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)")        }    }}
