For iOS9, ALAssetsLibrary is deprecated. So how to change it as PHPPhotoLibrary instead of ALAssets?
if (RecordedSuccessfully && recording == NO) {
//----- RECORDED SUCESSFULLY -----
NSLog(#"didFinishRecordingToOutputFileAtURL - success");
ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
if ([library videoAtPathIsCompatibleWithSavedPhotosAlbum:outputFileURL])
{
[library writeVideoAtPathToSavedPhotosAlbum:outputFileURL
completionBlock:^(NSURL *assetURL, NSError *error)
{
if (error)
{
}
}];
}
// i have tried this, but didnt work
[[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{
PHAssetChangeRequest* createAssetRequest = [PHAssetChangeRequest creationRequestForAssetFromVideoAtFileURL:outputFileURL];
NSParameterAssert(createAssetRequest);
}
completionHandler:^(BOOL success, NSError *error) {}];
}
}
// Save to the album
__block PHObjectPlaceholder *placeholder;
[[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{
PHAssetChangeRequest* createAssetRequest = [PHAssetChangeRequest creationRequestForAssetFromVideoAtFileURL:outputFileURL];
placeholder = [createAssetRequest placeholderForCreatedAsset];
} completionHandler:^(BOOL success, NSError *error) {
if (success)
{
NSLog(#"didFinishRecordingToOutputFileAtURL - success for ios9");
}
else
{
NSLog(#"%#", error);
}
}];

