Ios 我想用swift代码访问第二个视图控制器中的var

嗨，这是我到目前为止的代码

import UIKit
import MapKit
import CoreLocation

class ViewController: UIViewController, MKMapViewDelegate, CLLocationManagerDelegate {

    @IBOutlet var map: MKMapView!
    var locationManager = CLLocationManager()

    override func viewDidLoad() {
        super.viewDidLoad()
        locationManager.delegate = self
        locationManager.desiredAccuracy = kCLLocationAccuracyBest
        locationManager.requestWhenInUseAuthorization()
        locationManager.startUpdatingLocation()
    }

    func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) {
        var userLocation:CLLocation = locations[0] as! CLLocation
        var latitude = userLocation.coordinate.latitude
        var longitude = userLocation.coordinate.longitude
        var latDelta:CLLocationDegrees = 0.05
        var lonDelta:CLLocationDegrees = 0.05
        var span:MKCoordinateSpan = MKCoordinateSpanMake(latDelta, lonDelta)
        var location:CLLocationCoordinate2D = CLLocationCoordinate2DMake(latitude, longitude)   
        var region:MKCoordinateRegion = MKCoordinateRegionMake(location, span)

        self.map.setRegion(region, animated: false)
        println(latitude)
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
    }
}

我想在显示

纬度

、

经度

、

航向

和

速度的第二视图控制器中访问
位置管理器
功能中的信息。我是个新手，所以任何帮助都会很好。干杯

将要传递给第二个VC的变量从本地范围移动到类范围：

import UIKit
import MapKit
import CoreLocation

class ViewController: UIViewController, MKMapViewDelegate, CLLocationManagerDelegate {

    @IBOutlet var map: MKMapView!


   var locationManager = CLLocationManager()
   var longitude:CLLocationDegrees!
   var latitude:CLLocationDegrees!

  override func viewDidLoad() {
    super.viewDidLoad()
    locationManager.delegate = self
    locationManager.desiredAccuracy = kCLLocationAccuracyBest
    locationManager.requestWhenInUseAuthorization()
    locationManager.startUpdatingLocation()
}


使用变量创建目标UIViewController以保存传递的值：

import UIKit
import MapKit
import CoreLocation

class MyDestinationViewController: UIViewController {
  var longitude:CLLocationDegrees!
  var latitude:CLLocationDegrees!

    override func viewDidLoad() {
        super.viewDidLoad()
    }
}


将
prepareforsgue
方法添加到要从中发送数据的viewcontroller：

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    let destinationVC = segue.destinationViewController as! MyDestinationViewController
    destinationVC.latitude = latitude
    destinationVC.longitude = longitude
}


如果您不想使用segue，您可以在演示VC之前实例化targetViewController并传递变量。
非常感谢您为我整理了它，感谢您的快速回复。
