Answer 1

You can use IOSNotification

iOS specific notification settings.

NOTE: Some of these settings apply only to iOS 9, or iOS 10+. These are flagged as appropriate.

launchImage returns nullable string;

Gets the launch image to use with the notification.

setLaunchImage(launchImage) returns Notification;

Sets the launch image for the notification.

launchImage : string

Example

notification
  .ios.setLaunchImage('notificationimage.png');
