当用户在Swift中禁用位置时，如何显示警报？

我的Swift应用程序要求允许通过CLLocationManager访问当前位置。当用户点击“不允许”时，如何显示警报消息？

您要查看

func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) 

及

第一个在用户更改授权状态时调用，第二个将允许您随时确定当前状态

然后，显示消息，例如：

let alert = UIAlertController(title: "Your title", message: "GPS access is restricted. In order to use tracking, please enable GPS in the Settigs app under Privacy, Location Services.", preferredStyle: UIAlertControllerStyle.Alert)
            alert.addAction(UIAlertAction(title: "Go to Settings now", style: UIAlertActionStyle.Default, handler: { (alert: UIAlertAction!) in
                print("")
                UIApplication.sharedApplication().openURL(NSURL(string:UIApplicationOpenSettingsURLString)!)
            }))

上面的代码显示警报，并允许用户直接转到设置以启用位置

救命啊，@MirekE！谢谢：）“authorizationStatus（）”在iOS 14.0中被弃用。。。见主题：

let alert = UIAlertController(title: "Your title", message: "GPS access is restricted. In order to use tracking, please enable GPS in the Settigs app under Privacy, Location Services.", preferredStyle: UIAlertControllerStyle.Alert)
            alert.addAction(UIAlertAction(title: "Go to Settings now", style: UIAlertActionStyle.Default, handler: { (alert: UIAlertAction!) in
                print("")
                UIApplication.sharedApplication().openURL(NSURL(string:UIApplicationOpenSettingsURLString)!)
            }))
