-(void)loadImagelist{ 
    void (^assetEnumerator)(ALAsset *, NSUInteger, BOOL *) = ^(ALAsset *theAsset, NSUInteger index, BOOL *stop) { 
    if(theAsset != NULL) { 
     NSString *date = [theAsset valueForProperty: ALAssetPropertyDate]; 
     //if date == xxx add to list 
    } 
    }; 

    void (^assetGroupEnumerator)(ALAssetsGroup *, BOOL *) = ^(ALAssetsGroup *group, BOOL *stop) { 
     if(group != nil) { 
     [group setAssetsFilter:[ALAssetsFilter allPhotos]]; 
     [group enumerateAssetsUsingBlock:assetEnumerator]; 
    } 
    }; 

    ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init]; 
    [library enumerateGroupsWithTypes:ALAssetsGroupSavedPhotos usingBlock:assetGroupEnumerator failureBlock: ^(NSError *error) { 
     NSLog(@"Failure"); 
    }]; 
}
