Minimize video call window
With only two simple steps, you can achieve the effect of minimizing the video call window within the application.
Ideally, the final effect will look like this:
Integrate the minimize function into the app
Prepare the environment
- iOS 16.0 or higher version and iOS devices that support audio and video.
Display the minimize button
To display the minimize button, configure the ZegoUIKitPrebuiltCallConfig's topMenuBarConfig or bottomMenuBarConfig, and add the ZegoMenuBarButtonName.minimizingButton to bottomMenuBarConfig.buttons or topMenuBarConfig.buttons to show a minimize button.
Here is the sample code:
//....
ZegoUIKitPrebuiltCallInvitationService.shared.delegate = self
//...
func requireConfig(_ data: ZegoCallInvitationData) -> ZegoUIKitPrebuiltCallConfig {
if data.type == .voiceCall {
if data.invitees?.count ?? 0 > 1 {
let config = ZegoUIKitPrebuiltCallConfig.groupVoiceCall()
config.topMenuBarConfig.isVisible = true
config.topMenuBarConfig.buttons = [.minimizingButton]
return config
} else {
let config = ZegoUIKitPrebuiltCallConfig.oneOnOneVoiceCall()
config.topMenuBarConfig.isVisible = true
config.topMenuBarConfig.buttons = [.minimizingButton]
return config
}
} else {
if data.invitees?.count ?? 0 > 1 {
let config = ZegoUIKitPrebuiltCallConfig.groupVideoCall()
config.topMenuBarConfig.isVisible = true
config.topMenuBarConfig.buttons = [.minimizingButton]
return config
} else {
let config = ZegoUIKitPrebuiltCallConfig.oneOnOneVideoCall()
config.topMenuBarConfig.isVisible = true
config.topMenuBarConfig.buttons = [.minimizingButton]
return config
}
}
}
// ...After completing the above steps, you can now minimize the video call window.
FAQ
When the minimizingButton is added and the iOS system version is higher than 15, the mini video will be displayed when the mini video button is clicked again or when switching to the home screen. When the mini video is clicked, it will return to the call page. If your system version is less than 15, the mini video will not be displayed.
Apple restricts background camera access to protect user privacy and manage device resources. The permission to access the camera in the background cannot be obtained through any form of application. When an app goes into the background, iOS automatically revokes camera access to prevent unintended or malicious data collection.
Apple's strong commitment to user privacy means no form of application can grant background camera access. When an app is in the background, iOS pauses or stops camera access. We must pause camera-related functions when an app is in the background and resume them in the foreground.
Bypassing these protective measures can lead to your app's rejection or removal from the App Store.
Apple's guide on background execution discusses the behavior of iOS apps in the background, but doesn't include background camera access due to privacy concerns. Here's the guide: BackgroundExecution.
Ensure your app respects user privacy and follows all of Apple's guidelines and policies.
