How can Objective C apps handle push notifications and background tasks?
Objective C apps can handle push notifications and background tasks using various techniques and APIs provided by the iOS platform. The main components involved in handling these functionalities are the AppDelegate class, the UserNotifications framework, and the background execution modes. By utilizing these resources, developers can implement the necessary code to receive and handle push notifications, as well as perform tasks in the background. Additionally, configuring the appropriate permissions and registering for remote notifications is crucial for receiving push notifications. Background tasks can be initiated based on specific triggers such as location changes, network availability, or set time intervals.
