I've been using this library for a while and since I got it working correctly I haven't had any issues.

However, now I'm noticing on iOS 9 (now running WKWebView instead of UIWebView, not sure if that makes a difference), that when I save, it saves to my custom album, camera roll (not a problem as that's supposed to happen), but it saves to a Screenshot folder as well.

Tested in iOS 8 simulator, no screenshot folder.

Is this a iOS 9 issue? Library issue? WKWebView issue?

Thanks for any feedback.

Having downloaded the latest version of the library I'm seeing horrible performance even in the provided Demo App. In my own app I'm getting Memory Warnings regularly. while saving the image. What can be causing them? Attached are 2 profile logs, first of your demo app and second - of my own app implementing your library. Tested on the latest iOS 6 version on iPhone 4S.

Hi,

  Is there any method by which we can check that an image already exists in our folder?

Getting this error on iOS8

Error Domain=LIB_ALAssetsLibrary_CustomPhotoAlbum Code=0 "ALAssetsGroup failed to add asset: ALAsset - Type:Photo, URLs:assets-library://asset/asset.PNG?id=34FFE0D1-08BB-45DA-9C91-50D96F6158B9&ext=PNG."

As far as I can tell (I've stripped my code right down to test it so hopefully someone else can replicate the issue with different code), whenever you first save an image to the custom album, or move an existing image to the custom album the failure block fires. The image is saved, but only to the camera roll. The custom album is also created but is empty. Once the album has been created all images are saved or moved with no errors.

Add Photos.framework as Dependancy, because when it is not imported, application is unable to create new album. While it works perfectly when a same named album is already available in Photos App.

There are only two dependancies : https://github.com/Kjuly/ALAssetsLibrary-CustomPhotoAlbum#dependence

Completion block is called not in the main thread if the album didn't exist before the call.

The demo is very good!
Thank you very much.

Hello Dev,
I'm facing issue in load images method, where it's failure block doesn't work, when tries to search an unavailable or not created album or previously deleted album. Please Help.

Hi,
I could save my Captured image in Custom Photo Album, However along with it the image gets stored in camera roll, any method to remove images saved in camera roll or else can we restrict it from storing to Camera Roll.

Hi, i found out that the loadPhotosFromAlbum always return empty array. Anyway to fix it?

Hi,
Using the code previously hosted on touchcode it was possible to move an existing image to the custom album. With the github code it seems the public methods only allow saving to the custom album such that if the imagepicker selects an existing image from the camera roll (rather than a new one from the camera) it will resave the image into the custom album, creating a new copy.
Any chance of opening up the method to allow moving images to custom albums?

While I used this library flawlessly on my previous builds, iOS 8 has given me trouble as mentioned in a few other issues, yet I can't grasp it.

My question is posted here: https://stackoverflow.com/questions/27585750/alassetslibrary-customphotoalbum-ios-8

I am using the code mentioned in issue #2. But, when I try to save 17 images or so it works fine for some images and the process fails and gives following error:

_block_invoke238: Failed to add the asset to the custom photo album: Write busy

and only some images get save to the album. The problem is that the for loop is not waiting for the image to save or fail and it's firing multiple save requests... which overloads the writeImageToSavedPhotosAlbum method.

Why both completion and failure blocks take NSError parameters?

[assetsLibrary saveImageData:imageData toAlbum:@"Album" metadata:metadata 
completion:^(NSURL *assetURL, NSError *error) {
    // ...
} failure:^(NSError *error) {
    // ...
}];

Anyone know if the iOS 8.3 has become the problem of storing photos in album a deleted before?

I have this nserror:

EDIT: i modify the code with example and now i have this error:

only the first image saved when trying to save several photos using for loop

When calling the saveImageToAlbum( ), it is saving the photo in both the Camera Roll and the Album.

Is is possible to get a notification if the files in a particular album are changed.

