# RPSystemBroadcastPickerView

A view displaying a broadcast button that, when tapped, shows a broadcast picker.

```
class RPSystemBroadcastPickerView
```

## Overview

Add this view to your view hierarchy to let users broadcast directly from your app. When a user taps the broadcast button, it displays a broadcast picker, allowing the user to select a broadcast provider.

> Note:
> Clicking the broadcast button has no effect in Mac apps built with Mac Catalyst.

You can limit the picker to a particular broadcast provider by setting [`preferredExtension`](/documentation/ReplayKit/RPSystemBroadcastPickerView/preferredExtension) to the bundle identifier of a broadcast extension. You can also show or hide the microphone button displayed in the picker by setting the [`showsMicrophoneButton`](/documentation/ReplayKit/RPSystemBroadcastPickerView/showsMicrophoneButton) property. Set these properties before presenting [`RPSystemBroadcastPickerView`](/documentation/ReplayKit/RPSystemBroadcastPickerView), as shown here:

```swift
class ViewController: UIViewController {

    @IBOutlet var containerView: UIView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
     
        let broadcastPicker = RPSystemBroadcastPickerView(frame: CGRect(x: 0, y: 0, width: 50, height: 50))
        broadcastPicker.preferredExtension = "com.your-app.broadcast.extension"

        containerView.addSubview(broadcastPicker)
    }
    
}
```
