Swift 如何将经度和纬度变量传递给另一个函数？

我有“locationManager”功能，可以在其中创建和设置经度和纬度。我想做的是当按下按钮时能够得到那个位置。当我按下该按钮时，如何将经度和纬度输入@iAction？谢谢你的帮助

import UIKit
import CoreLocation

class ViewController: UIViewController, CLLocationManagerDelegate {

    let locationManager = CLLocationManager()

    override func viewDidLoad() {
        super.viewDidLoad()

        setupLocationManager()
    }

    func setupLocationManager() {
        locationManager.delegate = self
        locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters
        locationManager.requestWhenInUseAuthorization()
        locationManager.startUpdatingLocation()
    }

    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        if let location = locations.last {
            if location.horizontalAccuracy > 0 {
                locationManager.stopUpdatingLocation()

                let longitude = location.coordinate.longitude
                let latitude = location.coordinate.latitude

                print("longitude = \(longitude)")
                print("latitude = \(latitude)")


            }
        }
    }


    func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
        print("Location update failed, \(error)")
    }


    @IBAction func buttonPressed(_ sender: UIButton) {
        // print(longitude)
    }

}

如果类的作用域为，则定义位置变量

fileprivate var mylocation:CLLocation?

设置我的位置

 func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        if let location = locations.last {
            if location.horizontalAccuracy > 0 {
                locationManager.stopUpdatingLocation()

                myLocation = location
            }
        }
    }

现在您可以在点击按钮时访问位置

@IBAction func buttonPressed(_ sender: UIButton) {
                let longitude = myLocation.coordinate.longitude
                let latitude = myLocation.coordinate.latitude

                print("longitude = \(longitude)")
                print("latitude = \(latitude)")
    }

不评论代码的体系结构；每当调用locationManager（）时，在print（）语句所在的行中，为什么不将值存储到类变量中，以便在buttonPressed（）中读取这些值？所以两个变量就在你的let locationManager=。。。
