How to detect when RPSystemBroadcastPickerView is dismissed?

Question

In the app, I am using a RPSystemBroadcastPickerView to start a system-wide screen recording. I need to react to the user starting screen record or dismissing the shown picker view. In both cases, the system view gets dismissed.

I assumed that dismissing the system picker view will trigger a viewDidAppear event on the currently shown view controller. This does not happen. I tried to test if the AppDelegate triggers applicationDidBecomeActive or applicationWillEnterForeground - again without success (this are triggered when user open control center).

Does anyone have a suggestion what else to try?

@McDonal_11 the `RPSystemBroadcastPickerView` will show a pop up to stop it, when tapped again.. — Milan Nosáľ, Mar 27 '19 at 11:53
yes. But, with out that pop up or with out pressing that top red bar, simply by button action to stop record ?? — McDonal_11, Mar 27 '19 at 12:21
@McDonal_11 you can use this workaround https://stackoverflow.com/a/52804040/2912282 to show the pop up yourself.. — Milan Nosáľ, Mar 27 '19 at 12:22
yes, I have tried urs already. It showing that pop up view, in button action. I understood this well. I having separate button for STOP. I don't know to stop record. — McDonal_11, Mar 27 '19 at 12:26
@McDonal_11 User has to stop recording, you cannot do that directly without prompting user. — Milan Nosáľ, Mar 27 '19 at 12:30
yes. User has to stop . But, I am giving button action to user to stop record. But I don't know, how to do that. — McDonal_11, Mar 27 '19 at 12:35
@McDonal_11 A I have already said, the ONLY way the recording can be stopped, is through the pop up. You have to show the user the pop up and the user has to stop it through there. — Milan Nosáľ, Mar 27 '19 at 12:36

Before iOS 13: hook RPSystemBroadcastPickerView containerVC

iOS 14.0 or later: Monitor the focus and out-focus events of the app

I would add the reasoning why these plist values would be applicable in this case. – Justicle Jul 11 '23 at 18:42

You can achieve it indirectly using Timer and UserDefaults.

Start the Timer in ViewController from the main app and check for corresponding value change from Broadcast Extension.

 class SampleHandler: RPBroadcastSampleHandler {

    override func broadcastStarted(withSetupInfo setupInfo: [String : NSObject]?) {
       appGroupDefaults.set(true, forKey: appGroupUserDefaultKeys.isScreenBroadcastStarted.rawValue)
    }

    override func broadcastFinished() {
       appGroupDefaults.set(true, forKey: appGroupUserDefaultKeys.isScreenBroadcastStopped.rawValue)
    }
    
 }

using timer is bad ideal – famfamfam Oct 09 '21 at 07:53
I'll never use this solution no matter how desperate I'm. – Jaswant Singh Jul 26 '22 at 10:35
