[code]if self.asset.mediaSubtypes == PHAssetMediaSubtype.PhotoLive {
    let options = PHLivePhotoRequestOptions()
    options.deliveryMode = PHImageRequestOptionsDeliveryMode.HighQualityFormat
    options.networkAccessAllowed = true
    options.progressHandler = { (progress: Double, error: NSError?, stop: UnsafeMutablePointer<ObjCBool>, info: [NSObject : AnyObject]?) -> Void in
        print(progress)
    }
    PHImageManager.defaultManager().requestLivePhotoForAsset(self.asset, targetSize: self.targetSize(), contentMode: PHImageContentMode.AspectFit, options: options, resultHandler: { (livePhoto: PHLivePhoto?, info: [NSObject : AnyObject]?) -> Void in
        self.livePhotoView.livePhoto = livePhoto
        if let degradedKeyinfo = info?[PHImageResultIsDegradedKey] {
            if !degradedKeyinfo.boolValue && !self.playing {
                self.livePhotoView.startPlaybackWithStyle(PHLivePhotoViewPlaybackStyle.Hint)
            }
