Ipad Application how to get images from custom album

I am developing an iPad application in which I have saved images to custom album using This.

Now I want to get all the images from that custom folder and I need to show all those in a animated UIImageView.

I know how to set animation but I want to know how to get all the images from particular custom folder.

See this code I used to load the images from the custom album. I have used the same sample code to store my images in custom album.

NSMutableArray *tempArray = [[NSMutableArray alloc] init];
    self.assetGroups = tempArray;

    library = [[ALAssetsLibrary alloc] init];      

    // Load Albums into assetGroups

        // Group enumerator Block
        void (^assetGroupEnumerator)(ALAssetsGroup *, BOOL *) = ^(ALAssetsGroup *group, BOOL *stop) 
        {
            if (group == nil) 
            {
                return;
            }
            if([[group valueForProperty:ALAssetsGroupPropertyName] isEqualToString:kAlbumName])
            {
                [self.assetGroups addObject:group];
                [self reloadTableView];
                return;
            }
        };

        // Group Enumerator Failure Block
        void (^assetGroupEnumberatorFailure)(NSError *) = ^(NSError *error) {

            CustomAlertView * alert = [[CustomAlertView alloc] initWithTitle:@"Error" message:[NSString stringWithFormat:@"Album Error: %@ - %@", [error localizedDescription], [error localizedRecoverySuggestion]] delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil];
            [alert show];

            NSLog(@"A problem occured %@", [error description]);                                     
        };  

        // Enumerate Albums
        [library enumerateGroupsWithTypes:ALAssetsGroupAll
                               usingBlock:assetGroupEnumerator 
                             failureBlock:assetGroupEnumberatorFailure];

Here the kAlbumName is one string ivar which contains the custom album name.

EDIT:1

Above code just gives you the whole album selected with all it photos now to get those photos from album use the following code 

[self.assetGroup enumerateAssetsUsingBlock:^(ALAsset *result, NSUInteger index, BOOL *stop) 
     {         
         if(result == nil) 
             return;
     CGRect viewFrames = kThumbSize;//CGRectMake(0, 0, 75, 75);
         UIImageView *assetImageView = [[UIImageView alloc] initWithFrame:viewFrames];
        [assetImageView setContentMode:UIViewContentModeScaleToFill];
        [assetImageView setImage:[UIImage imageWithCGImage:(__bridge CGImageRef)([result originalAsset])]];
     }];

NOTE: Instead of kThumbSize define your CGRectMake() as commented.

Enjoy coding :) Happy Day :)
