I have to cache images one by one passing them into an array. When I configure Controller, I got array of images from API. Images I got using Animation, every 0.1 sec I got new Image. But when I got all of them, I need to use cached images instead of load them again
Some variables for help
private var imagesCount = 0
private var nextImage = 0
private var imagesArray: [String] = []
private var isAnimating = true {
didSet {
if isAnimating {
animateImage()
}
}
}
Here I configure VC, and do imagesArray = images, then I will use only my array of urls
func configureView(images: ApiImages) {
guard let images = images.images else { return }
imagesArray = images
imagesCount = images.count
imageView.setImage(imageUrl: images[nextImage])
nextImage += 1
animateImage()
}
When I start my animation. Every 0.1 I get new one image, but after the end of cycle I want to use cached images
func animateImage() {
UIView.transition(with: self.imageView, duration: 0.1, options: .transitionCrossDissolve) { [weak self] in
guard let self = self else { return }
self.imageView.setImage(imageUrl: self.imagesArray[self.nextImage])
} completion: { [weak self] _ in
guard let self = self else { return }
if self.nextImage == self.imagesCount - 1{
//here is end of cycle
self.nextImage = 0
} else {
self.nextImage += 1
}
if self.isAnimating {
self.animateImage()
}
}
}
I use kingfisher, so what options I have to put here??
extension UIImageView {
func setImage(imageUrl: String, completion: (() -> ())? = nil) {
self.kf.setImage(with: URL(string: imageUrl), options: [.transition(.fade(0.5)), .alsoPrefetchToMemory]) { result in
completion?()
}
}
}
Thank you!
