# locationManager(_:didDetermineState:for:)

Tells the delegate about the state of the specified region.

## Declaration

```swift
optional func locationManager(_ manager: CLLocationManager, didDetermineState state: CLRegionState, for region: CLRegion)
```

## Parameters

- `manager`: The location manager object reporting the event.
- `state`: The state of the specified region. For a list of possible values, see the doc://com.apple.corelocation/documentation/CoreLocation/CLRegionState type.
- `region`: The region whose state was determined.

## Discussion

Discussion The location manager calls this method whenever there is a boundary transition for a region. It calls this method in addition to calling the  locationManager(_:didEnterRegion:) and locationManager(_:didExitRegion:) methods. The location manager also calls this method in response to a call to its requestState(for:) method, which runs asynchronously.
