位置服务iOS提醒回电

请任何人都可以告诉我如何捕获允许按钮点击并成功我想要我的代码.

实现这个:

- (void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status {
    if (status == kCLAuthorizationStatusAuthorizedAlways || status == kCLAuthorizationStatusAuthorizedWhenInUse) {
        //allowed - do your logic
    }
    else if (status == kCLAuthorizationStatusDenied) {
        //denied
    }
}

Swift 2.2:

self.locationManager.requestAlwaysAuthorization()

Swift 3.0:

func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
    switch status {
    case .notDetermined:
        manager.requestAlwaysAuthorization()
    case .restricted, .denied:
        // location services unauthorized
    case .authorizedAlways, .authorizedWhenInUse:
        manager.startUpdatingLocation()
    @unknown default:
        print("New CLLocationManager.authorizationStatus() not handled!")
    }    
}

记得设置你的代表:

self.locationManager.delegate = self;

并由您的班级实现: locationManager
