XLYAnimatedImage

play animated images using player. Easy to associated with any thing which can draw UIImage.

support speed, skipFrames, displayLinkFrameInterval config. Auto preload and clear cache if needed.

updates

updated to swift 2.2 and refined some code.

swift 2

swift 2.2 is required. And better use framework.

Quick look

In most scene, developer will async load image data rather than other ways.

import XLYAnimatedImage

// get data
let data = ... // load from some where, network or ...

// scale has a default value equals to screen scale, or you can specify it.
let animatedImage = AnimatedDataImage(data: data, scale: default)

// setup player and keep a reference.
let player = AnimatedImagePlayer(display: {[weak self] image, index in
        self?.image = image
    },
    stop: {[weak self] in
        self?.image = nil
    })

// setup image
player.image = animatedImage

// set replay to true will replay animatedImage even if it's same object.
player.setImage(image, replay: true)

// config player
player.onTimeElapse = { [unowned self] time in
    self.timeSlider.value = Float(time / self.imageView.xly_animatedImagePlayer!.totalTime)
}

player.speed = 2
player.skipFrames = true
player.displayLinkFrameInterval = 2

or use a helper extension method on UIImageView.

// set image
imageView.xly_setAnimatedImage(animatedImage, replay: true)

// get player and then config as you wish
let player = imageView.xly_animatedImagePlayer

see more in demo.

feature

• uses protocol so that anyone can make impl of AnimatedImage and can be playered with player.
• player supports paused, speed, skipFrames, displayLinkFrameInterval config.
• player provides frameIndex for current image frame index, time for current playing time.
• player can move to any index by calling moveToFrameAtIndex(_:), can move to any time by calling moveToTime(_:).
• player uses display callback for you to display a frame, stop callback for you to stop playing an image, and onTimeElapse to nofify time changing.

• also at any time, you can change callbacks and image, and can also refresh an image’s playing by set param ‘replay’ to true.

  no apng support now cause I’m waiting for apple to support in iOS device. if you need it, you can write your own impl, it’s not difficult.
