Recording and streaming a live feed from your app can be difficult, especially if you want to reach a global audience with little to no latency. The Agora Voice and Video SDK is perfect for reliably sending low-latency messages to a global audience, where you can have one or more people streaming their feeds.To get more news about moonlive, you can visit official website.
In this tutorial, you learn how to create an application that enables users to be either a streamer or an audience member in a session. The setup is very similar to creating a video call with Agora, with a slight difference of roles: audience and broadcaster.

In this initial UIViewController, we can just have a button in the center to join the channel. This button will tell the application to open a view on top, enabling us to join as an audience member by default.
Next, create the ChannelViewController.swift file. This file will contain our UIViewController subclass called ChannelViewController, which displays the Agora pieces. In it, we will store values such as App ID, token, and channel name for connecting to the service, and add a button to change the user role between audience (default) and broadcaster. Also, initialise the Agora Engine with the correct client role. I have also preemptively added remoteUserIDs and userVideoLookup, which will keep track of the broadcasters/streamers.
When userVideoLookup is set or updated, reorganiseVideos is called to organise all of the streamed video feeds into a grid formation. Of course, a grid formation is not required, but if you want to implement the same thing, the reorganiseVideos method is provided in the example project. Here’s a link to it:
The hostButton has a target set as toggleBroadcast. This method is found right at the bottom of the gist. As you can see, it toggles the value of self.userRole between .broadcaster and .audience, and then sets the client role using setClientRole. When the local client starts streaming, additional buttons should appear (for audio and video settings). But those buttons are displayed only after the client role has been changed, which is signaled by the delegate callback.
When the user is streaming, they should have additional options, including the ability to switch between the device’s front- and back-facing cameras and turning the camera or microphone on and off. In this case, a beautification toggle is added. To show and hide these options, the isHidden property of the button container is set to false or true, respectively.
