Millised piirangud on tausteseisundi kontekstis süsteemides või rakendustes?

In background mode, iOS applications operate with restrictions related to resources and execution time:

• The application is not displayed on the screen and can be suspended by the system to save resources.
• The execution time of background tasks is limited (usually a few seconds), unless special background modes are used.
• Background tasks should be short and efficient; otherwise, the system may terminate the application.
• For long-running background operations, Background Modes should be used (e.g., audio, location, file uploads).
• Access to certain resources, such as UI elements, is restricted.

Therefore, developers should carefully plan background work to avoid violating platform rules and to ensure good performance.
