我正在尝试定位服务应用程序,因此当用户转到该视图控制器时,他将获得获取当前位置的警报。如何知道用户是否拒绝了Swift 2中的定位服务
这是代码
override func viewDidLoad() {
super.viewDidLoad()
// 1. status is not determined
if CLLocationManager.authorizationStatus() == .NotDetermined {
locationManager.requestAlwaysAuthorization()
}
// 2. authorization were denied
else if CLLocationManager.authorizationStatus() == .Denied {
SwiftSpinner.hide()
let alert = UIAlertController(title: "Error with Your Location" , message: "Location services were previously denied. Please enable location services for this app in Settings.", preferredStyle: UIAlertControllerStyle.Alert)
let ok = UIAlertAction(title: "OK", style: UIAlertActionStyle.Default) {
UIAlertAction in
UIApplication.sharedApplication().openURL(NSURL(string: UIApplicationOpenSettingsURLString)!)
}
alert.addAction(ok)
let cancel = UIAlertAction(title: "Back", style: UIAlertActionStyle.Default) {
UIAlertAction in
self.movenav("arxiki")
}
alert.addAction(cancel)
self.presentViewController(alert, animated: true, completion: nil)
}
// 3. we do have authorization
else if CLLocationManager.authorizationStatus() == .AuthorizedAlways {
locationManager.startUpdatingLocation()
}
self.navigationController?.setNavigationBarHidden(false, animated: true)
self.eventsTable.backgroundColor = UIColor.lightGrayColor()
// self.locationManager.requestAlwaysAuthorization()
if CLLocationManager.locationServicesEnabled() {
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters
locationManager.startUpdatingLocation()
}
}
我的问题如下。 如果用户按下“不授权”我如何得到他的选择,以便我可以将他发回给以前的视图控制器或警告他我留下的消息?
这在我的情况下是正确的!谢谢! –
