API Cheat Sheet

Code Examples
The demo projects on Github contain some useful code examples. 
​Android Code Examples 1​

Configuration
The Chat SDK can be configured using the configuration service. 
Java
Swift
Objective C
1
Config config = ChatSDK.config();
2
​
3
// Example
4
config.setGoogleMaps("Google Maps API Key");
Copied!
1
let config: BConfiguration = BChatSDK.config()
2
​
3
// Example
4
config.googleMapsApiKey = "Google Maps API Key"
Copied!
1
BConfiguration * config = BChatSDK.config;
2
​
3
// Example
4
config.googleMapsApiKey = @"Google Maps API Key";

Messaging Server API
The Chat SDK uses a series of services to make requests to the messaging server. These services are contained in a class called NetworkAdapter.   
Java
Swift
Objective C
1
BaseNetworkAdapter a = ChatSDK.shared().a();
Copied!
1
let networkAdapter = BChatSDK.shared()?.networkAdapter
Copied!
1
id<PNetworkAdapter> networkAdapter = BChatSDK.shared.networkAdapter;
Copied!
Each of these services contains methods to make requests to the server. Here is a full list of the services available:
Java

Messaging Server Notifications
Since messaging happens in realtime, we also need to get notifications from the server. This happens through several mechanisms. For more details see:
​Events In Android​
Some available for Android and others for iOS:
1. Event Bus (Android)
Java
EventType.java
1
Predicate<NetworkEvent> filter = NetworkEvent.filterType(EventType.MessageAdded, EventType.MessageRemoved);
2
​
3
Disposable d = ChatSDK.events()
4
        .source()
5
        .filter(filter)
6
        .subscribe(networkEvent -> {
7
​
8
            // Handle Event Here
9
            if (networkEvent.getMessage() != null) {
10
                Logger.debug(networkEvent.getMessage().getText());
11
            }
12
    
13
        });

UI Modification Service
Chat SDK provides a way to modify the user interface without forking the library. This can be achieved using the UI server. 
Java
Swift
Objective C
1
InterfaceAdapter interfaceAdapter = ChatSDK.ui();
Copied!
1
let interfaceAdapter: PInterfaceAdapter = BChatSDK.ui()
Copied!
1
id<PInterfaceAdapter> interfaceAdapter = BChatSDK.ui;
Copied!
The UI service is used to inject views into the app. It also defines which tabs are displayed and much more.  For example, you can override Activites, Fragments, and ViewControllers by subclassing them and injecting them using the UI service. 
Java
Swift
Objective C
1
// Override an activity
2
ChatSDK.ui().setChatActivity(CustomChatActivity.class);
3
​
4
// Override a fragment
5
ChatSDK.ui().setProfileFragmentProvider(user -> {
6
    ProfileFragment fragment =  new AProfileFragment();
7
    fragment.setUser(user);
8
    return fragment;
9
});
Copied!
1
// Override the chat view controller
2
BChatSDK.ui().setChatViewController({ thread -> UIViewController in
3
    return AChatViewController.init(thread: thread)
4
})
5
​
6
// Override the private threads tab
7
BChatSDK.ui().setPrivateThreadsViewController(APrivateThreadsViewController.init(nibName: nil, bundle: nil))
8
​
Copied!
1
// Override the chat view controller
2
[BChatSDK.ui setChatViewController: ^UIViewController *(id<PThread> thread) {
3
    return [[AChatViewController alloc] initWithThread:thread];
4
}];
5
​
6
// Override the private threads tab
7
[BChatSDK.ui setPrivateThreadsViewController:[[APrivateThreadsViewController alloc] initWithNibName:nil bundle:nil]];

Local Database
The Chat SDK has a powerful local database that is automatically synchronized with the messaging server. It can be accessed using the database service. 
Java
Swift
Objective C
1
StorageManager storageManager = ChatSDK.db();
Copied!
1
let storageAdapter: PStorageAdapter = BChatSDK.db()
Copied!
1
id<PStorageAdapter> storageAdapter = BChatSDK.db;
Copied!
The database service can be used to fetch, create, and delete entities. For example:
Java
Swift
Objective C
1
// Create entity
2
User user = ChatSDK.db().createEntity(User.class);
3
​
4
// Fetch an entity with a given ID
5
Thread thread = ChatSDK.db().fetchEntityWithEntityID("threadEntityID", Thread.class);
6
​
7
// Fetch or create an entity with a given ID
8
User otherUser = ChatSDK.db().fetchOrCreateEntityWithEntityID(User.class, "userEntityID'");
Copied!
1
// Create entity
2
if let user: PUser = BChatSDK.db().createEntity(bUserEntity) as? PUser {
3
    
4
}
5
​
6
// Fetch an entity with a given ID
7
if let thread: PThread? = BChatSDK.db().fetchEntity(withID: "threadEntityID", withType: bThreadEntity) as? PThread {
8
    
9
}
10
​
11
// Fetch or create an entity with a given ID
12
if let otherUser: PUser = BChatSDK.db().fetchOrCreateEntity(withID: "userEntityID", withType: bUserEntity) as? PUser {
13
    
14
}
Copied!
1
// Create entity
2
id<PUser> user = [BChatSDK.db createEntity:bUserEntity];
3
​
4
// Fetch an entity with a given ID
5
id<PThread> thread = [BChatSDK.db fetchEntityWithID:@"threadEntityID" withType:bThreadEntity];
6
​
7
// Fetch or create an entity with a given ID
8
id<PUser> otherUser = [BChatSDK.db fetchOrCreateEntityWithID:@"userEntityID" withType:bUserEntity];
9
​
Copied!
Each entity then has many methods that can be used. For example:
Java
Swift
Objective C
1
user.setName("Test");
2
user.setAvatarURL("http://something.png");
3
​
4
List<User> users = thread.getUsers();
5
List<Message> messages = thread.getMessages();
6
​
7
// etc...
Copied!
1
user.setName("test");
2
user.setImageURL("http://something.png")
3
​
4
let users = thread?.users()
5
let messages = thread?.messagesOrderedByDateNewestFirst()
6
​
7
// etc...
Copied!
1
[user setName:@"Test"];
2
[user setImageURL:@"http://something.png"];
3
​
4
NSArray * users = thread.users;
5
NSArray * messages = thread.messagesOrderedByDateNewestFirst;
6
​
7
// etc...
8
​
Copied!
Note: Creating an entity locally doesn't automatically add it to the server or populate the data from the server. To do that you have to use the network adapter service.