• (void)assetForURL:(NSURL *)assetURL resultBlock:(ALAssetsLibraryAssetForURLResultBlock)resultBlock failureBlock:(ALAssetsLibraryAccessFailureBlock)failureBlock;

this function sometime return nil, which will lead the saveimage to failureblock.

if latest iOS 11.3 and 11.4 then not working this one framework , how to solve out this one problem. if iOS 11.0 below then working . save image and video custom folder then not create and not display photo library . how to solve out this one problem

This is a Pull Request in fact:
How to retrieve any image i want ? ( there is no such thing in README )

Hi,
Thanks for your reply. I want to save my images only to a particular folder. I don't want to save it in the camera roll. (just like Instagram is doing). I am using the following code to save images.

-(void)saveImage:(UIImage*)image toAlbum:(NSString*)albumName withCompletionBlock:(SaveImageCompletion)completionBlock
{
    //write the image data to the assets library (camera roll)
    [self writeImageToSavedPhotosAlbum:image.CGImage orientation:(ALAssetOrientation)image.imageOrientation 
                        completionBlock:^(NSURL* assetURL, NSError* error) {
                               //error handling
                          if (error!=nil) {
                              completionBlock(error);
                              return;
                          }
           //add the asset to the custom photo album
                          [self addAssetURL: assetURL 
                                    toAlbum:albumName 
                        withCompletionBlock:completionBlock];
                           }];
}

First, I call saveImage:toAlbum method and it work well, the "Ablum1' is created.

Second, I delete "Album1", and run the code again. I get this error in this method
_assetForURLResultBlockWithGroup

What's your suggestions？ Thanks!

See this link: http://stackoverflow.com/questions/26003211/assetslibrary-framework-broken-on-ios-8

I have successfully used your category in the past and was now attempting to use it with some iOS 8 code (including some Swift).

I ran across the error:
"Expected a type"
which referenced UIImage in the header file in the code:

• (void)saveImage:(UIImage *)image

I fixed this by adding the following to the header:
@import UIKit;

When i try to save photo to album with same name as a deleted album. New album can not be created.
Image is stilled added to library The album is just not created. No error is returned.

Hi @Kjuly I am using the latest version of your library but i am facing this issue on IOS 11: ALAssetsGroup failed to add asset: null.I am sure i added the Photos.framework to my Project.I run your ALAssetsLibraryCustomPhotoAlbum_BasicDemo in my iPhone6, and i am also facing this issue.Any help would be great.

Hi there, I'm using XCode 6.3 and Swift 1.2 and when runing the code:
ALAssetsLibrary().saveImage(screenshot, toAlbum: "myAlbum", completion:nil, failure:nil)

I get the error:

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[ALAssetsLibrary saveImage:toAlbum:completion:failure:]: unrecognized selector sent to instance

I use a bridging header to link the Objective C code with Swift

In the build phases I added the MobileCoreService and the AssetsLibrary framework

Any help would be much appreciated

The application Freezes when 100+ requests are send for writting. Upon faliour i am iterating the same method for writting. Here the code.

- (void)savingDownloadedImages : (UIImage *)img withDictionary:(NSDictionary*)dic {
    NSString *albumName     = dic[kPhotoAlbumName];

    ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
    [library saveImage:img toAlbum:albumName completion:^(NSURL *assetUrl, NSError *error) {
        if (error) {
            [self savingDownloadedImages:img withDictionary:dic];
        }
    } failure:^(NSError *error){
        [self savingDownloadedImages:img withDictionary:dic];
    }];
}

It seems that running with -com.apple.CoreData.ConcurrencyDebug 1 generates a crash when using saveVideo:toAlbum:completion: on iOS 8.3 and higher. I am still working through finding the exact issue but I suspect something related to PhotoKit.

The crash is [NSManagedObjectContext __Multithreading_Violation_AllThatIsLeftToUsIsHonor__] it is reproducible with both the device and simulator. Seems like it is trying to deallocate a batch request of some sort.

I will let you know if I determine the root cause. If anyone has seen this issue please let me know. This is debugging with Xcode 6.4

The method - (void)saveImage:(UIImage *)image toAlbum:(NSString *)albumName completion:(ALAssetsLibraryWriteImageCompletionBlock)completion failure (ALAssetsLibraryAccessFailureBlock)failure; doesn't save images to photos

In Xcode 6.1.1, the Analyzer reports the issue "Argument to 'NSString' method 'compare:' cannot be nil"
