AFRocketClient

Rocket is a technique for building real-time functionality on top of REST web services that leverages web standards like Server-Sent Events and JSON Patch.

AFEventSource is an Objective-C implementation of the EventSource DOM API. A persistent HTTP connection is opened to a host, which streams events to the event source, to be dispatched to listeners. Messages streamed to the event source formatted as JSON Patch documents are translated into arrays of AFJSONPatchOperation objects. These patch operations can be applied to the persistent data set fetched from the server.

Rocket Example

NSURL *URL = [NSURL URLWithString:@"http://example.com"];
AFRocketClient *client = [[AFRocketClient alloc] init];
[client SUBSCRIBE:@"/resources" usingBlock:^(NSArray *operations, NSError *error) {
    for (AFJSONPatchOperation *operation in operations) {
        switch (operation.type) {
            case AFJSONAddOperationType:
                [resources addObject:operation.value];
                break;
            default:
                break;
        }
    }
} error:nil]
