Simple extension for local gifs. Gets all the images from the gif and adds it to the imageView animationImages.
extension UIImageView {
static func fromGif(frame: CGRect, resourceName: String) -> UIImageView? {
guard let path = Bundle.main.path(forResource: resourceName, ofType: "gif") else {
print("Gif does not exist at that path")
return nil
}
let url = URL(fileURLWithPath: path)
guard let gifData = try? Data(contentsOf: url),
let source = CGImageSourceCreateWithData(gifData as CFData, nil) else { return nil }
var images = [UIImage]()
let imageCount = CGImageSourceGetCount(source)
for i in 0 ..< imageCount {
if let image = CGImageSourceCreateImageAtIndex(source, i, nil) {
images.append(UIImage(cgImage: image))
}
}
let gifImageView = UIImageView(frame: frame)
gifImageView.animationImages = images
return gifImageView
}
}
To Use:
guard let confettiImageView = UIImageView.fromGif(frame: view.frame, resourceName: "confetti") else { return }
view.addSubview(confettiImageView)
confettiImageView.startAnimating()
Repeat and duration customizations using UIImageView APIs.
confettiImageView.animationDuration = 3
confettiImageView.animationRepeatCount = 1
When you are done animating the gif and want to release the memory.
confettiImageView.animationImages = nil
