Putting videos in one specific Album in camera roll - ios

Question

I am creating a specific album in my camera roll.. But for my every run, its creating a new album in my camera roll instead of putting the videos together to the same album.. Ideas?
__block PHObjectPlaceholder *assetCollectionPlaceholder;
[[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{
// Create new album.
[[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{
PHAssetCollectionChangeRequest *createAlbumRequest = [PHAssetCollectionChangeRequest creationRequestForAssetCollectionWithTitle:#"Eye Movement"];
assetCollectionPlaceholder = createAlbumRequest.placeholderForCreatedAssetCollection;
} completionHandler:^(BOOL success, NSError *error) {
if (success) {
PHFetchResult *fetchResult = [PHAssetCollection fetchAssetCollectionsWithLocalIdentifiers:#[assetCollectionPlaceholder.localIdentifier] options:nil];
PHAssetCollection *assetCollection = fetchResult.firstObject;
// Add it to the photo library
[[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{
PHAssetChangeRequest* createAssetRequest = [PHAssetChangeRequest creationRequestForAssetFromVideoAtFileURL:outputFileURL];
PHAssetCollectionChangeRequest* assetRequest = [PHAssetCollectionChangeRequest changeRequestForAssetCollection:assetCollection];
[assetRequest addAssets:#[[createAssetRequest placeholderForCreatedAsset]]];
//PHAssetCollectionChangeRequest *assetCollectionChangeRequest = [PHAssetCollectionChangeRequest changeRequestForAssetCollection:assetCollection];
//[assetCollectionChangeRequest addAssets:#[[createAssetRequest placeholderForCreatedAsset]]];
} completionHandler:^(BOOL success, NSError *error) {
if (!success) {
NSLog(#"Error creating asset: %#", error);
}
}];
} else {
//NSLog(#"Error creating album: %#", error);
NSLog(#"didFinishRecordingToOutputFileAtURL - success for ios9");
}
}];

Answer 1

You have to check to see if the album is created first, then tell the app to create the album if it does not exist.
__block PHFetchResult *photosAsset;
__block PHAssetCollection *collection;
__block PHObjectPlaceholder *placeholder;
// Find the album
PHFetchOptions *fetchOptions = [[PHFetchOptions alloc] init];
fetchOptions.predicate = [NSPredicate predicateWithFormat:#"title = %#", #"Your Album Name Here"];
collection = [PHAssetCollection fetchAssetCollectionsWithType:PHAssetCollectionTypeAlbum
subtype:PHAssetCollectionSubtypeAny
options:fetchOptions].firstObject;
// Create the album
if (!collection)
{
[[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{
PHAssetCollectionChangeRequest *createAlbum = [PHAssetCollectionChangeRequest creationRequestForAssetCollectionWithTitle:#"Your Album Name Here"];
placeholder = [createAlbum placeholderForCreatedAssetCollection];
} completionHandler:^(BOOL success, NSError *error) {
if (success)
{
PHFetchResult *collectionFetchResult = [PHAssetCollection fetchAssetCollectionsWithLocalIdentifiers:#[placeholder.localIdentifier]
options:nil];
collection = collectionFetchResult.firstObject;
}
}];
}
