ALAssetsLibrary get Camera Roll - ios

Question

I enumerate all assets groups using ALAssetsLibrary
Here is code:
ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
void (^enumerate)(ALAssetsGroup *, BOOL *) = ^(ALAssetsGroup *group, BOOL *stop)
{
if (group == nil)
{
// enumerated all albums..
}
// I hot to check if group is Camera Roll ?
};
[library enumerateGroupsWithTypes:ALAssetsGroupAll
usingBlock:enumerate
failureBlock:nil];
How to check if some current enumerated is CameraRoll?
Edit: As i tested it was always the last, using this enumerating. But i am not sure if it is the rule, are there any references that i missed?

Answer 1

To get photos from camera roll use ALAssetsGroupSavedPhotos while enumerating assets library:
[library enumerateGroupsWithTypes:ALAssetsGroupSavedPhotos
usingBlock:enumerate
failureBlock:nil];
To detect what group you currently get:
if ([[group valueForProperty:#"ALAssetsGroupPropertyType"] intValue] == ALAssetsGroupSavedPhotos)
{
NSLog(#"Camera roll");
}

Answer 2

imageArray = [[NSArray alloc] init];
NSMutableArray*mutableArray =[[NSMutableArray alloc]init];
NSMutableArray* assetURLDictionaries = [[NSMutableArray alloc] init];
ALAssetsLibrary*library = [[ALAssetsLibrary alloc] init];
void (^enumerate)(ALAssetsGroup *, BOOL *) = ^(ALAssetsGroup *group, BOOL *stop)
{
if ([[group valueForProperty:#"ALAssetsGroupPropertyType"] intValue] == ALAssetsGroupSavedPhotos)
{
NSLog(#"Camera roll");
[group enumerateAssetsUsingBlock:^(ALAsset *result, NSUInteger index, BOOL *stop) {
ALAssetRepresentation *rep = [result defaultRepresentation];
NSLog(#"Asset Name ----> %#",rep.filename);
}];
}
// I hot to check if group is Camera Roll ?
};
[library enumerateGroupsWithTypes:ALAssetsGroupSavedPhotos
usingBlock:enumerate
failureBlock:nil];
