Kinvey iOS query all users

Question

From Kinvey documentation this is the method to use for querying users:

To query the user collection we recommend instead using +[KCSUserDiscovery lookupUsersForFieldsAndValues:completionBlock:progressBlock:]. This method allows you to supply a dictionary of exact matches for special fields.

Fields for lookup:

• KCSUserAttributeUsername
• KCSUserAttributeSurname
• KCSUserAttributeGivenname
• KCSUserAttributeEmail
• KCSUserAttributeFacebookId

 [KCSUserDiscovery lookupUsersForFieldsAndValues:@{ KCSUserAttributeSurname : @"Smith"}
                                    completionBlock:^(NSArray *objectsOrNil, NSError *errorOrNil) {
                                        if (errorOrNil == nil) {
                                            //array of matching KCSUser objects
                                            NSLog(@"Found %d Smiths", objectsOrNil.count);
                                        } else {
                                            NSLog(@"Got An error: %@", errorOrNil);
                                        }
                                    }
                                      progressBlock:nil];

But if I send empty dictionary, I get an error. So what to put in dictionary to get all the users?

Thank you guys, happy holidays

To get all the users, you can use the regular app data querying API.

For example,

KCSAppdataStore* store = [KCSAppdataStore storeWithCollection:[KCSCollection userCollection] options:nil];
[store queryWithQuery:[KCSQuery query] withCompletionBlock:^(NSArray *objectsOrNil, NSError *errorOrNil) {
    //handle completion
} withProgressBlock:nil];

This will get a list of all the users the active user has permission to access.
