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’.

The proper method to use on ALAssetsLibrary is writeImageToSavedPhotosAlbum:metadata:completionBlock: or writeImageToSavedPhotosAlbum:orientation:completionBlock: — these will lead to an asset URL that you can later use with assetForURL:resultBlock:failureBlock: to get a reference to the image.
