iOS框架的核心位置

Question

我正在创建一个iOS框架，我想使用Core Location与Beacons进行交互。出于测试原因，我试图获得用户位置。

这是我在框架中创建的类。

import Foundation
import CoreLocation

 public class BeaconManager:NSObject,CLLocationManagerDelegate{

    var locationManager:CLLocationManager = CLLocationManager()

    public override init() {
        super.init()
        locationManager.requestAlwaysAuthorization()
        locationManager.delegate = self
        locationManager.startUpdatingLocation()
    }

     public func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) {
        if let location = locations.first as? CLLocation {
            println(location)
        }
    }
}

我从具有这样框架的测试应用程序调用它

import UIKit
import OtravitaSDK
import CoreLocation

class ViewController: UIViewController {

      var bm = BeaconManager()

    override func viewDidLoad() {
        super.viewDidLoad()


        // Do any additional setup after loading the view, typically from a nib.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


}

但是不工作，不打印位置。我在框架的info.plist和app的info.plist中都设置了NSLocationAlwaysUsageDescription

Answer 1

你可以添加你的描述在qazxsw poi＆qazxsw poi in plist

这段代码放入NSLocationAlwaysUsageDescription文件中

NSLocationWhenInUseUsageDescription

Answer 2

从iOS 8开始，您需要做的是配置AppDelegate以满足2种位置行为。您需要提供默认情况下显示弹出窗口的默认消息，要求用户同意使用其位置。

     var locationManager:CLLocationManager?

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

      //You can give this permission for fetch current location
        var type = UIUserNotificationType.Badge | UIUserNotificationType.Alert | UIUserNotificationType.Sound;
        var setting = UIUserNotificationSettings(forTypes: type, categories: nil);
        UIApplication.sharedApplication().registerUserNotificationSettings(setting);
        UIApplication.sharedApplication().registerForRemoteNotifications();

        locationManager = CLLocationManager()
        locationManager?.requestAlwaysAuthorization()
        locationManager?.delegate = self
        locationManager?.startUpdatingLocation()

        // Override point for customization after application launch.
        return true
    }

    func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) {
        if let location = locations.first as? CLLocation {
            println(location)
        }
    }

和Info.plist file

有关完整演练的信息，请参阅NSLocationWhenInUseUsageDescription，讨论此主题的NSLocationAlwaysUsageDescription。希望这可以帮助！

您可以首先创建将实现CLLocationManagerDelegate的记者类（带有共享实例），这样您就可以在委托方法中实现您的逻辑

接下来，您可以创建一个Client类

最后在您需要的地方调用Client方法

import Foundation
import CoreLocation

class LocationReporter: NSObject, CLLocationManagerDelegate {

    static let sharedInstance = LocationReporter()

    func startUpdating(locationManager: CLLocationManager) {
        locationManager.delegate = self
        locationManager.requestAlwaysAuthorization()
        locationManager.desiredAccuracy = kCLLocationAccuracyBest
        locationManager.startUpdatingLocation()
    }

    func stopUpdating(locationManager: CLLocationManager) {
        locationManager.stopUpdatingLocation()
    }

    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        if let location = locations.first {
            print("latitude: ", location.coordinate.latitude)
            print("longitude: ", location.coordinate.longitude)
        }
    }

  //implement other locationManger delegate methods


}

希望这会有所帮助
