Question

I need to use the assets library: i’ve found a snippets like this:

[library enumerateGroupsWithTypes:ALAssetsGroupAlbum
                        usingBlock:assetGroupEnumerator
                        failureBlock: ^(NSError *error) {
                            NSLog(@"Failure");
                        }];

and the compiler gives me the error like doesn’t recognize the block ^.

is there a setting or something to enable the blocks in the project?
thanks in advance

here is the complete error / code:

My original answer — Looks like you need to add the AssetsLibrary framework to your project.

My new answer — for your asset enumerations, get rid of the “struct” keyword in your block declarations. You don’t need them.

e.g.

void (^assetGroupEnumerator)(ALAssetsGroup *, BOOL *) = ^(ALAssetsGroup *group, BOOL *stop){

and

void (^assetEnumerator)(ALAsset *, NSUInteger, BOOL *) = ^(ALAsset * result, NSUInteger index, BOOL * stop)
