Ios App Launched In Background

You can use this difference to adjust the launch time behavior of your delegate methods accordingly.

Ios app launched in background. The app switcher is an important control feature introduced in ios 7. If an app allows you to make data based phone calls like whatsapp or skype calls in the background it can stay active using cpu for the duration of the call. Apps move to the background state for many reasons.

When the user exits a foreground app that app moves to the background state briefly before uikit suspends it. Tapping an application launches it into the foreground. If an app plays audio in the background over airplay or through the phone s speakers ios permits it to run in the background until it ceases to play the music.

When the app is launched into the background the property contains the value uiapplicationstatebackground instead. Using the app switcher users can scroll through snapshots of all backgrounded and suspended applications. The system may also launch an app directly into the background state or move a suspended app into the background and give it time to perform important tasks.

The app uses region monitoring so it will be launched by the system into background automatically when user leaves a region that the app previously registered to monitor even when the app is not running with always location permission.
