I found its solutions my self.

+ (ALAssetsLibrary *)defaultAssetsLibrary {
    static dispatch_once_t pred = 0;
    static ALAssetsLibrary *library = nil;
    dispatch_once(&pred, ^{
        library = [[ALAssetsLibrary alloc] init];
    });
    return library;
}

-(void)loadAssets{
    NSMutableArray *unSortArray = [[NSMutableArray alloc] init];
    ALAssetsLibrary *library = [MomentsVCTR defaultAssetsLibrary];
    [library enumerateGroupsWithTypes:ALAssetsGroupAll usingBlock:^(ALAssetsGroup *group, BOOL *stop) {
        if (group == nil) {
            NSLog(@"Done!");
            [self manageLocalAssets:unSortArray];
        }
        [group setAssetsFilter:[ALAssetsFilter allAssets]];
        [group enumerateAssetsWithOptions:NSEnumerationReverse usingBlock:^(ALAsset *alAsset, NSUInteger index, BOOL *innerStop) {
            if (alAsset) {
                [unSortArray addObject:alAsset];
            }

        }];
    } failureBlock: ^(NSError *error) {
        NSLog(@"No groups: %@",error);
    }];
}

-(void)manageLocalAssets:(NSMutableArray*)unSortArray{
    NSMutableArray *_resultArray = [[NSMutableArray alloc] init];
    NSDateFormatter *df = [[NSDateFormatter alloc] init];
    [df setDateFormat:@"dd-MMM-yyyy"];
    NSLog(@"in loadassets");
    NSSortDescriptor *descriptor=[[NSSortDescriptor alloc] initWithKey:@"date" ascending:NO];
    NSArray *descriptors=[NSArray arrayWithObject: descriptor];
    NSArray *reverseOrder=[unSortArray sortedArrayUsingDescriptors:descriptors];

    for (int k=0; k
