I am using the Photos framework to fetch album list in iOS8. I am able to do it using
PHFetchResult *smartAlbums = [PHAssetCollection fetchAssetCollectionsWithType:PHAssetCollectionTypeSmartAlbum subtype:PHAssetCollectionSubtypeAlbumRegular options:nil];
This gives me a list of all smart albums including videos. How can I filter out videos from this list. I need only images.
Help would be appreciated. Thanks.
You should set up fetch options, its has a property predicate
, which can be used to filter videos. Below is an example of doing that.
PHFetchResult *smartAlbums = [PHAssetCollection fetchAssetCollectionsWithType:PHAssetCollectionTypeSmartAlbum subtype:PHAssetCollectionSubtypeAlbumRegular options:nil];
//set up fetch options, mediaType is image.
PHFetchOptions *options = [[PHFetchOptions alloc] init];
options.sortDescriptors = @[[NSSortDescriptor sortDescriptorWithKey:@"creationDate" ascending:NO]];
options.predicate = [NSPredicate predicateWithFormat:@"mediaType = %d",PHAssetMediaTypeImage];
for (NSInteger i =0; i < smartAlbums.count; i++) {
PHAssetCollection *assetCollection = smartAlbums[i];
PHFetchResult *assetsFetchResult = [PHAsset fetchAssetsInAssetCollection:assetCollection options:options];
NSLog(@"sub album title is %@, count is %ld", assetCollection.localizedTitle, assetsFetchResult.count);
if (assetsFetchResult.count > 0) {
for (PHAsset *asset in assetsFetchResult) {
//you have got your image type asset.
}
}
}