I found that VLC.app save video to album quickly. But my code will cost long time. Or it crash. How can I optimazed it. (compare with same large video)
Here is my code.
[[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{
assetId = [PHAssetCreationRequest creationRequestForAssetFromVideoAtFileURL:fileUrl].placeholderForCreatedAsset.localIdentifier;
} completionHandler:^(BOOL success, NSError * _Nullable error) {
if (!success) {
if(onError)onError(error);
return ;
}
PHAssetCollection *collection = [self getAlbumCollection:collectionStr];
[[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{
PHAssetCollectionChangeRequest *request = [PHAssetCollectionChangeRequest changeRequestForAssetCollection:collection];
PHAsset *asset = [PHAsset fetchAssetsWithLocalIdentifiers:#[assetId] options:nil].firstObject;
[request addAssets:#[asset]];
} completionHandler:^(BOOL success, NSError * _Nullable error) {
if (!success) {
if(onError)onError(error);
return;
}
if(onComplete)onComplete(fileUrl);
}];
}];
In my app I used edit pic and saved in custom folder in Gallery called "Fab". now is there anything to delete that image from folder? I have found different solution but they require asset URL. I used Photos framework so how to get asset url for particular image for deletion ?
PHAsset *tempPhasset = [_arrImageForAssetCameraRoll objectAtIndex:index]; // here pass your PHasset that you want to delete .
NSString *localStr=tempPhasset.localIdentifier;
NSRange range = [localStr rangeOfString:#"/"];
NSString *newString = [localStr substringToIndex:range.location];
NSString *appendedString=[NSString stringWithFormat:#"%#%#%#",#"assets-library://asset/asset.JPG?id=",newString,#"&ext=JPG"];
NSLog(#"%# phasset ",appendedString);
NSURL *deleteurl = [NSURL URLWithString:appendedString];
NSArray *arrDelete = [[NSArray alloc] initWithObjects:deleteurl , nil];
PHFetchResult *asset = [PHAsset fetchAssetsWithALAssetURLs:arrDelete options:nil];
[asset enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
NSLog(#"%#",[obj class]);
[[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{
BOOL req = [obj canPerformEditOperation:PHAssetEditOperationDelete];
if (req) {
NSLog(#"true");
[PHAssetChangeRequest deleteAssets:#[obj]];
}
} completionHandler:^(BOOL success, NSError *error) {
NSLog(#"Finished Delete asset. %#", (success ? #"Success." : error));
if (success) {
NSLog(#"delete successfully");
}else{
NSLog(#"delete Cancel");
}
}];
Any query about my code then put comment .
Happy Coding.
Try this below code
ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
[library writeImageToSavedPhotosAlbum:[viewImage CGImage] orientation:(ALAssetOrientation)[viewImage imageOrientation] completionBlock:^(NSURL *assetURL, NSError *error){
if (error) {
NSLog(#"error");
} else {
NSLog(#"url %#", assetURL);
}
}];
will return url for saved image.
I have more than 10 videos url in one view which is coming from Web service. I am showing these videos thumbnails in UITableview.
I am Using following code where I m Saving These Videos to gallery in particular folder
This is my code::
NSURL *url = [NSURL URLWithString:Urlstr];
NSData *data = [NSData dataWithContentsOfURL:url];
// Write it to cache directory
NSString *path = [[NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) objectAtIndex:0] stringByAppendingPathComponent:#"file.mov"];
[data writeToFile:path atomically:YES];
// After that use this path to save it to PhotoLibrary
ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
[library addAssetsGroupAlbumWithName:#"MyFolderName" resultBlock:^(ALAssetsGroup *group)
{
//How to get the album URL?
// saving the video in gallery though file path and document directory
[library writeVideoAtPathToSavedPhotosAlbum:[NSURL fileURLWithPath:path] completionBlock:^(NSURL *assetURL, NSError *error) {
if (error) {
NSLog(#"%#", error.description);
}else {
NSLog(#"Done :)");
}
}];
}
failureBlock:^(NSError *error) {
//Handle the error
}];
Now the issues is it is not saving my video to My folder. But it creates the folder and saving the video in default video folder of gallery.
Anyone please suggest me why it going like this.
- (void)createAlbumInPhotosLibrary:(NSString *)photoAlbumName videoAtFile:(NSURL *)videoURL {
// RELIVIT_moments
__block PHFetchResult *photosAsset;
__block PHAssetCollection *collection;
__block PHObjectPlaceholder *placeholder;
// Find the album
PHFetchOptions *fetchOptions = [[PHFetchOptions alloc] init];
fetchOptions.predicate = [NSPredicate predicateWithFormat:#"title = %#", photoAlbumName];
collection = [PHAssetCollection fetchAssetCollectionsWithType:PHAssetCollectionTypeAlbum
subtype:PHAssetCollectionSubtypeAny
options:fetchOptions].firstObject;
// Create the album
if (!collection)
{
[[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{
PHAssetCollectionChangeRequest *createAlbum = [PHAssetCollectionChangeRequest creationRequestForAssetCollectionWithTitle:photoAlbumName];
placeholder = [createAlbum placeholderForCreatedAssetCollection];
} completionHandler:^(BOOL success, NSError *error) {
if (success)
{
PHFetchResult *collectionFetchResult = [PHAssetCollection fetchAssetCollectionsWithLocalIdentifiers:#[placeholder.localIdentifier]
options:nil];
collection = collectionFetchResult.firstObject;
[self saveVideoInRelivitFolderSetPlaceHolder:placeholder photosAsset:photosAsset collection:collection VideoAtFile:videoURL];
}
}];
} else {
[self saveVideoInRelivitFolderSetPlaceHolder:placeholder photosAsset:photosAsset collection:collection VideoAtFile:videoURL];
}
}
- (void)saveVideoInRelivitFolderSetPlaceHolder:(PHObjectPlaceholder *)placeholderLocal photosAsset:(PHFetchResult *)photosAssetLocal collection:(PHAssetCollection *)collectionLocal VideoAtFile:(NSURL *)videoURL {
__block PHFetchResult *photosAsset = photosAssetLocal;
__block PHAssetCollection *collection = collectionLocal;
__block PHObjectPlaceholder *placeholder = placeholderLocal;
// Save to the album
[[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{
PHAssetChangeRequest *assetRequest = [PHAssetChangeRequest creationRequestForAssetFromVideoAtFileURL:videoURL];
placeholder = [assetRequest placeholderForCreatedAsset];
photosAsset = [PHAsset fetchAssetsInAssetCollection:collection options:nil];
PHAssetCollectionChangeRequest *albumChangeRequest = [PHAssetCollectionChangeRequest changeRequestForAssetCollection:collection
assets:photosAsset];
[albumChangeRequest addAssets:#[placeholder]];
} completionHandler:^(BOOL success, NSError *error) {
if (success)
{
NSLog(#"done");
}
else
{
NSLog(#"%#", error.localizedDescription);
}
}];
}
So I've been trying to accomplish this for quite some time now, but unfortunately none of the solutions posted on stack, or the ones I tried to write myself seem to work. I am building an application that allows users to take pictures and videos, and other users to save these down. I am using AWS services to save the content. Although the returned URL using NSLog, shows me the video when copy/pasting it to a browser, it refuses to save to the camera roll. Saving pictures however works fine.
So far I tried the following:
-(void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
if([mediaType isEqualToString:(NSString *)kUTTypeMovie]) {
NSURL *movieUrl = [info objectForKey:UIImagePickerControllerMediaURL];
ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
[library writeVideoAtPathToSavedPhotosAlbum:movieUrl completionBlock:^(NSURL *assetURL, NSError *error){
if(error) {
NSLog(#"CameraViewController: Error on saving movie : %# {imagePickerController}", error);
} else {
NSLog(#"URL: %#", assetURL);
}
}];
}
}
and also:
if (UIVideoAtPathIsCompatibleWithSavedPhotosAlbum(self.post.mediaUrl)) {
UISaveVideoAtPathToSavedPhotosAlbum(self.post.mediaUrl, self, #selector(video:finishedSavingWithError:contextInfo:),#selector(video:finishedSavingWithError:contextInfo:));
} else {
NSLog(#"Incompatible File apparently");
}
Any advice? Thanks!
*Updated on April 6, 2016 to make use of modern frameworks
Import the following in wherever you place this method:
#import <AssetsLibrary/AssetsLibrary.h>
#import Photos
Then call method as following:
[yourClass saveMedia:(*your image*) video:(*your video url*)]
Hope this helps people, feel free to comment with questions.
+ (void)saveMedia:(UIImage *)image video:(NSURL *)video_url {
if(image) {
if(!image) {
return;
}
[[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{
PHAssetChangeRequest *changeRequest = [PHAssetChangeRequest creationRequestForAssetFromImage:image];
NSLog(#"%#", changeRequest.description);
} completionHandler:^(BOOL success, NSError *error) {
if (success) {
NSLog(#"saved down");
} else {
NSLog(#"something wrong");
}
}];
} else if (video_url) {
if([video_url absoluteString].length < 1) {
return;
}
NSLog(#"source will be : %#", video_url.absoluteString);
NSURL *sourceURL = video_url;
if([[NSFileManager defaultManager] fileExistsAtPath:[video_url absoluteString]]) {
[[[ALAssetsLibrary alloc] init] writeVideoAtPathToSavedPhotosAlbum:video_url completionBlock:^(NSURL *assetURL, NSError *error) {
if(assetURL) {

