# requestTemporaryFullAccuracyAuthorization(withPurposeKey:)

Requests permission to temporarily use location services with full accuracy.

```
func requestTemporaryFullAccuracyAuthorization(withPurposeKey purposeKey: String)
```

## Parameters

`purposeKey`

A key in the <doc://com.apple.documentation/documentation/BundleResources/Information-Property-List/NSLocationTemporaryUsageDescriptionDictionary> dictionary of the app’s `Info.plist` file.  The value for this key is an app-provided string that describes the reason for accessing location data with full accuracy.  To localize a usage description, add an entry to your `InfoPlist.strings` file with the same key you provide for this parameter.

## Discussion

This method behaves the same as calling the [`requestTemporaryFullAccuracyAuthorization(withPurposeKey:completion:)`](/documentation/CoreLocation/CLLocationManager/requestTemporaryFullAccuracyAuthorization(withPurposeKey:completion:)) method, passing `nil` as the completion closure. Use this method if your app’s logic to respond to changes in location data accuracy is already handled by the [`locationManagerDidChangeAuthorization(_:)`](/documentation/CoreLocation/CLLocationManagerDelegate/locationManagerDidChangeAuthorization(_:)) delegate method, and your app doesn’t have any work to do in the closure.
