iOS ALAsset is not refreshed after image is modified in photo library

Question

My app can take image from photo library. For the first time app open, it can take latest image.

But after I open app, go to background, open photo library and modify image, and come back to app, when user choose photo, it is not the latest image.

When I log image url in assets, it show the same one before and after modify image. Is it supposed to be same? Or different after image is modified?

Asset = ALAsset - Type:Photo, URLs:assets-library://asset/asset.PNG?id=4E226E36-2D9C-449C-92AE-5036938603A9&ext=PNG

- (void) loadAssetsForGroup: (ALAssetsGroup*) group withCompletionHandler: (void (^)(NSArray*)) completionHandler {
    __strong NSMutableArray* assets = [NSMutableArray array];

    [group enumerateAssetsUsingBlock: ^(ALAsset* result, NSUInteger index, BOOL* stop) {
         if (!result) {
             completionHandler(assets);
             return;
         }
         [assets addObject: result];
     }];
}

url supposed to be different but you need to load it again every time you access the photos. — Mahesh Agrawal, Aug 17 '16 at 06:32
I call my method loadAssetsForGroup though. At that time, shall I get latest image? Or how to load again properly? — Khant Thu Linn, Aug 17 '16 at 06:35
are you using ALImagePicker? if so, alloc init it again and request for images when opening — Mahesh Agrawal, Aug 17 '16 at 06:38
I am using https://github.com/foby/FOAssetPicker But I init again though. — Khant Thu Linn, Aug 17 '16 at 06:40
try http://stackoverflow.com/a/35742806/4030971 instead of the library. may be the library cashing somewhere. try native code. — Mahesh Agrawal, Aug 17 '16 at 06:46
