方法1，代码设置

import UIKit
//1，导入CoreLocation
import CoreLocation

class ViewController: UIViewController {
    //2，懒加载CLLocationManager
    lazy var locationM : CLLocationManager = {
        let locationM = CLLocationManager()
      //3，设置代理
        locationM.delegate = self
        return locationM

    }()

    override func viewDidLoad() {
        super.viewDidLoad()

 //发送请求，调用该方法，只在App进入前台时候进行定位，并且需要在info.plist中加上NSLocationWhenInUseUsageDescription这个键，值随便填
if #available(iOS 8.0, *) {//版本设置
        locationM.requestWhenInUseAuthorization()
}
        //6，启动定位
        locationM.startUpdatingLocation()
    }

}
//遵守协议
extension ViewController : CLLocationManagerDelegate {
  //4，实现代理方法
    func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) ｛
        print(locations)
        print("-----")
    }
}

方法二

import CoreLocation

class ViewController: UIViewController {
    //2，懒加载CLLocationManager
    lazy var locationM : CLLocationManager = {
        let locationM = CLLocationManager()
      //3，设置代理
        locationM.delegate = self
        return locationM

    }()

    override func viewDidLoad() {
        super.viewDidLoad()
//发送请求，调用该方法，只在App进入前台时候进行定位，并且需要在info.plist中加上NSLocationWhenInUseUsageDescription这个键，值随便填
        if #available(iOS 8.0, *) {
            locationM.requestWhenInUseAuthorization()
            if #available(iOS 9.0, *) {
//IOS9.0之后必须设置该属性为true，才能在Xcode里设置后台运行之后后台定位
                locationM.allowsBackgroundLocationUpdates = true
            }
        }

        //6，启动定位
        locationM.startUpdatingLocation()
    }

}
//遵守协议
extension ViewController : CLLocationManagerDelegate {
  //4，实现代理方法
    func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) ｛
        print(locations)
        print("-----")
    }
}
