FirebaseObjects is a repo with a few classes to make common firebase tasks easier.

FirebaseCollection: Keep a Dictionary in sync with a firebase

// somewhere in viewDidLoad
self.firebase = [[Firebase alloc] initWithUrl:@"https://fake.firebaseio.com/stuff"];
self.dictionary = [NSMutableDictionary dictionary];
self.collection = [[FirebaseCollection alloc] initWithNode:firebase dictionary:dictionary type:[User class]];

[self.collection didAddChild:^(User * user) {
    // created remotely or locally, it is called here
    NSLog(@"New User %@", user);
    [self.tableView reloadData];
}];

User * me = [User new];
me.name = @"me";
[self.collection addObject:me];

What if I want to run a table view?

Just use the dictionary's allValues to drive it.

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return [self.dictionary.allValues count];
}

Initialization on object types

Tell the collection what type your objects should be by passing in the class. Alternatively, you can use the factory init method to create one with a block

self.collection = [[FirebaseCollection alloc] initWithNode:firebase dictionary:dictionary factory:^(NSDictionary* value) {
    return [User new];
}];

Firebase calls setValuesForKeysWithDictionary internally to set values on your object. So

Implement Objectable

Your class (User in this example) should implement the Objectable protocol so FirebaseCollection knows how to convert it into a dictionary.

-(NSDictionary*)toObject {
    return [self dictionaryWithValuesForKeys:@[@"name"]];
}

Adding, Removing and Updating all handled for you

Use didAddChild, didRemoveChild and didUpdateChild to be notified when they have been changed

FirebaseConnection: be notified when connection changes

self.connection = [[FirebaseConnection alloc] initWithFirebaseName:@"myfirebasename" onConnect:^{
    [self connectToLobby];
} onDisconnect:^{
    [self showDiconnectedScreen];
}];
