Animated GIF library for iPhone. Based on original work by Martin van Spanje.
Animated and transparent GIF’s for iPhone made easy! on http://blog.stijnspijker.nl/
I recently started developing for iPhone, and I was looking to include some simple animations into my applications, like a typical AJAX loading GIF when I’m waiting for my stream of data to come in.
It surprised me that nothing was available! After a lot of searching I found a block of code by Martin van Spanje from P-Edge. It was based on some PHP code, splitting an animated GIF in subframes.
The code worked, Martin stated it needed to be checked and optimized. So I went to work. I upped the code to the GIF 89a standards, I created a class out of it. Best of all, I got animation working WITH transparency! I believe in Apple’s idea of simplicity, so I made a set of interfaces that -anyone- should be able to use.
// First example, a local file
NSURL* firstUrl = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"apple_logo_animated" ofType:@"gif"]];
UIImageView * firstAnimation = [AnimatedGif getAnimationForGifAtUrl: firstUrl];
// Second example, through HTTP
NSURL * secondUrl = [NSURL URLWithString:@"http://www.gifs.net/Animation11/Food_and_Drinks/Fruits/Apple_jumps.gif"];
UIImageView * secondAnimation = [AnimatedGif getAnimationForGifAtUrl: secondUrl];
// Add them to the view.
[theFirstAnimatedGif addSubview:firstAnimation];
[theSecondAnimatedGif addSubview:secondAnimation];
