Notes WWDC 2021 : Meet the Location Button

#dev #iOS

Mes notes pour la session Meet the Location Button de la WWDC 2021.

CLLoctionButton: new way to request location authorization.

Gives the app “allow once” authorization without prompt.

Customizable, but with restrictions: will log a message for “inappropriate size”, “insufficient alpha” or “insufficient contrast ratio between tintColor and backgroundColor”.

let button = CLLocationButton()
button.label = .currentLocation
button.addTarget(self, action: #selector(showParks), for: .touchUpInside)

// ...

@objc func showParks() {
  // Not needed, called by the button itself
  // self.locationManager.requestWhenInUseAuthorization()

For SwiftUI, use LocationButton()
