Hy伙计们,
我正在使用 swift 3.0创建一个应用程序,但我很快遇到了一个问题.我设置必要的功能来请求使用位置的权限,但每次运行应用程序时都会出现同样的错误… Viewcontroller.h import UIKit
import MapKit
class ViewController: UIViewController {
let locationManager = CLLocationManager()
override func viewDidLoad() {
super.viewDidLoad()
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestWhenInUseAuthorization()
locationManager.requestLocation()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
extension ViewController : CLLocationManagerDelegate {
private func locationManager(manager: CLLocationManager,didChangeAuthorizationStatus status: CLAuthorizationStatus) {
if status == .authorizedWhenInUse {
locationManager.requestLocation()
}
}
private func locationManager(manager: CLLocationManager,didUpdateLocations locations: [CLLocation]) {
if locations.first != nil {
print("location:: (location)")
}
}
private func locationManager(manager: CLLocationManager,didFailWithError error: NSError) {
print("error:: (error)")
}
}

我是swift 3.0的新手,但是我找不到任何关于如何解决这个问题的事情(我在stackoverflow上查了一下但是他们给出的答案并没有帮助我…) 解决方法
您使用的是xcode8和swift3,但您的委托方法是从swift复制的.2.更改您的委托方法,如下所示.
extension ViewController : CLLocationManagerDelegate {
func locationManager(_ manager: CLLocationManager,didFailWithError error: Error) {
print("error:: (error.localizedDescription)")
}
func locationManager(_ manager: CLLocationManager,didChangeAuthorization status: CLAuthorizationStatus) {
if status == .authorizedWhenInUse {
locationManager.requestLocation()
}
}
func locationManager(_ manager: CLLocationManager,didUpdateLocations locations: [CLLocation]) {
if locations.first != nil {
print("location:: (location)")
}
}
}
