一个简单的图片“翻书”，可以以翻书风格动画呈现。
DSFImageFlipbook 将翻书中的每张图片在图片的帧持续时间内呈现给翻书的所有者（使用 block 回调或 Combine Publisher）。
支持：-
- 从 GIF、电影或手动逐帧加载图像。
- 重复次数
- 速度
- 拖动
- 取消
我想在 Dock 磁贴中放置一个动画 GIF。 由于 NSDockTile 的特性，你不能直接播放一个 NSImageView 作为磁贴的 contentView - Dock 磁贴只有在你告诉它的时候才会更新（通过 display()）。
所以我需要一个类，可以在定义的时间呈现给我单独的图像，以便我可以手动更新 Dock 图像。
let flipbook = DSFImageFlipbook()
...
// Add frames manually
flipbook.addFrame(image: image1, duration: 0.5) // first frame for 0.5 seconds
flipbook.addFrame(image: image2, duration: 0.5) // second frame for 0.5 seconds
flipbook.addFrame(image: image3, duration: 0.5) // third frame for 0.5 seconds
flipbook.addFrame(image: image4, duration: 2.0) // last frame for 2.0 seconds
// And start the animation
flipbook.start() { [weak self] (frame, current, count, stop) in
// Do something with the provided frame
}
let flipbook = DSFImageFlipbook()
// Load the frames from a gif
let gif = Bundle.main.image(forResource: NSImage.Name("animation.gif"))!
_ = flipbook.loadFrames(from: gif)
...
// Use a combine sink to listen to frame changes in localFlipbook
cancellable = flipbook.publisher
.map { return $0.image }
.sink(receiveValue: { [weak self] image in
... do something with 'image'
})
// Start the animation at 2x the speed defined in the flipbook. Repeat 10 times.
flipbook.start(speed: 2, repeatCount: 10)
