Image loading delay in minutes when 100 of images to load

[kamabhavik]

am using FastImageCache Caching Library for loading and caching the images asynchronously.

i have a requirement to load around 100 images in one view at once with the following code in For Loop.

FICDPhoto *photo = [[FICDPhoto alloc] init];
[photo setSourceImageURL:[NSURL URLWithString:logo]];

                    [[FICImageCache sharedImageCache] retrieveImageForEntity:photo withFormatName:FICDPhotoSquareImage32BitBGRAFormatName completionBlock:^(id<FICEntity> entity, NSString *formatName, UIImage *image) {

                        if(btn.tag==65){

                        }
                        [btn setImage:image forState:UIControlStateNormal];
                    }];

now the issue is it taking more then one minute to load images.its not showing images as one by one bu rather its just showing all images at once after one minute of delay..

I want to solve this issue by showing images as downloaded one by one rather then showing all images at once
