im trying to present a list of all the albums titles in my iphone and when i press a title i want it to present all the photos of that specific album in a collection view.I am using the "PhotosUI" framework and i use this code to get the album titles:
-(void)getLibrariesList
{
NSArray *collectionsFetchResults;
albumNames = [[NSMutableArray alloc] init];
PHFetchResult *smartAlbums = [PHAssetCollection fetchAssetCollectionsWithType:PHAssetCollectionTypeSmartAlbum
subtype:PHAssetCollectionSubtypeAlbumRegular options:nil];
PHFetchResult *syncedAlbums = [PHAssetCollection fetchAssetCollectionsWithType:PHAssetCollectionTypeAlbum
subtype:PHAssetCollectionSubtypeAlbumSyncedAlbum options:nil];
PHFetchResult *userCollections = [PHCollectionList fetchTopLevelUserCollectionsWithOptions:nil];
PHFetchOptions *userAlbumsOptions = [PHFetchOptions new];
userAlbumsOptions.predicate = [NSPredicate predicateWithFormat:@"estimatedAssetCount > 0"];
// Add each PHFetchResult to the array
collectionsFetchResults = @[smartAlbums, userCollections, syncedAlbums];
for (int i = 0; i < collectionsFetchResults.count; i ++) {
PHFetchResult *fetchResult = collectionsFetchResults[i];
for (int x = 0; x < fetchResult.count; x ++) {
PHCollection *collection = fetchResult[x];
albumNames[x] = collection.localizedTitle;
}
}
//update the tableview
[self.libraryTableView reloadData];
}
and this code to get all the photos for the specific album by it's title:
-(void)showPhotosInCollectionViewForALbumWithName:(NSString*)albumName
{
libraryAssets = [NSMutableArray array];
__block PHAssetCollection *collection;
// Find the album
PHFetchOptions *fetchOptions = [[PHFetchOptions alloc] init];
fetchOptions.predicate = [NSPredicate predicateWithFormat:@"title = %@", albumName];
collection = [PHAssetCollection fetchAssetCollectionsWithType:PHAssetCollectionTypeAlbum
subtype:PHAssetCollectionSubtypeAny
options:fetchOptions].firstObject;
PHFetchResult *collectionResult = [PHAsset fetchAssetsInAssetCollection:collection options:nil];
[collectionResult enumerateObjectsUsingBlock:^(PHAsset *asset, NSUInteger idx, BOOL *stop) {
[libraryAssets addObject:asset];
}];
[self.libraryPhotosCollectoionView reloadData];
}
for certain albums it's working, albums like "Instagram" and albums i have created with my phone but when i press the "Camera Roll" and "My Photo Stream" album it dosent show anything.
any ideas why this is happening or if there another way to fetch all of my device's photos?
