我运行了代码来获取用户的位置，这是我得到的错误。有人可以帮我解决一下吗？
我的代码如下:
import UIKit
import CoreLocation
class ViewController: UIViewController, CLLocationManagerDelegate {
@IBOutlet weak var citybtn: UIButton!
@IBOutlet weak var citylbl: UILabel!
let locationManager = CLLocationManager()
var currentLocation : CLLocation!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
// Used to start getting the users location
//let locationManager = CLLocationManager()
// For use when the app is open
//locationManager.requestAlwaysAuthorization()
// If location services is enabled get the users location
//if CLLocationManager.locationServicesEnabled() {
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest // You can change the locaiton accuary here.
locationManager.requestWhenInUseAuthorization()
}
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(true)
locationAuthStatus()
}
func locationAuthStatus() {
if CLLocationManager.authorizationStatus() == .authorizedWhenInUse {
currentLocation = locationManager.location
print(currentLocation.coordinate.latitude)
print(currentLocation.coordinate.longitude)
} else {
locationManager.requestWhenInUseAuthorization()
locationAuthStatus()
}
}
@IBAction func buttonpresses(_ sender: Any) {
}
}
最佳答案
听起来您没有启用目标的位置更新功能:
- 选择目标
- 选择功能
- 在后台模式中，勾选位置更新
关于ios - 使用 swift 制作一个获取用户位置的应用程序，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/44749388/