} else {

}
}];
} else {

return;
}

In Objective - C
Add this in .h/.m file
#import <Photos/Photos.h>
Save Video to Camera Roll:
[[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{
[PHAssetChangeRequest creationRequestForAssetFromVideoAtFileURL:videoUrl];
}
completionHandler:^(BOOL success, NSError *error) {
if (success)
{
NSLog(#"Video saved");
}else{
NSLog(#"%#",error.description);
}
}];
How can I export video using AVAssetExportSession and save result video in a custom album, for example My Own Videos?
First you need to create a folder:
ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
NSString *folderName = #"My Own Videos";
[library addAssetsGroupAlbumWithName:folderName
resultBlock:^(ALAssetsGroup *group)
{
NSLog(#"Added folder:%#", folderName);
}
failureBlock:^(NSError *error)
{
NSLog(#"Error adding folder");
}];
Then, find the folder:
__block ALAssetsGroup* folder;
[library enumerateGroupsWithTypes:ALAssetsGroupAlbum
usingBlock:^(ALAssetsGroup *group, BOOL *stop)
{
if ([[group valueForProperty:ALAssetsGroupPropertyName] isEqualToString:folderName])
{
folder = group;
}
}
failureBlock:^(NSError* error)
{
// Error handling.
}];
And add your video to it. Save the asset to Library:
AVURLAsset *videoAsset = ...
AVAssetExportSession *exportSession = [[AVAssetExportSession alloc] initWithAsset:videoAsset
presetName:AVAssetExportPreset1280x720];
exportSession.outputURL = [[NSFileManager defaultManager] URLForInterviewWithFileName:newFileName];
exportSession.outputFileType = AVFileTypeMPEG4;
[exportSession exportAsynchronouslyWithCompletionHandler:^{ ...
And put it into the album:
[folder addAsset:asset];
Hope it helps.
after export session (when you have the url)
-(void)saveVideoUrl:(NSURL*)url toCollection:(NSString *)collectionTitle {
NSLog(#"entered %s", __PRETTY_FUNCTION__);
__block PHFetchResult *photosAsset;
__block PHAssetCollection *collection;
__block PHObjectPlaceholder *placeholder;
// Find the album
PHFetchOptions *fetchOptions = [[PHFetchOptions alloc] init];
fetchOptions.predicate = [NSPredicate predicateWithFormat:#"title = %#", collectionTitle];
// this is how we get a match for album Title held by 'collectionTitle'
collection = [PHAssetCollection fetchAssetCollectionsWithType:PHAssetCollectionTypeAlbum subtype:PHAssetCollectionSubtypeAny options:fetchOptions].firstObject;
// check if album exists
if (!collection)
{
[[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{
NSLog(#" Album did not exist, now creating album: %#",collectionTitle);
// Create the album
PHAssetCollectionChangeRequest *createAlbum = [PHAssetCollectionChangeRequest creationRequestForAssetCollectionWithTitle:collectionTitle];
placeholder = [createAlbum placeholderForCreatedAssetCollection];
} completionHandler:^(BOOL didItSucceed, NSError *error) {
if (didItSucceed)
{
PHFetchResult *collectionFetchResult = [PHAssetCollection fetchAssetCollectionsWithLocalIdentifiers:#[placeholder.localIdentifier] options:nil];
collection = collectionFetchResult.firstObject;
}
}];
}
// Save to the album
[[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{
PHAssetChangeRequest *assetRequest = [PHAssetChangeRequest creationRequestForAssetFromVideoAtFileURL:url];
placeholder = [assetRequest placeholderForCreatedAsset];
photosAsset = [PHAsset fetchAssetsInAssetCollection:collection options:nil];
PHAssetCollectionChangeRequest *albumChangeRequest = [PHAssetCollectionChangeRequest changeRequestForAssetCollection:collection assets:photosAsset];
[albumChangeRequest addAssets:#[placeholder]];
} completionHandler:^(BOOL didItSucceed, NSError *error) {
if (didItSucceed)
{ // if YES
NSLog(#" Looks like Image was saved in camera Roll as %#", placeholder.localIdentifier);
NSLog(#"placeholder holds %#", placeholder.debugDescription );
}
else
{
NSLog(#"%#", error);
}
}];
}
