Get all Users on OS X

Question

So I want to implement Parental Controls per user in my app, but I need a way of getting all Users and add them to an NSTableView. These users should be the same displayed b

Answer 1

Here's how I do it:

#import 
#import 

CSIdentityAuthorityRef defaultAuthority = CSGetLocalIdentityAuthority();
CSIdentityClass identityClass = kCSIdentityClassUser;

CSIdentityQueryRef query = CSIdentityQueryCreate(NULL, identityClass, defaultAuthority);

CFErrorRef error = NULL;
CSIdentityQueryExecute(query, 0, &error);

CFArrayRef results = CSIdentityQueryCopyResults(query);

int numResults = CFArrayGetCount(results);

NSMutableArray * users = [NSMutableArray array];
for (int i = 0; i < numResults; ++i) {
    CSIdentityRef identity = (CSIdentityRef)CFArrayGetValueAtIndex(results, i);

    CBIdentity * identityObject = [CBIdentity identityWithCSIdentity:identity];
    [users addObject:identityObject];
}

CFRelease(results);
CFRelease(query);

//users contains a list of known Aqua-style users.

The CBIdentity objects are much more convenient to use than the CSIdentityRef objects, but they do require importing the Collaboration framework.
