Live Photos

WWDC 15 没有发表，2015 年 9 月的 Special Event 上随 iPhone 6s 一同发表。

iPhone 6/6s 可以拍摄，内：3 秒时间的视频和一张 JPG 组成，iOS 9 以后的设备都可以播放。

iOS 9.1 中 live photos 有关的 API 已经公开：

• 显示，再生：PHLivePhotoView
• 分享：PHAssetResource

对 Live Photo 做编辑的时候，需要注意对所有的 frame 都作出调整。

• Vine 支持 6 秒短视频，相比于 Vine，Live Photo 更加内敛。现时点，Facebook 和 Instagram 暂时都还没有对应 Live Photo。

向 Simulator 中传送 Live Photo 的方式：

1. iPhone 拍摄
2. iPhone -> 传输到照片 app
3. 使用 iCloud 导入，不能直接 drag & drop (麻烦)。

也许可以考虑写个工具来在实机和 Simulator 之间进行转换。
