You can use Core Graphics to draw the different JPEGs into a new CGImage. You can use ImageIO to write the CGImage out to a GIF.

thanks, but how can I make it change/animate between the images? so that it shows 1 image for a few seconds, then the next image etc

That's more like making a slideshow. not really showing just a gif.

The gif ->

  // create the view that will execute our animation
    /*
    UIImageView* loadingScreen = [[UIImageView alloc] initWithFrame:self.window.frame];
    
    // load all the frames of our animation
    loadingScreen.animationImages = [NSArray arrayWithObjects:    
                                    [UIImage imageNamed:@"C64-1.png"],
                                    [UIImage imageNamed:@"C64-2.png"],nil];
    
    // all frames will execute in 1.75 seconds
    loadingScreen.animationDuration = 1.75;
    // repeat the annimation forever
    loadingScreen.animationRepeatCount = 3;
    
    // start animating
    [loadingScreen startAnimating];
    // add the animation view to the main window 
    [self.window addSubview:loadingScreen];
    */

About the slideshow thing, well that's a bit too much to just post.
