Implemento algo como esto en mi proyecto, espero que te ayude.
Muestro todos los elementos en la vista de colección y realizo acciones en la selección, también puede obtener la URL del video seleccionado
func getVideoFromCameraRoll() {
let options = PHFetchOptions()
options.sortDescriptors = [ NSSortDescriptor(key: "creationDate", ascending: false) ]
options.predicate = NSPredicate(format: "mediaType = %d", PHAssetMediaType.video.rawValue)
videos = PHAsset.fetchAssets(with: options)
videoLibraryCV.reloadData()
}
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return videos.count
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "Cell", for: indexPath)
let asset = videos!.object(at: indexPath.row)
let width: CGFloat = 150
let height: CGFloat = 150
let size = CGSize(width:width, height:height)
cell.layer.borderWidth = 0.5
cell.layer.borderColor = UIColor.lightGray.cgColor
PHImageManager.default().requestImage(for: asset, targetSize: size, contentMode: PHImageContentMode.aspectFit, options: nil)
{ (image, userInfo) -> Void in
let imageView = cell.viewWithTag(1) as! UIImageView
imageView.image = image
let labelView = cell.viewWithTag(2) as! UILabel
labelView.text = String(format: "%02d:%02d",Int((asset.duration / 60)),Int(asset.duration) % 60)
}
return cell
}
func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) {
let asset = photos!.object(at: indexPath.row)
guard(asset.mediaType == PHAssetMediaType.Video)
else {
print("Not a valid video media type")
return
}
PHCachingImageManager().requestAVAssetForVideo(asset, options: nil, resultHandler: {
(asset: AVAsset ? , audioMix : AVAudioMix ? , info : [NSObject: AnyObject] ? ) in
let asset = asset as!AVURLAsset
print(asset.URL) // Here is video URL
})
}
Espero que funcione para ti ... :)
