// An `FLAnimatedImageView` can take an `FLAnimatedImage` and plays it automatically when in view hierarchy and stops when removed.
|
||
|
|
// The animation can also be controlled with the `UIImageView` methods `-start/stop/isAnimating`.
|
||
|
|
// It is a fully compatible `UIImageView` subclass and can be used as a drop-in component to work with existing code paths expecting to display a `UIImage`.
|
||
|
|
// Under the hood it uses a `CADisplayLink` for playback, which can be inspected with `currentFrame` & `currentFrameIndex`.

|
// And vice versa, setting `animatedImage` will initially populate the `[UIImageView.image]` to its `posterImage` and then start animating and hold `currentFrame`.
