ALAssetsLibrary addAssetsGroupAlbumWithName is not working on iOS 9 - ios

Question

I need to add group with name "MyGroupName" in ALAssetsLibrary . So I have used below code.
ALAssetsLibrary * library = [[ALAssetsLibrary alloc] init];
__weak ALAssetsLibrary *lib = library;
[library addAssetsGroupAlbumWithName:#"MyGroupName" resultBlock:^(ALAssetsGroup *group) {
[lib enumerateGroupsWithTypes:ALAssetsGroupAlbum
usingBlock:^(ALAssetsGroup *g, BOOL *stop)
{
if ([[g valueForProperty:ALAssetsGroupPropertyName] isEqualToString:#"MyGroupName"]) {
NSLog(#"group created with name 'MyGroupName'");
}
}failureBlock:^(NSError *error){
NSLog(#"failure %#",error);
}
];
} failureBlock:^(NSError *error) {
NSLog(#"failure %#",error);
}];
but inside "enumerateGroupsWithTypes" , group "g" is always nil in iOS 9.3.1 (iphone 6). its working correctly and group created with name "MyGroupName" on iOS 9.3.1 iphone 5. I want to know why above code is not working on iphone 6 and is there any solution to make it work ?
Please help me. Thanks in advance

Answer 1

1) First Import
#import <Photos/Photos.h>
#import <Photos/PHAsset.h>
#import <AssetsLibrary/AssetsLibrary.h>
2) Set property for ALAsset
#property (nonatomic, strong) ALAssetsLibrary* assetsLibrary;
3) Then allocate ALAsset library in your .m file
- (ALAssetsLibrary*)assetsLibrary
{
if (!_assetsLibrary) {
_assetsLibrary = [[ALAssetsLibrary alloc] init];
[ALAssetsLibrary disableSharedPhotoStreamsSupport];
}
return _assetsLibrary;
}
4 ) Now create method for save image to custom album
- (void)saveImageDatas:(UIImage*)imageDatas toAlbum:(NSString*)album withCompletionBlock:(void(^)(NSError *error))block
{
` if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0) {
[[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{
NSMutableArray* assets = [[NSMutableArray alloc]init];
PHAssetChangeRequest* assetRequest;
#autoreleasepool {
assetRequest = [PHAssetChangeRequest creationRequestForAssetFromImage:imageDatas];
[assets addObject:assetRequest.placeholderForCreatedAsset];
}
__block PHAssetCollectionChangeRequest* assetCollectionRequest = nil;
PHFetchResult* result = [PHAssetCollection fetchAssetCollectionsWithType:PHAssetCollectionTypeAlbum subtype:PHAssetCollectionSubtypeAlbumRegular options:nil];
[result enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
PHAssetCollection* collection = (PHAssetCollection*)obj;
if ([collection isKindOfClass:[PHAssetCollection class]]) {
if ([[collection localizedTitle] isEqualToString:album]) {
assetCollectionRequest = [PHAssetCollectionChangeRequest changeRequestForAssetCollection:collection];
[assetCollectionRequest addAssets:assets];
*stop = YES;
}
}
}];
if (assetCollectionRequest == nil) {
assetCollectionRequest = [PHAssetCollectionChangeRequest creationRequestForAssetCollectionWithTitle:album];
[assetCollectionRequest addAssets:assets];
}
}
completionHandler:^(BOOL success, NSError *error) {
if (block) {
block(error);
}
}];
}
else {
__weak ALAssetsLibrary* lib = [self assetsLibrary];
[[self assetsLibrary] writeImageDataToSavedPhotosAlbum:UIImageJPEGRepresentation(imageDatas, 1.0) metadata:nil completionBlock:^(NSURL* assetURL, NSError* error) {
if (error != nil) {
return;
}
__block BOOL albumWasFound = NO;
[lib enumerateGroupsWithTypes:ALAssetsGroupAlbum usingBlock:^(ALAssetsGroup* group, BOOL* stop) {
if ([[group valueForProperty:ALAssetsGroupPropertyName] isEqualToString:album]) {
albumWasFound = YES;
[lib assetForURL:assetURL resultBlock:^(ALAsset* asset){
[group addAsset:asset];
if (block) {
block(nil);
}
}failureBlock:^(NSError* error) {
if (block) {
block(error);
}
}];
return;
}
if (group == nil && albumWasFound == NO) {
[lib addAssetsGroupAlbumWithName:album resultBlock:^(ALAssetsGroup* group) {
} failureBlock:^(NSError* error) {
[lib assetForURL:assetURL resultBlock:^(ALAsset* asset){
[group addAsset:asset];
if (block) {
block(nil);
}
}failureBlock:^(NSError* error) {
if (block) {
block(error);
}
}];
}];
}
} failureBlock:^(NSError* error) {
if (block) {
block(error);
}
}];
}];
}
}
5 ) Now call this method to save the image like
[self saveImageDatas:myimage toAlbum:#"MyGroupName" withCompletionBlock:^(NSError *error) {
if (!error) {
NSLog(#"Sucess");
}
}];
"myimage" is your image that you want to save.

Answer 2

Please try this on:
ALAssetsLibrary* libraryFolder = [[ALAssetsLibrary alloc] init];
[libraryFolder addAssetsGroupAlbumWithName:#"My Album" resultBlock:^(ALAssetsGroup *group)
{
NSLog(#"Adding Folder:'My Album', success: %s", group.editable ? "Success" : "Already created: Not Success");
} failureBlock:^(NSError *error)
{
NSLog(#"Error: Adding on Folder");
}];
