Swift - 使用CoreLocation实现定位（经纬度、海拔、速度、距离等）

（1）在 info.plist里加入定位描述（Value值为空也可以）：

NSLocationWhenInUseDescription ：允许在前台获取GPS的描述

NSLocationAlwaysUsageDescription ：允许在后台获取GPS的描述

（2）代码如下：

import UIKit
import CoreLocation

class ViewController: UIViewController, CLLocationManagerDelegate {

//定位管理器
let locationManager:CLLocationManager = CLLocationManager()

@IBOutlet weak var label1: UILabel!
@IBOutlet weak var label2: UILabel!
@IBOutlet weak var label3: UILabel!
@IBOutlet weak var label4: UILabel!
@IBOutlet weak var label5: UILabel!
@IBOutlet weak var label6: UILabel!
@IBOutlet weak var label7: UILabel!

override func viewDidLoad() {
super.viewDidLoad()

//设置定位服务管理器代理
locationManager.delegate = self
//设置定位进度
locationManager.desiredAccuracy = kCLLocationAccuracyBest
//更新距离
locationManager.distanceFilter = 100
////发送授权申请
locationManager.requestAlwaysAuthorization()
if (CLLocationManager.locationServicesEnabled())
{
//允许使用定位服务的话，开启定位服务更新
locationManager.startUpdatingLocation()
print("定位开始")
}
}

//定位改变执行，可以得到新位置、旧位置
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
//获取最新的坐标
let currLocation:CLLocation = locations.last!
label1.text = "经度：\(currLocation.coordinate.longitude)"
//获取纬度
label2.text = "纬度：\(currLocation.coordinate.latitude)"
//获取海拔
label3.text = "海拔：\(currLocation.altitude)"
//获取水平精度
label4.text = "水平精度：\(currLocation.horizontalAccuracy)"
//获取垂直精度
label5.text = "垂直精度：\(currLocation.verticalAccuracy)"
//获取方向
label6.text = "方向：\(currLocation.course)"
//获取速度
label7.text = "速度：\(currLocation.speed)"
}
}
