLibrary/Reference/ALAssetsLibrary_Class/Reference/Reference.html＃// apple_ref/occ/instm/ALAssetsLibrary/writeImageToSavedPhotosAlbum：metadata：completionBlock :)它告诉你需要包含哪些框架 – 2012-08-02 08:18:18

writeImageToSavedPhotosAlbum是ALAssetsLibrary的方法，你必须这样做

ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init]; 
[library writeImageToSavedPhotosAlbum:[image CGImage] orientation:(ALAssetOrientation)[image imageOrientation] completionBlock:your_completion_block];

感谢martin，尽管我仍然需要包含AssetsLibrary框架，但我现在已经完成了:) – 2012-08-02 08:31:02
