My code was working on OS 4.3 but with 5 i am getting warnings regarding ALAssetsGroup for the ALAssetsGroup i dont get any methods for it so i get instance not found for the enumerate see code
void (^assetEnumerator)(ALAsset *, NSUInteger, BOOL *) = ^(ALAsset *result, NSUInteger index, BOOL *stop)
{
if(result != nil)
{
[assets addObject:result];
}
};
// Create instance of the Assets Library.
void (^assetGroupEnumerator)( ALAssetsGroup *, BOOL *) = ^(ALAssetsGroup *group, BOOL *stop) {
if(group != nil)
{
[group enumerateAssetsUsingBlock:assetEnumerator];
}
};
assets = [[NSMutableArray alloc] init];
ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
[library enumerateGroupsWithTypes:ALAssetsGroupAlbum
usingBlock:assetGroupEnumerator
failureBlock: ^(NSError *error) {
NSLog(@"failureBlock:%@",error);
}];
Any help will be appreciated Thanks

as of iOS 5 more Assets-Library methods are asynchronous and want to be called from the main-thread. Make sure you call your 2nd block enumerating the group from the main-thread using dispatch_async on the main-queue.
