Ios stopUpdateLocation（）不´；工作不快

当我执行segue时，位置仍会在下一个VC中更新。我尝试将startUpdatingLocation（）放入超级视图以外的其他函数中，但没有任何更改。你知道我能做什么吗？格吕埃·奥斯·曼海姆

import UIKit
import MapKit
import CoreLocation

class uploadPrepare: UIViewController, UITextViewDelegate,    CLLocationManagerDelegate {


@IBOutlet weak var weiterButton: UIButton!

let locationPrepare = CLLocationManager()

var regionPrepare: MKCoordinateRegion!


override func viewDidLoad() {

    super.viewDidLoad()


    locationPrepare.delegate = self
    locationPrepare.desiredAccuracy = kCLLocationAccuracyBest
    locationPrepare.requestWhenInUseAuthorization()
    locationPrepare.startUpdatingLocation()

}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}


func weiterButtonTapped(_ sender: UIButton){

    self.locationPrepare.stopUpdatingLocation()
    self.performSegue(withIdentifier: "goToMapCheck", sender: self)
}

func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {

    let locationPrepare = locations[0]
    let myLocationPrepare:CLLocationCoordinate2D = CLLocationCoordinate2DMake(locationPrepare.coordinate.latitude,locationPrepare.coordinate.longitude)
    let span: MKCoordinateSpan = MKCoordinateSpanMake(0.0005,0.0005)
        regionPrepare = MKCoordinateRegionMake(myLocationPrepare,span)

    print("\(locationPrepare.coordinate.latitude)")

}

override func prepare(for segue: UIStoryboardSegue, sender: Any?)
{

    let uploadInterfaceGoing = segue.destination as! mapCheck
    uploadInterfaceGoing.regionReceived = regionPrepare   
}

}

实际上，在调用stopUpdateLocation（）函数后，CLLocationManager仍会多次回调。最新的位置是最准确的。如果您想立即停止调用

didUpdateLocations

，只需在StopUpdateLocation.hmm之后设置

self.locationPrepare.delegate=nil

，它仍然会将位置i put sender更新为Any，并且有效。谢天谢地，在调用StopUpdateLocation（）函数后，CLLocationManager仍然会回调多次。最新的位置是最准确的。如果您想立即停止调用

didUpdateLocations

，只需在StopUpdateLocation.hmm之后设置

self.locationPrepare.delegate=nil

，它仍然会将位置i put sender更新为Any，并且有效。谢谢
