Load the images in function loadImage and call it in background as follows...So your view will appear and images will be loaded in background

     [self performSelectorInBackground:@selector(loadImag) withObject:nil];

You can use GCD to load those images asynchronously

I don't know how is the layout of your viewcontrollers but you should put in the viewDidLoad of your ViewController which displays the images something like this.

dispatch_queue_t queue = 
              dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0);
dispatch_async(queue, ^{
  theImageView.image = // Whatever your method to grab the image will be
});
