  1. If you have a serie of images you want to animate you can easily do it with UIImageView:

    UIImage *blur5 = [UIImage imageNamed:@"blur5.png"];
    UIImage *blur6 = [UIImage imageNamed:@"blur6.png"];

    self.imageView.animationImages = [[NSArray alloc] initWithObjects:blur5, blur6, nil];
    self.imageView.animationRepeatCount = 5;
    [self.imageView startAnimating];

    I found this easier than trying to use UIWebView.

  2. UIWebView does not properly display all GIF content. You need to use a UIImageView, but the iPhone OS does not support animated GIFS and only displays the first frame.

    So you need to extract all of the other frames first.

    Crude example code here:

  3. You can use source at
    It has a GIF decoder that you can use directly to get solution.
    I successfully used it. But it have some problems with transparency.

  4. Excellent article on 'Animating gif and animating images'

  5. one other option is to decode the gif in your application and then "frame serve" it to a opengl object, this way is less likely to run out of memory for large gifs
