How to save movie to custom named album in swift
in lens C, you can save the video to a custom photo album using code similar to the following
-(void)saveImage:(UIImage*)image
toAlbum:(NSString*)albumName
withCompletionBlock:(SaveImageCompletion)completionBlock;
I can't figure out how to do this quickly when I look at the definition of ALAssetsLibrary. I don't see any call to the toAlum or savedImage function. I don't seem to understand this?

Here is the code I used
var albumFound : Bool = false
var assetCollection: PHAssetCollection!
var photosAsset: PHFetchResult!
var assetThumbnailSize:CGSize!
// Create the album if does not exist (in viewDidLoad)
if let first_Obj:AnyObject = collection.firstObject{
//found the album
self.albumFound = true
self.assetCollection = collection.firstObject as PHAssetCollection
}else{
//Album placeholder for the asset collection, used to reference collection in completion handler
var albumPlaceholder:PHObjectPlaceholder!
//create the folder
NSLog("\nFolder \"%@\" does not exist\nCreating now...", albumName)
PHPhotoLibrary.sharedPhotoLibrary().performChanges({
let request = PHAssetCollectionChangeRequest.creationRequestForAssetCollectionWithTitle(albumName)
albumPlaceholder = request.placeholderForCreatedAssetCollection
},
completionHandler: {(success:Bool, error:NSError!)in
NSLog("Creation of folder -> %@", (success ? "Success":"Error!"))
self.albumFound = (success ? true:false)
if(success){
let collection = PHAssetCollection.fetchAssetCollectionsWithLocalIdentifiers([albumPlaceholder.localIdentifier], options: nil)
self.assetCollection = collection?.firstObject as PHAssetCollection
}
})
}
let bundle = NSBundle.mainBundle()
let myFilePath = bundle.pathForResource("highlight1", ofType: "mov")
let videoURL:NSURL = NSURL.fileURLWithPath(myFilePath!)!
let priority = DISPATCH_QUEUE_PRIORITY_DEFAULT
dispatch_async(dispatch_get_global_queue(priority, 0), {
PHPhotoLibrary.sharedPhotoLibrary().performChanges({
//let createAssetRequest = PHAssetChangeRequest.creationRequestForAssetFromImage
let createAssetRequest = PHAssetChangeRequest.creationRequestForAssetFromVideoAtFileURL(videoURL)
let assetPlaceholder = createAssetRequest.placeholderForCreatedAsset
let albumChangeRequest = PHAssetCollectionChangeRequest(forAssetCollection: self.assetCollection, assets: self.photosAsset)
albumChangeRequest.addAssets([assetPlaceholder])
}, completionHandler: {(success, error)in
dispatch_async(dispatch_get_main_queue(), {
NSLog("Adding Image to Library -> %@", (success ? "Sucess":"Error!"))
//picker.dismissViewControllerAnimated(true, completion: nil)
})
})
})
Keep in mind that I am doing this copying a file from my package to this album (by pre-filling it with a video)
