Save image file path to Core Data

Question

After much research about the best way to save an image to a sqlite db in iOS, i've decided to save the filepath of the image in an entity and just reference it when it comes to displaying it as a thumbnail.

I'm using the following code to save the image taken with the camera:

    - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)snagPhoto editingInfo:(NSDictionary *)editingInfo
{
    [self.library saveImage:snagPhoto toAlbum:@"Snags" withCompletionBlock:^(NSError *error) {

        if (error) 
        {  
            NSLog(@"error");  
        } 
    }];  

    [picker dismissModalViewControllerAnimated:NO];
}

All I need to do is get the filepath of 'snagPhoto'.

在ALAssetsLibrary上使用的正确方法是writeImageToSavedPhotosAlbum:metadata:completionBlock:或writeImageToSavedPhotosAlbum:orientation:completionBlock: -这些将导致资产URL，您以后可以将其与assetForURL:resultBlock:failureBlock:以获取对图像的引用。
