iOS和斯威夫特:显示距当前位置的距离? [英] iOS & Swift: display distance from current location?

问题描述

我已经检查了互连网和stackoverflow，但找不到解决我问题的方法.

I have scoured the interwebs and stackoverflow, and I can't find a solution to my problem.

我正在尝试:

1. 获取用户的当前位置(经纬度)
2. 计算用户当前位置与我在内部设置的另一个位置(经纬度)之间的距离
3. 在列表视图中返回距离

到目前为止，如果我手动设置当前位置，但可以更新，则可以完成此操作.

So far, I can accomplish this if I manually set my current location, but I need to to update.

我已经成功返回了日志中的当前位置(我在Simulator中将其设置为Apple总部)，但是在实际的应用程序或模拟器中却没有成功.

I have had success returning my current location (I set it as Apple headquarters in the Simulator) in the log, but no success in the actual app or simulator.

这就是我所拥有的:

import UIKit
import CoreLocation
import MapKit

class ViewController: UITableViewController, CLLocationManagerDelegate, MKMapViewDelegate {




override func prefersStatusBarHidden() -> Bool {
    return true
}


var shops = [coffeeShop]()

var locationManager = CLLocationManager()


override func viewDidLoad() {
    super.viewDidLoad()



    // Ask for Authorisation from the User.
    self.locationManager.requestAlwaysAuthorization()

    // For use in foreground
    self.locationManager.requestWhenInUseAuthorization()

    if CLLocationManager.locationServicesEnabled() {
        locationManager.delegate = self
        locationManager.desiredAccuracy = kCLLocationAccuracyBest
        locationManager.startUpdatingLocation()
    }




    loadShops()

}


func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    let locValue:CLLocationCoordinate2D = manager.location!.coordinate
            print("locations = \(locValue.latitude) \(locValue.longitude)")

}


func loadShops() {

    let currentLocation = CLLocation()
    let currentLat = currentLocation.coordinate.latitude
    let currentLong = currentLocation.coordinate.longitude


    var myLocation = CLLocation(latitude: currentLat, longitude: currentLong)


    let shopLocation1 = CLLocation(latitude: 39.7886939, longitude: -86.1547275)
    let distance1 = myLocation.distanceFromLocation(shopLocation1) / 1000
    let shop1 = coffeeShop(location: distance1)!

}

此外，我在info.plist中设置了所有内容以及所有这些好东西.

In addition, I have everything set in the info.plist and all of that good stuff.

我该怎么做！?* 轻声哭泣 *

HOW DO I MAKE THIS WORK!? * weeps softly *

在此先感谢您的帮助！

推荐答案

我能够使用以下代码来实现所需的功能.有时，您只是将其放置在宇宙中，以使宇宙自行响应.谢谢大家的帮助！

I was able to use the following code to achieve what I needed. Sometimes you just gotta put it out there in the universe for the universe to respond on its own. Thanks everyone for the help!

        let currentLat = self.locationManager.location!.coordinate.latitude
        let currentLong = self.locationManager.location!.coordinate.longitude
