RabbitMQ Obj-C client connection status check

问题

I'm using rabbitmq/rabbitmq-objc-client. Is there a way how to check if connection was opened successfully? I see there is RMQConnectionDelegate but there are only methods that are called when an error appears. I'm looking for something like

RMQConnection *conn = [[RMQConnection alloc] /*...*/];
if ([conn isOpen]) {
    /* ... */
}

回答1:

You can do this:

[conn start:^{ // code to execute when connection established }];

But note that the client is async and all channel operations are placed onto a queue for execution after the connection is established.

I've added a note to the issue Michael opened: https://github.com/rabbitmq/rabbitmq-objc-client/issues/101
